SBC Remote Oil Cooler Sandwich Adapter

The SBC Remote Oil Cooler Sandwich Adapter by ALLSTAR PERFORMANCE is a precision-engineered thermal management solution designed for small-block Chevrolet engines requiring remote oil cooling capability. Built for serious enthusiasts and performance builders who demand reliable heat dissipation in high-output or unconventional engine bay configurations, this adapter bridges the gap between traditional oil passages and external cooler systems. Whether you're running a competition-grade engine or managing thermal stress in a compact installation, this sandwich adapter provides the mechanical interface necessary to relocate oil cooling away from the engine block.

This adapter functions as a sandwich-style port block, installing directly into the engine's oil passage system to direct flow toward a remote cooler unit without requiring internal engine modifications. The compact 4.5 x 4.35 x 5.85-inch footprint allows installation in tight engine compartments while maintaining full structural integrity under sustained pressure cycles. At 1.86 pounds, the adapter delivers minimal weight addition while its engineered passages ensure consistent flow rates and pressure stability, critical factors in preventing cavitation or inadequate cooling during extended operation or high-RPM use.

Performance builders, drag racers, and engine builders running small-block Chevy platforms benefit most from this remote cooling solution, particularly in applications where traditional radiator-mounted coolers prove insufficient or incompatible with custom frame designs. Installation requires standard hose connections to your chosen external oil cooler and integration into the existing oil filtration line—no drilling or welding necessary on the engine itself. Verify your specific SBC variant and cooling system configuration before ordering to ensure proper port alignment and hose routing compatibility with your build.
