0.039" Copper Exhaust Manifold Gasket

The SpeedFactory Racing Precision Fit Exhaust Manifold Gasket (SF-02-251) is engineered to provide a reliable seal for B-Series and K-Series engine applications. This gasket is specifically tailored for K-Series engines, with fitment confirmed for K20a, K24A, and K20z engines produced between the 2002 and 2011 model years. The precision-fit design from SpeedFactory Racing aims to streamline installation and ensure optimal performance. For best results, it is recommended to re-torque the exhaust manifold after the first heavy heat cycle once the engine has cooled. This step is crucial to ensure continued sealing and prevent potential exhaust leaks after initial installation and break-in.
