Improved Racing oil cooler adapters have a low-profile for more header clearance. The adapters are machined from a single piece of billet aluminum and black anodized. For additional clearance with reliable sealing, they come with aluminum gaskets fitted with Viton® seals, and the adapter mounting holes are counter-bored so the mounting bolts fit flush with the adapter surface. Select Improved Racing oil cooler adapters are also available with a built-in thermostat. Oil coolers help prevent the oil from getting too hot, but are also prone to lowering oil temperatures too much, especially in colder weather or during highway driving. The rebuildable thermostat speeds warm-up and helps reduce engine wear and horsepower losses by preventing oil temperatures from dropping below optimal levels. Features and benefits * 100 percent bolt-on solution; no fabrication, bending, or line modification is required * Viton® seals throughout for maximum reliability * Oil exiting the adapter is filtered oil * 6061 T-6 billet aluminum construction with black MIL-A-8625 Type II anodized finish * Standard female -8 AN O-ring boss threads for optional anodized adapter fittings in your choice of -8 AN, -10 AN, or -12AN lines * Depending on application, includes port(s) for oil sensors or turbo oil supply * Includes all necessary hardware * Limited lifetime warranty
