Best Killer Grid Heater Upgrade Kit Dodge/Ram 6.7L Cummins

The killer grid heater upgrade kit for Dodge/Ram 6.7L Cummins trucks is a crucial modification for enhancing performance and reliability, especially in colder climates. This upgrade replaces or modifies the restrictive factory grid heater,leading to improved airflow,increased horsepower,and faster engine starts. It’s a valuable upgrade for owners seeking to maximize their Cummins engine’s potential.

Key Features Analysis

The killer grid heater upgrade kits typically feature several key components and design enhancements.

Larger diameter Intake horn: The upgraded intake horn boasts a significantly larger diameter compared to the stock unit.

This increased diameter allows for a substantial increase in airflow to the engine, reducing restriction and improving overall performance. The larger volume of air translates to better combustion efficiency and increased horsepower, especially at higher RPMs.Furthermore, many aftermarket intake horns include smoother internal contours to minimize turbulence, further optimizing airflow.High-Flow Grid Heater Element: Many kits include a redesigned grid heater element with a more efficient heating pattern and reduced restriction.The high-flow grid heater element is designed to provide optimal cold-weather starting performance while minimizing airflow obstruction. The improved heating pattern ensures quicker and more uniform heating of the intake air,resulting in faster and more reliable engine starts in cold conditions. Furthermore, the reduced restriction allows for less pressure drop across the grid heater, contributing to improved engine efficiency and power output.

Heavy-Duty Construction: These kits are typically manufactured from high-quality materials such as cast aluminum or stainless steel for enhanced durability.The heavy-duty construction ensures that the kit can withstand the harsh conditions of the engine habitat, including high temperatures, pressures, and vibrations. The use of durable materials like cast aluminum or stainless steel provides excellent corrosion resistance and long-lasting performance. The robust design of these kits ensures that they can handle the demands of both stock and modified Cummins engines.

Relocation or Deletion Options: Some kits offer the option to relocate the grid heater or delete it entirely for maximum airflow.

Relocating the grid heater can often improve airflow and simplify maintenance. Deleting the grid heater is a more extreme option, typically chosen by performance enthusiasts in warmer climates where cold-weather starting is not a concern. Deleting the grid heater results in the most important gain in airflow, but it also eliminates the cold-start assistance provided by the grid heater. Drivers in northern climates need to consider that the lack of grid heater assistance might result in greater white, unburned fuel smoke on startup.Complete Installation Hardware: These kits usually come with all the necessary hardware for a straightforward installation process.

The inclusion of all necessary hardware,such as bolts,gaskets,and wiring connectors,ensures a seamless and hassle-free installation,reducing the time and effort required to complete the upgrade. Detailed instructions are frequently enough included as well, guiding the installer through each step of the process. The complete installation hardware makes the upgrade accessible to both experienced mechanics and DIY enthusiasts.

Core Benefits

The benefits of installing a killer grid heater upgrade kit are numerous and can significantly improve the performance and reliability of your Dodge/Ram 6.7L Cummins.

Improved Cold Weather Starting: The high-flow grid heater element provides faster and more reliable engine starts in cold conditions. This reduces wear and tear on the starter and battery, extending their lifespan. For those living in areas with harsh winters, this benefit alone can make the upgrade worthwhile.

Increased Horsepower and Torque: By reducing airflow restrictions in the intake system, these kits can unlock additional horsepower and torque. The larger intake horn and high-flow grid heater element allow the engine to breathe more efficiently, resulting in improved combustion and increased power output. Many users report noticeable gains in throttle response and overall performance after installing the upgrade.

Enhanced Fuel Efficiency: Improved airflow and combustion efficiency can lead to better fuel economy. While the gains may not be dramatic,they can add up over time,especially for those who drive their trucks frequently.This can definitely help offset the initial cost of the upgrade kit.

Reduced EGTs (Exhaust Gas Temperatures): With improved airflow,the engine runs cooler,lowering exhaust gas temperatures (EGTs). Lower EGTs reduce the risk of engine damage, especially when towing heavy loads or running performance modifications. This added protection helps maintain the longevity and reliability of the Cummins engine.

FAQs Section

Will this kit improve my fuel mileage?
While not the primary goal, improved airflow and combustion efficiency can contribute to a slight increase in fuel mileage. The magnitude of the enhancement can vary based on driving habits,vehicle modifications,and environmental conditions,but generally,users report a modest increase in fuel economy.

Can this kit be installed by a novice mechanic?
The installation difficulty can vary depending on the specific kit and the mechanic’s experience. Some kits are designed for straightforward installation with detailed instructions, while others may require more specialized tools and knowledge. most find it easiest to have a professional diesel mechanic complete the installation.

Does this upgrade require custom tuning?
While not always necessary, custom tuning can maximize the benefits of a killer grid heater upgrade kit. Tuning can optimize the engine’s performance to take full advantage of the increased airflow and reduced restrictions. Generally, tuning is done to take full advantage of several bolt on upgrades to optimize them for one another.

is this kit compatible with my aftermarket turbocharger?
compatibility with aftermarket turbochargers depends on the specific design of both the killer grid heater upgrade kit and the turbocharger. Most kits are designed to be compatible with a wide range of turbochargers, but it’s always best to verify compatibility before purchasing. some larger turbocharger setups may require custom modifications to ensure proper fitment.
