Richard ★★★★★

After wrestling with those brittle factory caps for years, these machined replacements finally give the bay a finished look. The "B" stock set had one tiny scuff but you'd never notice it once they're snapped on, and they fit the manual trans models perfectly.

Miles N. ★★★★★

The faded plastic caps were the one ugly spot left under my hood, and these cleaned it up instantly. The machined aluminum has a nice weight to it and the finish matches my intake piping. Install took five minutes with no trimming needed on my 2016 BRZ.

Adam ★★★★★

Installed these on my 2015 BRZ and they're a perfect direct replacement—no more faded plastic caps. The aluminum finish really cleans up the engine bay.
