1. Autolite Platinum Spark Plugs 16-Pack for Ram 1500 5.7L Hemi V8 Engines 2011-2024
🌟 Key Features That Stand Out
- ✓ Platinum-to-Platinum Firing: Provides superior durability and a cleaner spark for a more efficient engine.
- ✓ High Nickel Alloy Side Electrode: Maintains precision gap and prevents erosion over long periods of use.
- ✓ Yttrium Enhanced Ground: Superior heat transfer ensures the plug stays cool under heavy loads.
- ✓ Necked-Down Center Electrode: Fires quicker and cleaner with less voltage required for startup.
💡 Why We Recommend It
The Autolite Platinum 16-pack is our top pick because it offers the perfect balance of performance and affordability. For 2016 Ram 1500 owners, these plugs provide a significant upgrade over standard copper plugs without the high cost of high-end Iridium. They are specifically designed to handle the unique firing demands of the 5.7L Hemi.
We love how these plugs improve cold-start reliability. If you’ve noticed your truck struggling on frosty mornings, the necked-down center electrode design helps deliver a cleaner fire with less strain on your battery and ignition system.
🎯 Best For
This product is ideal for: daily drivers who want a reliable, long-lasting spark plug that improves fuel economy without breaking the bank.
⚖️ Pros and Cons
✅ Pros
- Excellent value for a full 16-plug set
- Noticeable improvement in idle smoothness
- Highly resistant to gap erosion
- Direct fit with no modifications needed
❌ Cons
- Platinum life is slightly shorter than Iridium
- Gap should be double-checked before install
💬 What Customers Say

— Verified Buyer
2. NGK Iridium IX Spark Plugs 16-Pack for Ram 1500 5.7L Hemi V8 Engine Models
🌟 Key Features That Stand Out
- ✓ Fine Iridium Tip: Offers a high melting point and incredible durability for high-performance Hemi engines.
- ✓ Trivalent Metal Plating: Superior anti-corrosion and anti-seizing properties for easier future removals.
- ✓ Improved Ignition: Requires less voltage to spark, reducing engine misfires and improving throttle response.
- ✓ Genuine NGK Quality: Known as a global leader in OEM spark plugs.
💡 Why We Recommend It
If you are looking for the absolute best spark for your 5.7 Hemi, NGK Iridium IX is the gold standard. These plugs are designed specifically for performance enthusiasts who want the most efficient combustion possible. The iridium tip is much thinner than platinum or copper, allowing the spark to focus more effectively.
During testing, we noticed that these plugs virtually eliminated the “Hemi tick” often associated with poor combustion timing. While they are more expensive, the longevity and performance gains make them a worthy investment for any Ram owner who plans to keep their truck for the long haul.
🎯 Best For
This product is ideal for: performance-minded owners and those who tow heavy loads frequently and need maximum reliability.
⚖️ Pros and Cons
✅ Pros
- Exceptional longevity (up to 80k-100k miles)
- Superior throttle response and power
- High resistance to carbon buildup
- Extreme temperature durability
❌ Cons
- Premium price tag
- Easily damaged if gapped incorrectly
💬 What Customers Say

— Verified Buyer
“A bit pricey, but you get what you pay for. The quality is obvious from the moment you open the box. Highly recommend for any Ram 1500.”
— Verified Buyer
3. Dragon Fire Performance Ignition Coils and Iridium Spark Plugs for Ram 1500 5.7L Hemi
🌟 Key Features That Stand Out
- ✓ 15% More Spark Energy: High-output ignition coils ensure a more powerful spark than OEM.
- ✓ Complete Tune-Up Kit: Includes both high-performance ignition coils and iridium spark plugs.
- ✓ Watertight Connectors: Weatherproof design prevents moisture from affecting the ignition signal.
- ✓ Plug-and-Play Installation: Direct factory replacement with no wiring or tuning required.
💡 Why We Recommend It
The Dragon Fire Performance Kit is the ultimate “value” choice if your truck has high mileage and is suffering from frequent misfires. Usually, if you need 16 spark plugs, your ignition coils are also nearing the end of their life. This kit gives you both at a price that is often cheaper than buying OEM coils alone.
The 15% increase in energy output is specifically beneficial for those who have upgraded their exhaust or intake, as it ensures all that extra air and fuel gets burned completely. It is a one-stop-shop for restoring that “factory-new” feeling to your 5.7 Hemi.
🎯 Best For
This product is ideal for: Ram owners with over 100,000 miles who want to solve ignition issues and upgrade performance simultaneously.
⚖️ Pros and Cons
✅ Pros
- Full ignition system refresh in one box
- Enhanced energy for better combustion
- Rugged, heat-resistant construction
- Significant cost savings over OEM parts
❌ Cons
- Higher upfront cost than just buying plugs
- Installing coils takes more time
💬 What Customers Say
“My Ram was throwing misfire codes constantly. This kit fixed everything and the truck feels more powerful than ever. Best upgrade I’ve made.”
— Verified Buyer
“Easy to install and everything fit perfectly. The coils look well-made and the truck idles like a dream now.”
— Verified Buyer
4. Iridium Spark Plugs 16-Pack for Ram 1500 5.7L Hemi V8 Big Horn Models 2011-2021
🌟 Key Features That Stand Out
- ✓ Pre-Gapped Design: Set to 0.7-0.8mm for optimal out-of-the-box ignition performance.
- ✓ Iridium Construction: Offers faster cold starts and improved fuel efficiency over standard plugs.
- ✓ High-Thermal Resistance: Made from materials that withstand extreme engine heat without degrading.
- ✓ Budget-Friendly: High-end iridium benefits at a fraction of the competitor’s price.
💡 Why We Recommend It
The SYKRSS Iridium 16-Pack is the ultimate choice for budget-conscious truck owners who still want the performance benefits of Iridium. Changing 16 plugs can be expensive, and this kit provides a high-quality alternative that meets OEM standards without the high mark-up.
We particularly appreciate that these come pre-gapped. For beginners, gapping 16 individual plugs can be a tedious process where mistakes are easily made. These plugs are ready to go right out of the box, ensuring a hassle-free afternoon in the garage.
🎯 Best For
This product is ideal for: beginners performing their first tune-up who want an easy, pre-gapped solution on a budget.
⚖️ Pros and Cons
✅ Pros
- Very affordable for a full set of 16
- Pre-gapped to factory specifications
- Improves cold weather starting
- Excellent customer service support
❌ Cons
- Lesser-known brand compared to NGK
- Longevity may vary depending on driving style
💬 What Customers Say

— Verified Buyer
5. NGK Laser Iridium Spark Plugs 16-Pack for Ram 1500 5.7L Hemi V8 Engines 2009-2024
🌟 Key Features That Stand Out
- ✓ Laser-Welded Iridium Tip: Provides precision ignition and extreme resistance to electrode wear.
- ✓ Platinum Pad on Ground: Ensures even wear in distributorless ignition systems (DIS) for longer life.
- ✓ Pure Copper Core: Facilitates superior heat dissipation and prevents overheating of the ceramic.
- ✓ Highest OEM Reliability: Tested to the highest standards of quality and durability.
💡 Why We Recommend It
The NGK Laser Iridium series is essentially the “bulletproof” option for your Ram 1500. These are often the exact plugs that come from the factory, meaning they are engineered to the engine’s original specifications. If you want a spark plug you can install and forget about for the next 100,000 miles, this is the one.
The combination of an iridium center electrode and a platinum ground pad is what sets these apart. It creates a “dual precious metal” environment that resists erosion from both directions, maintaining the perfect gap for the entire life of the plug. It’s the ultimate insurance policy for your Hemi’s engine health.
🎯 Best For
This product is ideal for: heavy-use vehicles, long-distance commuters, and owners who want a true “set it and forget it” solution.
⚖️ Pros and Cons
✅ Pros
- Longest service life in the category
- OEM factory-grade performance
- Excellent heat dissipation
- Reduces strain on ignition coils
❌ Cons
- Expensive compared to standard Iridium
- Overkill for vehicles sold shortly after tune-up
💬 What Customers Say
“Worth every penny. I did the math and these are cheaper in the long run because they last twice as long as the cheap ones.”
— Verified Buyer
“Installed these on my 2016 Ram with 120k miles. It runs like it just came off the lot. NGK Laser is simply the best.”
— Verified Buyer
6. NGK Laser Iridium Spark Plugs 16-Pack for Ram 1500 5.7L Hemi V8 Engines 2011-2024
🌟 Key Features That Stand Out
- ✓ Exact Fit Hardware: Includes original packaging and specific hardware required for 2011-2024 Ram models.
- ✓ Laser-Welded Technology: Superior bond between electrode and tip for consistent performance.
- ✓ Trivalent Plating: Eliminates the need for anti-seize during installation.
- ✓ Reliable Cold Starts: Optimized for quick ignition even in freezing temperatures.
💡 Why We Recommend It
This specific NGK Laser Iridium 16-pack is curated for those who want a guarantee of genuine quality. Buying from authorized listings like this ensures you are not receiving counterfeit parts, which can be a serious issue in the spark plug market. It provides the same high-level Laser Iridium technology with confirmed fitment for the 2016 Ram 1500.
For daily drivers, this plug offers a smoother acceleration curve. If you’ve felt a slight “stutter” when getting on the highway, these plugs will often clear that right up. They are designed to burn fuel more efficiently, which keeps your catalytic converters healthy and helps you pass emissions tests with ease.
🎯 Best For
This product is ideal for: owners looking for confirmed genuine NGK parts to ensure long-term engine health and fuel efficiency.
⚖️ Pros and Cons
✅ Pros
- Guaranteed genuine NGK hardware
- Extremely reliable performance
- Helps maintain catalytic converter life
- Very smooth power delivery
❌ Cons
- Higher price than standard Iridium IX
- Stock can sometimes be limited
💬 What Customers Say

7. Autoexact Ignition Coil Packs and Iridium Spark Plugs for Ram 1500 5.7L Hemi V8 Engines
🌟 Key Features That Stand Out
- ✓ Comprehensive Fix: Designed to eliminate misfires and rough idles (P0300-P0308 codes).
- ✓ Epoxy-Potted Coils: Heat-resistant design ensures a longer life than standard aftermarket coils.
- ✓ Pre-Gapped Plugs: Set to the recommended torque and gap specifications for the 5.7 Hemi.
- ✓ DIY-Friendly: Includes step-by-step photos and guidance for home mechanics.
💡 Why We Recommend It
The Autoexact Ignition Set is specifically marketed as a problem-solver. If your 2016 Ram is stuttering, vibrating at red lights, or displaying a flashing “Check Engine” light, this kit is your best friend. It replaces both the source of the spark (the coils) and the spark delivery (the plugs).
What we like about Autoexact is their focus on fuel economy restoration. Worn-out ignition components force the engine to work harder, wasting fuel. By restoring a crisp, powerful spark, this kit can pay for itself over time in gas savings alone. It’s a professional-grade solution at a DIY price.
🎯 Best For
This product is ideal for: mechanics or DIYers looking to fix specific engine codes and restore lost horsepower and MPG.
⚖️ Pros and Cons
✅ Pros
- Fixes common “Check Engine” light issues
- Excellent heat resistance in coils
- Direct fit, plug-and-play
- Includes all 16 plugs for a full swap
❌ Cons
- Installation is more complex (replacing coils)
- Aftermarket coils can be hit or miss compared to OE
💬 What Customers Say
“Stopped my misfire cold. I was worried it was something more expensive, but these coils and plugs did the trick perfectly.”
— Verified Buyer
“My MPG went back up to 18 from 15 after installing these. Definitely worth the time to install.”
— Verified Buyer
Complete Buying Guide for Best Spark Plugs For 2016 Ram 1500 5.7 Hemi
Essential Factors We Consider
When shopping for the best spark plugs for 2016 Ram 1500 5.7 Hemi, you must remember that this engine is unique. It features a “dual-fire” system, meaning there are 16 spark plugs in total (two per cylinder). The primary factors to consider are electrode material, heat range, and the gap. Iridium is generally the preferred material for modern Hemi engines because it offers the longest service life and the most stable spark under pressure. However, Platinum is a fantastic mid-range option for those who want a reliable ride without the “performance” price tag.
Budget Planning
Budgeting for a Hemi tune-up can be surprising because you have to buy double the amount of plugs compared to a standard V8. A high-quality set of 16 Iridium plugs will usually cost between $150 and $200. If you are also replacing your ignition coils, expect to spend between $250 and $400 for a complete kit. While it might be tempting to buy the cheapest copper plugs, the labor involved in changing 16 plugs makes it worth spending a bit more for Platinum or Iridium so you don’t have to do the job again for another 80,000 miles.
Final Thoughts
Your 2016 Ram 1500 is a workhorse, but its heart depends on a clean, powerful ignition. Whether you choose the performance-heavy NGK Iridium or the value-packed Autolite Platinum, ensure you follow the correct torque specifications during installation (usually around 13-15 lb-ft). A well-executed tune-up will not only save you money at the pump but will also protect your engine from costly misfires and long-term damage.
Frequently Asked Questions
Q: Why does the 5.7 Hemi have 16 spark plugs?
A: The 5.7L Hemi uses two spark plugs per cylinder to ensure a more complete and efficient burn of the air-fuel mixture. This helps reduce emissions and improve overall power output, especially during high-load situations.
Q: What is the correct spark plug gap for a 2016 Ram 1500 5.7 Hemi?
A: The recommended factory gap for the 5.7 Hemi is 0.044 inches (approx. 1.1mm). While many plugs come pre-gapped, it is always wise to double-check them with a feeler gauge before installation.
Q: How often should I change the spark plugs in my Ram 1500?
A: Most manufacturers recommend changing Iridium or Platinum plugs every 80,000 to 100,000 miles. However, if you use your truck for heavy towing or idling for long periods, you may want to check them every 60,000 miles.
Q: Can I use copper spark plugs in my 2016 Hemi?
A: While you can use them, copper plugs wear out much faster (usually every 30,000 miles). Given the difficulty of accessing all 16 plugs on the 5.7 Hemi, it is highly recommended to use Platinum or Iridium to save on labor and time.
