Complete Buying Guide for Best Spark Plugs For 2019 Ram 1500 5.7 Hemi
Essential Factors We Consider
Choosing the best spark plugs for your 2019 Ram 1500 5.7 Hemi involves more than just picking a brand. The Hemi engine is known for its robust power and efficiency, which relies heavily on a precise and consistent ignition spark. Here are the critical factors we evaluated to determine our top recommendations:
- ✓ Compatibility: First and foremost, the spark plugs must be a direct fit for the 2019 Ram 1500 with the 5.7L Hemi engine. This includes ensuring the correct thread size, reach, and heat range. Our recommendations are all confirmed to fit this specific vehicle.
- ✓ Electrode Material: The type of material used for the electrode significantly impacts performance and longevity.
- • Copper: Excellent conductivity, but shorter lifespan due to softer material. Generally used in older vehicles or for specific performance tunings.
- • Platinum: More durable than copper, offering a longer lifespan (around 60,000 miles). Good balance of performance and cost.
- • Iridium: The hardest and most durable material, providing the longest lifespan (up to 100,000 miles or more) and a consistently strong spark. Ideal for modern, high-performance engines like the Hemi. Many of our top picks feature iridium.
- • Ruthenium: An advanced precious metal alloy, offering even greater ignitability and longevity than iridium, particularly under demanding engine conditions. The NGK Ruthenium HX series is a prime example.
- ✓ Spark Plug Gap: The 5.7 Hemi typically requires a specific spark plug gap (often 0.044 inches). While many performance plugs come pre-gapped, always double-check and adjust if necessary to ensure optimal combustion and prevent misfires.
- ✓ Ignition Coil Integration (for Combo Kits): For a 2019 Ram 1500 5.7 Hemi, it’s often beneficial to replace both spark plugs and ignition coils simultaneously, especially if experiencing significant performance issues. Combo kits offer matched components designed to work together, simplifying the process and ensuring system synergy.
- ✓ Brand Reputation and Quality: Sticking with reputable brands like NGK, E3, and specialized aftermarket manufacturers ensures you’re getting components that meet stringent quality controls and performance standards. Genuine quality parts mean reliability and consistent performance.
- ✓ Performance Benefits: Look for plugs that promise specific benefits like increased horsepower, improved fuel economy, smoother idle, reduced misfires, and quicker throttle response. These are tangible improvements that enhance the driving experience of your Ram 1500.
- ✓ Durability and Longevity: High-quality spark plugs, especially those made with platinum, iridium, or ruthenium, offer extended service intervals, saving you time and money on frequent replacements.
Budget Planning
Investing in quality spark plugs for your 2019 Ram 1500 5.7 Hemi is an investment in your truck’s long-term health and performance. While cheaper options might exist, they often come with compromises in material quality, lifespan, and overall engine efficiency. Consider the following when budgeting:
- ✓ Spark Plugs Only: If your ignition coils are in good shape, a set of 16 high-quality iridium or ruthenium spark plugs will be the most cost-effective solution. Expect to pay more for premium materials but gain significantly in longevity and performance.
- ✓ Coil and Plug Combo Kits: These represent a higher initial outlay but offer a complete ignition system refresh. If your vehicle has high mileage or you’re experiencing multiple ignition-related issues, a combo kit provides peace of mind and often better overall value than replacing components separately over time. Our “Best Choice” and “Editor’s Choice” fall into this category, representing a more significant but worthwhile investment for optimal Hemi performance.
- ✓ Installation Costs: While changing spark plugs on a Hemi can be a DIY project for experienced mechanics, it can be challenging due to engine bay access, especially for the rear cylinders. Factor in potential professional installation costs if you’re not comfortable tackling the job yourself.
Remember, the goal isn’t just the lowest price, but the best value – combining performance, durability, and reliability for your specific Ram 1500 needs.
Final Thoughts
Selecting the right spark plugs for your 2019 Ram 1500 5.7 Hemi is a crucial maintenance step that directly influences your truck’s power, fuel economy, and driving experience.

Frequently Asked Questions
Q: How many spark plugs does a 2019 Ram 1500 5.7 Hemi need?
A: The 5.7L Hemi engine in the 2019 Ram 1500 utilizes a dual-plug design, meaning it requires two spark plugs per cylinder. Since it’s an 8-cylinder engine, you will need a total of 16 spark plugs for a complete replacement.
Q: How often should I change the spark plugs in my 2019 Ram 1500 5.7 Hemi?
A: The recommended interval for changing spark plugs in a 2019 Ram 1500 5.7 Hemi typically depends on the type of spark plug. For copper plugs (less common in modern Hemis), it might be every 30,000 miles. For platinum plugs, around 60,000 miles. However, for the high-performance iridium or ruthenium spark plugs commonly used and recommended for the Hemi, the interval can extend to 100,000 miles or even more. Always consult your vehicle’s owner’s manual for the most accurate and manufacturer-specific maintenance schedule.
Q: What are the symptoms of bad spark plugs in a 5.7 Hemi?
A: Symptoms of failing spark plugs in your 2019 Ram 1500 5.7 Hemi can include: engine misfires (a feeling of hesitation or stumble), rough idling, decreased fuel economy, loss of acceleration or power, difficulty starting the engine, and the illumination of the Check Engine Light on your dashboard. Addressing these symptoms promptly can prevent further engine damage.
Q: Should I replace ignition coils at the same time as spark plugs?
A: For a 2019 Ram 1500 5.7 Hemi, it’s often recommended to consider replacing ignition coils when you replace spark plugs, especially if your truck has high mileage or you’re already experiencing ignition-related issues. Worn spark plugs can put extra strain on ignition coils, causing them to fail prematurely. Replacing both simultaneously, as offered by some of our recommended combo kits, ensures a refreshed, balanced ignition system and can prevent future problems, saving you labor costs down the line.
Q: Are pre-gapped spark plugs suitable for my 2019 Ram 1500 5.7 Hemi?
A: Yes, many high-quality aftermarket spark plugs for the 5.7 Hemi, including some in our list, come pre-gapped to the factory specification (typically 0.044 inches). While convenient, it’s always a good practice to double-check the gap with a feeler gauge before installation, as transit and handling can sometimes alter the gap. Never force the gap adjustment on fine-wire electrodes (like iridium or ruthenium) to avoid damage; instead, gently adjust if needed.
Q: Will changing my spark plugs improve my Hemi’s fuel economy?
A: Absolutely. Worn or fouled spark plugs can lead to incomplete combustion, causing your 2019 Ram 1500 5.7 Hemi to consume more fuel than necessary. By replacing them with new, efficient spark plugs, especially those designed for optimal combustion like iridium or ruthenium plugs, you can restore proper ignition and often see a noticeable improvement in your truck’s fuel economy and overall engine efficiency.
