- Not legal for sale or use on pollution-controlled vehicles in California, Colorado, or Arizona.
- These parts are for off-road or competition use only.
- Check local and federal laws before purchasing.
- A: Yes. The ECU will detect the missing EGR components. A mandatory ECU tune is required post-installation to disable the related sensors and prevent fault codes. Driving without a tune is not advised.
- A: Smoke output is a function of tuning, not the hardware itself. A proper, professional-grade tune will optimize the air-fuel ratio, often resulting in cleaner exhaust. Smoke issues are typically a sign of poor tuning.
- A: Users report significant improvements: reduced engine bay temperatures, smoother throttle response, and enhanced towing stability. A minor increase in fuel economy is also commonly observed due to improved engine efficiency.
- A: No. Correctly installed, an EGR delete protects the engine by eliminating soot recirculation, which prevents carbon buildup in the intake and combustion chambers. This enhances engine longevity and operational smoothness.
