HPD Special Parts RA7 EGR Cooler Delete Plates are a clean, high-performance solution to block off the factory EGR system on 4JJ1 engines. Whether you’re chasing better throttle response, reliability, or prepping for an upgraded turbo, these plates are a must-have for your RA7 build.
*Check your EGR setup — suits the single cooler layout (not 2-bolt or 3-bolt types).
Will this fit my RA7?
It suits the single-cooler EGR layout used on RA7 4JJ1 (and ~2009 Colorado 4JJ1). Check yours isn’t the 2-bolt or 3-bolt type.
Do I need a remap?
We strongly recommend an ECU remap (or a purpose EGR delete harness) to avoid fault codes and ensure correct engine management.
Is this legal for road use?
These plates are intended for off-road and motorsport applications only. Check your local laws and regulations.
