Oil Filter Sandwich Adapter - 3/4-16

The MOROSO Oil Filter Sandwich Adapter with 3/4-16 center thread is an essential component for any enthusiast building a custom engine bay or upgrading an existing lubrication system. This adapter serves as the bridge between your engine block and remote oil filtration setups, allowing you to relocate the filter away from the engine for improved accessibility, better cooling airflow, and cleaner engine compartment aesthetics.

Engineered with precision, the 3/4-16 thread specification is the industry standard for most modern engine blocks and filter head assemblies, ensuring compatibility across a wide range of platforms without modification. The sandwich design allows pressurized oil to flow from the block through the adapter into external filter canisters, oil coolers, or auxiliary filtration equipment, then back to the engine—all while maintaining proper pressure retention and preventing leaks.

At just 1.15 lbs and measuring 3.95 x 2.85 x 5.1 inches, this adapter is compact enough to fit tight engine bays while offering robust internal passages that support full flow rates without restriction. Mechanics and engine builders gravitate toward MOROSO for their reliability and performance, making this adapter ideal for street and track applications alike.
