Improved Racing Oil Cooler Adapters

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

Enginetech Engine Expansion Plug Kits

Enginetech offers engine expansion plug kits for a variety of car, truck, SUV, high performance, and marine applications. Machined from brass or steel, the kits include a variety of sizes to seal whatever ports need to be closed off. The plugs are produced in accordance with factory specs to ensure proper fit and performance. They meet or exceed OE quality standards. Order the kit recommended for your engine. Expansion plugs (or freeze plugs) serve two primary purposes: to block coolant leaks from internal passages, and to protect the engine block from cracking if the coolant inside freezes and expands. The plugs are designed to "pop out" under the pressure of expanding ice, preventing more severe damage, like a cracked block.
