The red wrinkle cap is a nice addition and goes with Perrin radiator and alternator cover.

Fits well and matches all the other reds in my engine bay that aren't from the same company. Can't complain!

Extremely satisfied with these. Adds a nice custom touch to the engine bay, for an extremely custom motor. Very well made.

Fantastic engine bay caps, precision manufactured with a fit and finish that is exceptional. Billetworkz customer satisfaction really sets the bar. I had a minor alteration request and my order was immediately adjusted and modified. The order left a few days later and I received exactly what I had requested. This is the type of service and manufacturing that really stands out. Highly recommend. A++

These really stand out within the engine bay. I bought the full kit with the dipstick and I’m very pleased. The washer fluid cap was a tough fit and the coolant cap was an easy on but very difficult to remove. So I used a heat gun on the rims of reservoirs for a minute then pushed the caps on. It kind of form fitted the caps and they are much easier to service.
