We’re big believers in the little details. The SPE Motorsport Billet Radiator Cap is a simple swap that replaces the factory plastic cap with a durable 6061 billet piece, finished in black anodize for corrosion resistance and a clean look.

It installs in seconds as a direct replacement, and it’s designed to match the rest of our billet lineup so your engine bay looks as clean as it performs.
