SB Oil Filter Adapter

The SB Oil Filter Adapter is a sandwich-style oil cooler adapter purpose-built for Chevy V8 engine builds where thermal management and system integration matter. This bolt-on adapter sits between your engine block and oil filter mount, allowing you to plumb a remote oil cooler into your circulation loop without sacrificing factory filter placement or engine bay real estate. Whether you're upgrading a street machine for better oil temps under load or building a track-focused V8, this adapter provides a clean, OEM-compatible solution for modern cooling systems on classic or modified platforms.

Constructed from aluminum with black anodized finish, the SB Oil Filter Adapter features dual 1/2-inch NPT female ports—one inlet and one outlet—that accept standard hose barbs, quick-disconnects, or threaded fittings for flexible plumbing layouts. The sandwich design means it mounts directly to your Chevy V8 block pad, keeping the footprint compact while distributing oil flow evenly through both the remote cooler circuit and your standard oil filter. Black anodizing protects the aluminum from corrosion and heat cycling, ensuring reliable service life even in aggressive driving conditions or high-ambient environments. The compact 4.3 x 4.3 x 5.6-inch profile and 1.9-pound weight integrate cleanly without adding clutter to your engine compartment.

Mechanics and engine builders favor this adapter for LS and small-block Chevy V8 conversions, restorations, and performance builds where engine oil temperature control directly impacts reliability and longevity. Installation is straightforward—simply sandwich it between your engine block and stock filter head, thread in your cooler hoses, and integrate your remote oil cooler into the loop. The 1/2-inch NPT ports accommodate most aftermarket cooling systems and hose configurations, making this adapter a versatile centerpiece for any mid-range or high-output V8 thermal management strategy.
