2. SPELAB 6.7 Cummins Grid Heater Delete | Key Benefits

The SPELAB 6.7 Cummins Grid Heater Delete is a highly effective upgrade designed to improve the performance of 2007-2024 RAM 2500/3500 trucks equipped with the 6.7L Cummins engine. By removing the restrictive factory grid heater, this upgrade offers several performance and efficiency benefits, making it an essential modification for diesel enthusiasts who seek improved reliability and enhanced airflow.

2.1 Enhanced Airflow and Lower Intake Temperatures

One of the most significant advantages of the SPELAB Grid Heater Delete is the substantial improvement in airflow. The stock grid heater often acts as a bottleneck in the intake system, restricting the flow of air and leading to increased intake temperatures. By removing this component, the Grid Heater Delete allows for a much freer flow of air into the engine.

As a result, lower intake temperatures are achieved, which in turn enhances combustion efficiency. Cooler, denser air entering the cylinders leads to a more complete burn, producing more power and improving fuel efficiency.

This is particularly beneficial for high-performance applications or when the engine is under heavy load, as it allows the engine to operate more efficiently and with greater power output.

2.2 Electrical Load Reduction

In addition to improving airflow, the Grid Heater Delete reduces the electrical load on your vehicle’s system. The factory grid heater requires a significant amount of power to function, especially during cold starts. By eliminating this component, you free up electrical capacity, which can reduce strain on your battery and alternator, resulting in a more reliable electrical system overall.

This reduction in electrical load not only extends the life of your vehicle’s electrical components but also lowers the risk of issues arising from excessive power draw. For those who use additional electrical accessories or have upgraded systems in their vehicle, this upgrade can be particularly beneficial.

2.3 Simplified and Cleaner Engine Bay

Another key benefit of the Grid Heater Delete is the simplified layout it creates within the engine bay. Removing the grid heater eliminates an unnecessary component, resulting in a cleaner, more organized engine bay. This not only makes maintenance and repairs easier but also enhances the overall appearance of the engine compartment.

The SPELAB Grid Heater Delete is crafted with a sleek, anodized finish, which adds a touch of style to your engine bay. Whether you're a performance enthusiast or someone who takes pride in a well-organized and visually appealing engine setup, this upgrade enhances both form and function.

3. SPELAB 6.7 Cummins Intake Manifold | Performance Upgrades

The SPELAB 6.7 Cummins Intake Manifold is engineered to maximize airflow and improve overall engine performance in RAM 2500/3500 trucks equipped with the 6.7L Cummins engine. By significantly enhancing the volume of air that reaches the cylinders, this intake manifold offers substantial power gains, especially for diesel enthusiasts looking to boost engine output and efficiency.

3.1 Airflow (CFM) and Mass Air Flow (MAF) Comparison

A key performance indicator of an intake manifold is its ability to increase CFM (Cubic Feet per Minute) and Mass Air Flow (MAF), which directly affect how much oxygen the engine receives for combustion. The SPELAB 6.7 Cummins Intake Manifold far surpasses the stock manifold in terms of airflow capacity, delivering a significant upgrade for those seeking to enhance engine performance.

• SPELAB New Intake Manifold: Delivers an impressive 897 CFM, allowing optimal airflow into the engine. This level of airflow enables the engine to breathe freely, particularly when paired with an EGR delete kit, resulting in maximum engine performance.
• 5" Budget Intake Manifold: Offers 487 CFM, providing a solid improvement over stock for those looking for a more budget-friendly performance boost.
• OEM (Stock) Intake Manifold: The factory intake manifold provides only 421 CFM, significantly limiting airflow and restricting engine potential, especially under heavy load conditions.

In terms of MAF:

• SPELAB Intake Manifold: Achieves a MAF rate of 7 lbs/min, delivering the most oxygen for combustion, which maximizes horsepower and fuel efficiency.
• 5" Budget Intake Manifold: Provides 43.5 lbs/min, offering a moderate performance improvement for daily drivers.
• OEM Manifold: With a MAF rate of 6 lbs/min, the stock manifold limits the engine’s ability to reach its full potential, particularly during high-performance driving.

3.2 High Performance Under Heavy Load

The SPELAB 6.7 Cummins Intake Manifold is designed to excel under demanding conditions, making it the ideal choice for drivers who frequently operate their vehicles under heavy load or in high-stress environments.

By significantly increasing the amount of air available for combustion, this manifold ensures that your engine performs optimally, even during towing, off-roading, or other high-performance applications.

The increased airflow not only boosts horsepower but also improves fuel efficiency, allowing for better throttle response and smoother power delivery.

This makes the SPELAB Intake Manifold a perfect upgrade for those looking to enhance both everyday drivability and heavy-duty performance.

3.3 Compatibility with Other Performance Upgrades

The SPELAB Intake Manifold is fully compatible with other key performance upgrades, such as an cold air intake systems, and high-flow exhaust systems. When used in combination with these upgrades, the intake manifold can unlock even more power and efficiency, making it a critical component in any performance build.

It’s the ideal choice for those who want to take their vehicle’s performance to the next level.

4. How SPELAB Intake Manifolds Improve Your 6.7L Cummins

The SPELAB 6.7 Cummins Intake Manifold is designed with advanced engineering principles that significantly improve airflow and engine efficiency. By focusing on key aspects like the shape, size, and configuration of the plenum and runners, SPELAB has created an intake manifold that maximizes engine performance across a wide RPM range.

Here’s how the design elements work to enhance your engine's output and reliability.

4.1 Optimized Design for Maximum Airflow

At the heart of the SPELAB Intake Manifold’s performance gains is its plenum and runner design, which have been specifically optimized for maximum airflow. The plenum acts as a reservoir for air, allowing it to be distributed evenly across all cylinders. This design ensures that each cylinder receives the same amount of air, preventing any uneven distribution that could result in engine knock or reduced performance.

The runners are responsible for carrying air from the plenum to the intake ports on the cylinder head.

SPELAB’s intake manifold features wider and smoother runners compared to the stock manifold, which reduces airflow resistance and minimizes pressure drops. This ensures that the engine gets a consistent supply of high-pressure air, leading to better combustion and higher power output, particularly during heavy load or high RPM scenarios.

4.2 Variable Length Intake Runners for Broader RPM Range

One of the standout features of high-performance intake manifolds like the one offered by SPELAB is the use of variable length runners.

These runners are designed to deliver optimal airflow across a wide range of engine speeds. For lower RPMs, longer and narrower runners help maintain the velocity and turbulence of the air, improving combustion efficiency at low speeds and increasing torque.

At higher RPMs, shorter and wider runners are more effective, as they allow more air to flow into the engine quickly, maximizing power. This dynamic design ensures that your engine performs well whether you are towing a heavy load at low speeds or pushing the engine to its limits at high speeds.

SPELAB’s intake manifold is designed to harness the benefits of Helmholtz resonance—a principle that uses air pressure waves to “supercharge” the engine during the intake cycle.

By timing the length and width of the runners to the engine’s RPM, the manifold can send air into the cylinders more efficiently, resulting in a power boost that mimics the effects of a low-pressure supercharger.

Now that you've explored how these upgrades can improve your 6.7 Cummins, take the next step toward transforming your engine’s performance with SPELAB’s innovative products.
