Improved Racing Low-Profile Oil Cooler Adapter

Improved Racing’s GM LS-series oil cooler adapter’s slim design was developed to provide more header clearance than any other adapter on the market. The mounting holes are counter-bored so the mounting bolts fit flush with the adapter surface, and the included Viton rubber and aluminum gasket is recessed into the adapter for maximum clearance with a reliable seal.

The adapter features two 1/8″ NPT ports for sensors or a turbo oil supply line. It is machined from a single piece of billet 6061-T6 aluminum and is black anodized. The adapter features standard female -08AN O-ring boss ports for optional anodized adapter fittings in your choice of -8AN, -10AN or -12AN lines. Can be mounted upside down on the 5th generation Camaro / G8 oil pan for additional header clearance.

The optional 1/8″ NPT temperature sensor for the 1997-2004 Chevrolet Corvette (C5), part number LC5-100, allows you to retain the functionality of the factory oil temperature gauge. The sensor features an extended pigtail with a factory connector and is 100% plug-and-play with the factory wiring harness. This retains the functionality of the factory C5 Corvette oil temp gauge exactly as stock.

Old part number EGM-1006.

Installation Notes

• Note: This oil adapter is designed for O-ring boss fittings with a straight thread length of 0.500″ or less. We recommend using our fittings in order to guarantee proper fitment and seal.
• Corvette motor mounts: We recommend using a 90-degree AN fitting on the top port and a 90-degree AN fitting on the front (angled) port to connect the oil lines to this adapter.
• F-Body motor mounts: We recommend using a 90-degree AN fitting on the top port and a 60-degree AN fitting on the front (angled) port to connect the oil lines to this adapter.
• Gen IV LS Engines: On some engines, the knock sensor is located above the oil cooler adapter. You may need to loosen and rotate the knock sensor slightly, and unbolt and move the knock sensor wiring harness out of the way to clear the oil lines.
