Jetprime PAIR Circuit Eliminator Cover for Kawasaki Ninja ZX-4R ZX-4RR
The secondary air injection system (PAIR) routes fresh air from the airbox to the exhaust system in order to aid the combustion of unburned fuel in the exhaust. This system is designed to improve emissions on stock exhaust systems, but will cause exhaust popping and backfiring when you fit aftermarket exhausts. The CNC machined plate replaces the original cover and the rubber cap closes the hole in the filter box.
