The black OEM coolant reservoir cap doesn't do the PSP Diesel Aluminum bottle justice, so why not dress it up with our Billet Aluminum Radiator cap cover. With a laser engraved graphic, this cap cover will make any build look good! You can also choose to include a new OEM cap with your order or just use your existing cap.
Note: This is a cover for the OEM cap, but it grooved to allow a near permanent install over your OEM cap. It will firmly press on over the cap and allow you to install and remove the cap without removing the cover.
