Derale Performance Universal Thermostatic Sandwich Adapter

The Derale Performance Universal Thermostatic Sandwich Adapter lets you add an engine oil cooler without relocating the factory oil filter. It is a thermostatic oil filter sandwich adapter, also sold as an oil cooler adapter or oil filter adapter kit. It installs between the stock oil filter landing and the oil filter. It provides external oil line ports for plumbing in a cooler, and the stock filter stays in place.

Key Features:

• Thermostatic design with a 180°F thermostat that diverts oil from the cooler until the oil reaches operating temperature
• Cast from high quality aluminum
• Provides external oil lines for oil coolers without relocating the factory oil filter
• 3/8" NPT ports for connecting oil cooler lines
• Keeps a factory-equivalent oil filter in use
• Universal design that covers multiple common oil filter thread sizes (see each part number for the exact thread sizes it supports)
• Includes the sandwich adapter, sleeve nuts and O-rings, as documented for each part number

These adapters are a straightforward way to add oil cooling to street, performance, towing and racing engines. Because the factory filter is retained, installation is simple and the filter stays easy to service.
