Universal Sandwich Adapt er Assembly

The VIBRANT PERFORMANCE Universal Sandwich Adapter Assembly (Part No. 17065) is a precision-engineered oil cooler adapter designed for versatile bolt-on installation across multiple engine configurations. This aluminum sandwich adapter accepts dual thread patterns—18mm x 1.50, 20mm x 1.50, and 22mm x 1.50 metric options, plus 3/4-16 and 13/16-16 inch NPT center threads—making it compatible with a wide range of automotive and powersports platforms. The black anodized finish provides corrosion resistance and a professional appearance, while the 10 AN male inlet and outlet ports deliver efficient high-flow capability for engine thermal management systems.

The multi-threaded design eliminates the need for separate adapters when upgrading or swapping cooling systems. Thread compatibility across metric and imperial standards allows the sandwich adapter to integrate seamlessly into engine bays where original equipment specifications vary. The 10 AN ports (0.625-inch ID) support high-volume coolant circulation without restriction, critical for vehicles running elevated boost pressure or extended duty cycles. Aluminum construction balances strength with thermal conductivity, while the anodized coating resists oxidation in harsh underhood environments and extends component lifespan across seasonal storage and high-temperature operation.

This sandwich adapter serves platform-agnostic builders, engine swap enthusiasts, and performance shops standardizing on 10 AN hose systems. Whether configuring a custom cooling circuit on a vintage engine transplant, integrating a modern oil cooler into a classic platform, or upgrading an existing system to higher-flow AN-spec plumbing, the multi-port design accommodates rapid prototyping without sourcing multiple one-off adapters. Compact overall dimensions (5.85 x 4.45 x 7.45 inches) ensure fitment in constrained engine bay spaces common on street rods, race cars, and motorsports applications. At 1.82 lbs, the aluminum construction minimizes parasitic weight while delivering the rigidity required for vibration-prone environments.
