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.

Red Wrinkle

Great quality and heavy caps! The red wrinkle has a texture to it that adds to the look.

Great quality product. Thick piece of metal and easy installation. Paired with the dipstick. You get what you pay for.
