Great Product
Simple to install and works great. Decel pop is gone.
This replacement cap is designed for use with Brock’s Performance exhaust systems to block off the PAIR (Pulsed Secondary Air Injection) system. By eliminating unwanted air from entering the exhaust, it helps prevent ‘deceleration pop’ and maintains proper ram-air pressure in the airbox for consistent performance.
Simple to install and works great. Decel pop is gone.
Easy way do block off air through Pair Valve and get more accurate AFR readings for my Woolich Racing data logger. Somewhat easy to install.
This was a great and simple product to use. Great for easy to install.
