High-performance and racing GM LS engines must have the factory-installed Active Fuel Management (AFM) and/or Variable Valve Timing (VVT) systems deleted to maximise power.

However, when these systems are removed, excess oil is pumped through the engine, resulting in over-pressuring and possible damage to engine components.

The Summit Racing™ Oil Pan Pressure Relief Valve Plug for GM LS fixes this by plugging the secondary pressure relief valve built into the oil pan.

The Allen-head style aluminium plug features M14 x 1.5 threads and a black anodised finish. An aluminium crush washer ensures a proper seal.
