It cools exhaust gases before they are recirculated into the intake, reducing combustion temperatures and nitrogen oxide (NOx) emissions. The kit includes the cooler assembly and necessary gaskets or seals. It is typically replaced when the cooler fails due to clogging, cracking, or internal coolant leaks, which can cause coolant loss, white smoke, or overheating.
