Looks nice, but price could of been a little friendlier.

It's definitely very expensive for such a small little cap that just sits on top of the factory button. It's definitely very nice looking. It's just very expensive for a cap.

Install is a breeze!

Love this simple mod! Install takes 30 seconds - all you have to do is remove the adhesive backing and slap it on over the existing SI control knob. I've had the SI cap on my car for ~1 year and it has stayed put with no issues. Great product to upgrade the look of the interior.

Black SI drive cap w/ STI engraving a very nice touch to interior

Have been getting all of the silver out of my interior and the black SI drive cap with the STI laser engraving looks very crisp while keeping the black theme

Beautiful piece

Just what I was looking for to match the HVAC dials and my shift knob. Turned out great and had the STi icon engraved. No fitment issues at all. Thanks!

Looks great!

Had some initial issues with the fit, but after a very quick email exchange my concerns were addressed and the cover was installed. On a Saturday no less! Thanks for the help Austin
