The SSS RB oil cooler kit. 😎 A big part of the solution for RB oiling issues. Replacing the stock oil filter block and cooler, this kit is CNC machined and hand-finished/ported for increased oil flow. Common O-rings replace the hard to find gaskets. If you have an Nissan RB, this is the kit for you!
