Love These Caps without Branding!

I bought these because they look good with artistic logo for each fluid type, and don't have "Billetworkz" all over each cap as an advertisement. Much appreciated!

Looks fantastic for reliving my 90s JDM street cars growing up. Red Powdercoat finish.

Nice touch to the bay

Caps add a nice accent to the engine bay. Really love the way they look

Awesome accessories!

I just purchased the set of 5 caps in wrinkle red for my '19 WRX STI and they were very impressive. The material and the finish were outstanding, also very sturdy. I should have purchased the kit a long time ago. I'm very pleased with the product and the look.

The added color makes the engine compartment pop!

These caps look great, and the bright red (non wrinkle in my case) works really well against the rest of the engine compartment and the orange of my WRX. Don't mind that I added the Perrin oil filter cover (Billetworkz doesn't have one).

The only minor thing I would change - and it's small - is that the marking on the oil fill cap doesn't orient square to the markings on the other caps, which you can turn any way you want. It's because it's a threaded cap. My guess is it could be fixtured to square up better when it's marked. But it still looks great, I'm just a little OCD.
