    Quality Work, Quality look.

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

    Quality Caps

    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++

    Excellent Quality And Looks

    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.

    Engine Bay Caps JDM Blobeye STi

    Absolutely amazing product!!! I brought a complete set in Pink. They all fit perfectly with a tight fit. They are expensive but the the quality is outstanding and well worth it in my opinion. I have only just fitted then, so how they hold up over time is still yet to be seen but I'm sure there will be no issues.

    They are great. Thank you Billetworkz for great products and service.
