Oil Cooler Port Block Off Plate Billet

The Oil Cooler Port Block Off Plate Billet from Racing Power is an essential component for engine builders and performance enthusiasts who are eliminating or bypassing factory oil cooling systems. This precision-engineered block off plate seals the oil cooler ports on your engine block, preventing unwanted fluid leakage and maintaining system integrity during high-performance applications.

Manufactured from solid billet aluminum, the Racing Power R5134 block off plate delivers superior durability and thermal stability compared to cast or stamped alternatives. The compact design (4 x 0.65 x 6 inches) allows for straightforward installation in tight engine bay spaces, while the precision-machined surface ensures a leak-free interface with standard oil cooler ports.

This block off plate is most beneficial for engine swap projects, race car builds, and custom cooling systems. Its minimal weight of 0.12 lbs contributes negligibly to overall engine assembly mass, making it ideal for weight-conscious builds. The billet construction means no porosity issues, consistent material quality, and the ability to handle elevated pressures without warping or failure.
