6.7 Cummins Throttle Valve Delete

A 6.7 Cummins throttle valve delete is a performance upgrade for diesel engines that removes the factory electronic throttle body and replaces it with an adjustable cable system. This allows the engine to run more efficiently by eliminating restrictions caused by the factory system, increasing air flow into the engine and providing improved power, torque, and fuel economy. The delete is relatively easy to install but should only be done by experienced mechanics or persons familiar with automotive systems in order to avoid damaging other parts of your vehicle’s powertrain.

The 6.7 Cummins Throttle Valve Delete is an innovative new product that can help improve the performance of your diesel engine. By removing the throttle valve, it allows for greater airflow and better fuel economy while also improving acceleration response time and increasing power output. This product is easy to install and eliminates the need for a full exhaust system upgrade and other expensive modifications, making it perfect for those looking to get more out of their truck without breaking the bank.

What are the Benefits of a Throttle Valve Delete 6.7 Cummins?

A throttle valve delete for a 6.7 Cummins diesel engine offers several benefits that should not be overlooked. By removing the factory restrictive and inefficient electronic variable geometry turbo (E-VGT) from your truck, you can improve performance significantly while still maintaining reliability and fuel economy. Not only will it reduce turbo lag, allowing your truck to respond quicker when accelerating or passing, but it will also boost power output through reduced back pressure in the exhaust system.

Additionally, this upgrade improves airflow into the engine as well as out of it by eliminating a major restriction point – resulting in improved overall efficiency and torque production across the entire RPM range. Finally, a throttle valve delete is quite cost effective compared to other performance upgrades and can be done relatively quickly with minimal effort at home or by any qualified mechanic shop/garage.

How Does a Throttle Valve Work on a 6.7 Cummins?

A throttle valve on a 6.7 Cummins engine works to regulate how much air enters the engine cylinders and is an important part of the fuel injection system. The throttle valve opens when you press down on the accelerator pedal, allowing more air into the intake manifold, which increases combustion pressure inside the cylinder for higher power output. Inside the throttle valve there is a butterfly-shaped plate that rotates along its axis when it receives signals from sensors in response to your accelerator inputs.

As this plate moves, it either restricts or allows more airflow through its opening – thus controlling engine speed and power output accordingly. The other components involved in this process are the idle control motor, which assists with maintaining consistent idle speeds; and Electronic Control Unit (ECU), which collects data from various sensors throughout your vehicle’s systems and sends control signals to different actuators such as electric motors or solenoids found within modern engines like your 6.7 Cummins. When all these pieces work together properly, they help ensure optimal performance of your diesel truck by ensuring ample amounts of oxygen enter into each cylinder for maximum efficiency during acceleration and deceleration alike!

What Does a Throttle Valve Kit Do?

A throttle valve kit is an extremely important piece of equipment for a car’s engine. It plays a critical role in controlling the amount of fuel and air mixture that enters the combustion chamber. The throttle valve works by controlling the opening and closing of valves which regulate the flow of air and fuel into each cylinder.

This allows drivers to adjust their speed, accelerate faster or slower, as well as control how much power they are getting from their engine at any given time. With this level of control over your vehicle’s performance, you can be sure to get optimal output while still maintaining safety on the road. Additionally, with proper installation and maintenance, a throttle valve kit can help extend the life of your vehicle’s engine by ensuring that it gets only clean air and fuel at all times.

What is a Throttle Valve on a Cummins?

A throttle valve on a Cummins engine is an important component of the fuel system. It controls the amount of air that enters the intake manifold, providing precise control over how much power is produced from each cylinder. The throttle valve opens and closes in response to changes in engine speed or load conditions, allowing for greater performance and efficiency.

It also helps keep emissions low by controlling combustion timing, which reduces unburned fuel particles entering the environment. On newer models of Cummins engines, this part can be electronically controlled via software or hardware depending on the model. This makes it easier to adjust settings precisely without needing any additional tools or manual adjustments, giving you improved performance with less maintenance required overall.

Throttle Valve Delete Pros And Cons

Throttle valve deletes are a popular upgrade for car enthusiasts who want to improve the performance of their vehicles. While there are some potential positives associated with this modification, such as increased horsepower and torque, it can also have negative impacts, such as decreased fuel efficiency and potentially more wear and tear on your engine components. Ultimately, whether or not you decide to delete your throttle valve will depend on what type of performance modifications you’re interested in making and how much risk you’re willing to accept.

6.7 Cummins Throttle Valve Sticking

If you drive a 6.7 Cummins diesel engine, you may have experienced the throttle valve sticking. This problem can cause poor acceleration and performance issues when it occurs, as the throttle plate will not open or close properly due to debris buildup in the bore of the throttle body. To fix this issue, it is important to clean out all of the deposits from inside of your intake manifold and also use a high-quality oil filter for regular maintenance.

Additionally, if there are any vacuum leaks present then these should be addressed immediately in order to prevent further problems with your vehicle’s throttle valve operation.

6.7 Cummins Throttle Valve Delete Instructions

If you’re looking to increase your 6.7 Cummins’ performance and fuel economy, a throttle valve delete can be an effective solution. This procedure requires removing the factory electronic governor system, making sure all hoses are properly routed and connected, and installing a manual throttle linkage in place of the automatic one that was removed. It’s important to have the right tools on hand as well as a good understanding of how your engine works before attempting this modification – make sure you read up on all instructions thoroughly before getting started!


Overall, the 6.7 Cummins Throttle Valve Delete is a great option for those looking to improve their vehicle’s performance and increase its overall efficiency. Not only does it provide an easy installation process with minimal modifications required, but it also eliminates the need for extra parts such as the EGR cooler, making your vehicle more reliable and cost-effective in the long run. Furthermore, this modification can help reduce emissions while still providing impressive power gains that make driving more enjoyable.
