Earl's Performance Sandwich Filter Adapter

Earl's Performance Sandwich Filter Adapters provide a simple, reliable solution for integrating an oil cooler into virtually any engine build — all while keeping the stock oil filter in its original location. By sandwiching between the engine block and the existing spin-on oil filter, these adapters tap into the engine's oil circuit without requiring permanent modifications.

Key Features:

• Installs between the engine block and the existing spin-on oil filter, preserving the stock filter location
• Routes engine oil through an external oil cooler for improved thermal management
• Constructed from lightweight aluminum with a durable anodized finish
• Available in multiple thread sizes and port configurations to suit a wide range of engine applications
• Select variants include a built-in oil thermostat to regulate oil temperature and promote quick warm-up
• Designed for quick and easy installation with no permanent engine modifications required
• Legal for use on emissions-controlled, non-emissions-controlled, and racing-use vehicles
