FAQ

Q: Is installation complicated?

A: This product is designed for direct replacement without additional modifications. However, users with basic mechanical skills or professional technicians are recommended for installation. Specialty tools may be helpful but are not required for most installations.

Q: Does this affect the vehicle's warranty?

A: This is an aftermarket modification part, which may affect your vehicle’s factory warranty. It’s advisable to consult with your car manufacturer or a certified technician regarding warranty coverage.

Q: What usage scenarios are best suited for this?

A: Ideal for high-temperature, heavy-load situations, especially for Duramax users who require reliable performance in towing or off-road environments. This kit is specifically beneficial for engines exposed to prolonged operation under heavy strain.

Q: Does this kit include all necessary installation components?

A: Yes, the kit includes all essential components required for installation, ensuring you have everything needed to complete the setup.

Q: What's the average install time for the EGR plate cooler and throttle valve delete kit?

A: Typically 1-4 hours, installation time based on proficiency.

Q: By doing the EGR delete, will my check engine light come on or stay on? If so, what else is needed to turn off the engine light?

A: Installing this kit may trigger error codes related to vehicle deletion adjustments. However, any adjustment that involves deletion of the vehicle can result in throwing a trouble code, and if a CEL occurs, you can use a tuner or other device to clear or block the associated error code.

Q: Will installing this kit void my vehicle's warranty?

A: Using this product may void your vehicle's warranty. Please confirm with your vehicle manufacturer before purchasing and installing this kit.

Q: Is the EGR delete kit worth it?

A: One of the main benefits of an EGR delete is improved performance. The Exhaust Gas Recirculation system is known to cause carbon buildup in the intake manifold and reduce airflow to the engine. Deleting the EGR system reduces carbon buildup and improves airflow to the engine.

Q: Do you get more HP with EGR delete?

A: Deleting or disabling your EGR is unlikely to add horsepower because it only provides a slight change to the air contents of your engine's combustion chambers. While EGR deletes do provide a purer air-fuel ratio, the difference is minor, and any horsepower gains will be small -- likely in the range of 0-5 HP.
