    Natalie R. ★★★★★

    Swapped out the faded plastic caps on my 2011 WRX and the difference is night or day. The machined aluminum feels solid and the fit is spot on, no wobble at all. Honestly the cleanest five-minute upgrade I've done to this car.

    Julian ★★★★★

    The billet aluminum really pops against the plastic covers, way better than the dull stock caps I had. Install took maybe five minutes with a socket, and they sit flush with no wobble. Engine bay finally looks like someone cares.
