A truck owner with a 6.7 Cummins engine should consider removing their grid heater for achieving better fuel efficiency while gaining increased power and smoother performance. A stock grid heater functions to aid cold start air heating yet its presence restricts airflow and negatively affects engine performance. Replacing your stock 6.7 Cummins grid heater with a delete option provides better airflow and additional horsepower while optimizing engine performance.
Why Should You Remove the Grid Heater?
The stock grid heater positioned in the intake system builds turbulence through airflow limitations that harm combustion operation. Installing the SPELAB 6.7 intake horn as a high-flow substitution for the stock grid heater brings your engine unimpeded fresh air. The enhanced engine performance comes from improved combustion quality together with better fuel atomization which leads to greater power production. You will experience improved throttle feedback after installing the part. This improves both daily driving and heavy towing capabilities.
Risks of Keeping the Stock Grid Heater
One big problem with the factory-installed grid heater is carbon buildup. Over time, deposits collect on the heater elements, and pieces can break off, falling into the engine. This can cause serious damage, like piston scoring and valve failure. By installing a 6.7 Cummins grid heater delete, you reduce this risk and improve the engine’s reliability and lifespan.
Why Upgrade the Intake Manifold?
Pairing a grid heater delete with an upgraded intake manifold is a game-changer. The stock intake manifold has design restrictions that limit airflow. Upgrading to a high-performance SPELAB 6.7 Cummins intake manifold upgrade allows for smoother, more consistent air delivery. This means more power, reduced turbo lag, and better efficiency.
The Advantages of a 3.5” Intake Manifold
Many truck owners upgrade to a 3.5” intake manifold because it allows maximum airflow without excessive turbulence. A larger plenum and smoother internal design improve engine breathing, leading to better power and fuel efficiency. It also helps keep intake air cooler, reducing heat soak and ensuring denser air for better combustion.
The Role of the SPELAB 6.7 Intake Horn
The SPELAB 6.7 intake horn is an essential part of improving your intake system. It creates a smooth, direct airflow path into the engine, eliminating restrictions that hurt performance. Built from high-quality materials, this intake horn is durable and long-lasting, even under extreme conditions. It also reduces turbulence in the intake system, making the engine run more smoothly and efficiently.
Turbo Efficiency and Fuel Savings
After removing the grid heater and improving the intake manifold performance your turbo system becomes more efficient. The turbocharger reaches its maximum speed more quickly because of improved airflow resulting in speedier acceleration and enhanced towing abilities. Heavy load towing will benefit significantly from implementing this modification.
Better airflow also means better fuel economy. Since the engine burns fuel more efficiently, you’ll get more miles per gallon. Many truck owners report fuel savings after installing a 6.7 Cummins grid heater delete and an upgraded intake manifold. With diesel prices rising, even small efficiency gains can lead to big savings.
Installation and Compatibility
The installation of the 6.7 Cummins grid heater delete with intake manifold upgrade can be completed by DIY individuals who possess basic tool skills. Secure all connections and ensure a proper seal fits over the intake system to stop leakage. Before modifying your engine you should verify compliance with local emissions laws because certain areas enforce strict regulations.
Keeping Your Intake System in Top Shape
To keep your intake system working at its best, regular maintenance is key. Check and clean the intake components frequently to prevent dirt buildup that can reduce performance. Inspecting the intake manifold and SPELAB 6.7 intake horn regularly ensures everything stays in peak condition.
Conclusion
A combination of 6.7 Cummins grid heater deletion and upgraded intake manifolds provides better performance with enhanced power output and fuel efficiency and smooth engine operation. Using a SPELAB 6.7 intake horn combined with a 3.5” intake manifold will lead to notable performance gains. These truck modifications deliver worthwhile improvements for enhanced towing ability together with fuel economy benefits and improved truck operation.
FAQs
What does a grid heater do in a 6.7 Cummins engine?
It preheats incoming air for cold starts but can also restrict airflow and reduce performance.
Will my truck struggle to start without a grid heater?
In very cold climates, a grid heater helps, but most truck owners find their engines start just fine without it.
Do I need a 3.5” intake manifold for a grid heater delete?
It’s not required, but it maximizes airflow and improves performance when paired with a grid heater delete.
Will I get better fuel economy with a grid heater delete?
Yes, since removing restrictions improves airflow and combustion, leading to better fuel efficiency.
Is it legal to delete the grid heater?
Laws vary by region, so check local regulations before modifying your truck.
By making these simple upgrades, you’ll unlock more power, efficiency, and reliability from your 6.7 Cummins engine!
