Complete Buying Guide for 6.7 Cummins Grid Heater Delete Pros And Cons
Deciding whether to perform a 6.7 Cummins grid heater delete is a significant choice for any Ram truck owner. It involves weighing the potential benefits against the challenges, particularly regarding cold-weather starting. This buying guide will walk you through the essential factors to consider, helping you make an informed decision and choose the right supporting products for your truck.
Essential Factors We Consider
When evaluating the 6.7 Cummins grid heater delete pros and cons, several critical factors come into play. Understanding these will help you determine if a delete is suitable for your specific needs and driving conditions.
- ✓ Climate and Cold-Start Requirements: This is arguably the most important factor. The primary purpose of the grid heater is to aid engine starting in cold weather. If you live in a region with consistently freezing temperatures, deleting the grid heater without an adequate alternative (like a robust block heater or upgraded intake heating) will lead to difficult and potentially damaging cold starts. For those in warmer climates, this concern is significantly reduced.
- ✓ Performance Goals: One of the main pros of a grid heater delete is improved airflow to the engine. The factory grid heater element can restrict intake air, especially at higher RPMs, potentially hindering performance. If you’re pursuing maximum horsepower or efficiency through other modifications, removing this restriction can be beneficial. Products like the SPBREW Intake Manifold Kit directly capitalize on this by offering a more open intake design.
- ✓ Reliability Concerns (Dropped Bolts): A notable concern with the factory 6.7 Cummins grid heater is the potential for its retaining bolts to loosen and fall into the engine, causing catastrophic damage. A complete grid heater delete or an upgrade that replaces the entire assembly (like the SPBREW kit) mitigates this risk entirely, offering significant peace of mind.
- ✓ Installation Complexity: Deleting or upgrading the grid heater often involves accessing the intake manifold, which can be a moderately complex task. Consider whether you have the necessary tools and mechanical expertise, or if you’ll need professional installation. The products reviewed emphasize ease of installation, but it’s still a factor.
- ✓ Complementary Upgrades: If you perform a grid heater delete, you must consider alternatives for cold-weather starting. High-quality engine block heater cords are crucial in this scenario, ensuring your engine remains warm. Additionally, considering other reliability upgrades, such as reinforced heater hose connectors, can enhance overall engine integrity during any significant modification.
- ✓ Legal and Emissions Considerations: While most of the products discussed are hardware replacements and not explicit emissions delete components, always be aware of local regulations. Modifying any part of your intake system could theoretically impact emissions, depending on the specific setup and local laws.
Budget Planning
The cost associated with a 6.7 Cummins grid heater delete can vary widely depending on your approach. A simple delete plate might be inexpensive, but it leaves you without cold-start assistance. Comprehensive intake manifold kits that include an upgraded heater, like our Best Choice, will be a larger upfront investment but offer a complete, performance-enhancing solution that also addresses reliability. Budget for quality supporting components too, such as robust block heater cords and durable cooling system connectors, as these are vital for long-term reliability and performance, especially if you’re foregoing the OEM grid heater.
Final Thoughts
Ultimately, the decision to proceed with a 6.7 Cummins grid heater delete should be based on a careful evaluation of your truck’s specific use case, the climate you operate in, and your performance expectations. If you prioritize maximum airflow and wish to eliminate the risk of dropped grid heater bolts, a delete or comprehensive upgrade is a strong consideration. However, always ensure you have a reliable plan for cold-weather starts. Investing in high-quality components, whether it’s an upgraded intake manifold with a new heater, or a dependable block heater cord, is key to maintaining your 6.7L Cummins’ performance and longevity.
Frequently Asked Questions
Q: What is the 6.7 Cummins grid heater for?
A: The 6.7 Cummins grid heater is an electrical heating element located in the intake manifold. Its primary purpose is to heat the incoming air to the engine during cold starts, helping the diesel fuel ignite more easily and ensuring smoother engine operation in freezing temperatures. It essentially functions as a glow plug system for the intake air.
Q: Why do people delete the 6.7 Cummins grid heater?
A: People consider a 6.7 Cummins grid heater delete for several key reasons. Firstly, the factory grid heater can be a source of potential failure, with its retaining bolts sometimes loosening and falling into the engine, leading to catastrophic damage. Secondly, the heater element itself can restrict airflow to the engine, which performance enthusiasts seek to eliminate for improved power and efficiency. Lastly, in warmer climates, the grid heater is often deemed unnecessary.
Q: What are the pros of a 6.7 Cummins grid heater delete?
A: The main pros of a 6.7 Cummins grid heater delete include: improved airflow to the engine, leading to potential gains in horsepower and torque; elimination of the risk of dropped grid heater bolts, preventing catastrophic engine damage; and a cleaner, less restrictive intake manifold design. For those in warm climates, it also removes an unnecessary component.
Q: What are the cons of a 6.7 Cummins grid heater delete?
A: The primary con of a 6.7 Cummins grid heater delete is significantly compromised cold-weather starting capability. Without the grid heater, the engine will struggle to start in freezing temperatures, potentially leading to increased battery drain, starter wear, and a longer cranking time. This drawback necessitates alternative cold-start solutions like an engine block heater or upgraded intake heating systems, especially in cold regions.
Q: Will deleting the grid heater affect my truck’s performance?
A: Yes, deleting the grid heater can affect your truck’s performance, generally positively in terms of airflow. By removing the restrictive heating element, the engine can breathe more freely, potentially leading to slight gains in horsepower and torque, especially at higher RPMs. However, the most significant “performance” impact will be on cold starts, where performance will be severely hampered without an alternative heating source.
Q: Are grid heater deletes legal?
A: The legality of a grid heater delete can vary depending on local environmental regulations and emissions testing requirements. While the grid heater is not directly an emissions control device, modifications to the intake system can sometimes fall under scrutiny. Always check your local and state laws. If a delete involves replacing it with another functional heating system, like an upgraded intake manifold with a new heating coil, it may be more acceptable than a complete removal without any replacement.
Q: What are alternatives for cold weather starting if I delete the grid heater?
A: The most common and effective alternative for cold weather starting after a 6.7 Cummins grid heater delete is an engine block heater. These heaters warm the engine block and oil, facilitating easier starts. Other alternatives include fuel additives designed for cold weather, or in some cases, upgrading to an intake manifold that incorporates a more reliable or vertically mounted heating element, such as some aftermarket kits offer.
Making an informed decision about your 6.7 Cummins grid heater is crucial for your truck’s longevity and performance. Whether you opt for a full delete, an upgrade, or simply bolster your cold-start capabilities with a robust block heater, the products and insights shared here aim to guide you toward the best solution for your diesel powerhouse. Choose wisely, drive safely, and keep your Cummins running strong!
