Oil Filter Adapter, Sandwich Style

OVERVIEW

Heat is the primary enemy of the air-cooled flat-four engine, and managing it effectively is the difference between a long-lasting power plant and a premature rebuild. Whether you are trekking through the Mojave in a Class 5 Baja Bug or hauling a full camping load in a late-model Westfalia, maintaining consistent oil viscosity is paramount to protecting your bearings and valvetrain. The EMPI Sandwich Style Oil Filter Adapter provides a high-performance, bolt-on solution for enthusiasts looking to integrate an external oil cooler into their lubrication system without the permanent commitment of drilling and tapping the engine case for a traditional full-flow setup. By mounting directly between your existing oil filter mount and the spin-on filter, this adapter acts as a high-flow bypass, diverting oil to your cooler of choice before returning it to the engine, ensuring your internals stay lubricated with chilled oil even under the most demanding thermal conditions.

Crafted with the precision and durability that EMPI is known for in the Volkswagen community, this adapter is engineered for maximum flow with minimal pressure drop. The unit features two 3/8 NPT ports, allowing for a wide variety of plumbing options, from braided stainless steel lines to high-pressure rubber hoses. This is the ideal upgrade for VW Type 4 engines found in later Buses and Porsche 914s, as well as Type 1 engines that have already been upgraded with a spin-on oil filter pump or a remote filter mount. By simplifying the cooling loop, you reduce the risk of leaks associated with complex plumbing while gaining the peace of mind that comes with a dedicated external heat exchanger. It''s an essential component for any high-performance build where engine longevity and thermal management are the top priorities.
