    Riley E. ★★★★★

    The anodized red finish on these caps perfectly matches my STI's brake calipers. The oil cap threads on smoothly and feels much more substantial than the factory plastic piece.

    Matthew ★★★★★

    Snapped these right onto my 2011 WRX and the difference is night and day compared to the faded plastic ones I had. The anodized red finish is super consistent and really pops under the hood.

    Eli W. ★★★★★

    The billet aluminum finish on these is a huge step up from the crusty factory plastic. Fitment on my 2011 STI was spot on, no wobble or threading issues at all. Engine bay finally looks like it belongs at a car show.
