Description

This race plug works by completely blocking the pressure relief port to maintain optimal fuel rail pressure during full-throttle driving. It addresses issues where the factory pressure relief valve can leak, causing a drop in fuel pressure and triggering diagnostic trouble codes (DTCs) like P1093 or P0087. By eliminating this leak, the plug ensures consistent fuel delivery for maximum power and efficiency.
