Product Description

WRP Technology is proud to announce it first ever 1 MM oversized valve for the QR25. Made from Stainless Steel several features make our valve superior to the competition. Our valve is lighter in weight vs the competition. Also, most importantly our valve uses the factory retainer and lock. Nissan's retainer and lock for their valve train is among the best in the industry. Using a titanium retainer it is far superior over the aftermarket lock systems out there. In conjunction to this, we have incorporated the super flow style valve which is an undercut stem for super flow design.
