      Lucy ★★★★★

      Installed these on my 2022 WRX and the anodized red really pops against the black plastic. The threaded inserts on the oil cap were machined perfectly, so it screwed on smooth without any cross-threading. Definitely gives the bay a cleaner, more finished look.

      James ★★★★★

      Swapped out the faded plastic caps on my '19 WRX and the billet aluminum ones fit like they were machined for it. The finish has that nice brushed look that catches light without being obnoxious. Engine bay finally looks like someone cares.

      Riley ★★★★★

      These billet caps completely changed the look of my engine bay. The machining on the oil cap is super clean and it threaded on in seconds. Fitment was spot on for my 2018 WRX too.
