Product Description

Low Profile Oil Cooler Adapter for LS-Series Engine

Our GM LS-series oil cooler adapter is designed to provide more header clearance than any other adapter on the market. The angled cutout makes it nearly 0.5" slimmer where headers typically interfere. We eliminated the aluminum gasket and replaced them with Viton o-rings, which provides additional clearance while still ensuring a reliable seal. The mounting holes are counter-bored so the mounting bolts fit flush with the adapter surface.

The adapter features two 1/8" NPT ports for oil pressure and oil temperature sensors, or for a turbo oil supply line. It is machined from a single piece of 6061-T6 aluminum and is black anodized. Includes anodized o-ring adapter fittings for -10AN or -8AN lines (your choice).
