Eliminate unnecessary components and unlock more precise tuning with Brock’s Performance PAIR Block Off Plates. Designed to replace the factory PAIR (Pulsed Secondary Air Injection) system, these CNC-machined plates seal off the air injection ports on the cylinder head, preventing fresh air from entering the exhaust stream.

By removing the PAIR system, you gain more accurate air/fuel ratio readings—essential for tuning—and reduce “decel popping” commonly caused by unburned air igniting in the exhaust. Whether you're chasing horsepower or just cleaning up your engine bay, this kit delivers the performance and weight savings racers demand.
