Improved Racing's EGM-115 oil cooler block-off cover plate installs over the oil cooler ports found on some GM Gen V small-block (LT series) oil pans.

This adapter has two -8 O-Ring boss ports plus one 1/8" NPT sensor port. The -8 ORB ports can be used with up to -12AN lines to feed an oil accumulator or turbos. Optional -8 ORB sensor adapter plugs are offered for both 1/8" NPT threads and M12 threads.

The bypass cover is CNC-machined from billet 6061-T6 aluminum and Type II anodized in black. It features a large ported internal cavity with smooth features to improve flow characteristics when compared to the factory diecast bypass cover. One -8 O-ring boss plug and one 1/8" NPT plug are both included for unused ports.
