Bundle and SAVE! Choose your color combo to dress up your engine bay!

The Precision Raceworks Billet Engine Cap Set is a functional and stunningly stylish way to add a nice touch to any engine bay!

These caps come in three color options so there is always a color that will work for you! Black with Billet, Black with Blue, and the Stealth series (all black).

Many people don't realize it but the OEM caps have a pressure release valve built into them. Often times aftermarket companies don't know this either or just don't care. But our team cares about proper function just as much as we care about the appearance in every product we design. For pressure relief, our caps incorporate the OEM internals, so you get all the functionality of the original caps, ensuring a safe and reliable system in place.

These caps offer superior style and performance-grade components that replace the factory cap not just cover it up. The durable billet aluminum construction provides long-lasting protection and dependability that will upgrade your engine bay for years to come!

      Damages and issues
      Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.

      Exceptions / non-returnable items
      Certain types of items cannot be returned, Burger Motorsports does not allow returns, custom products (such as special orders or personalized items), and air filters can not be returned. We also do not accept returns for hazardous materials, flammable liquids, or gases. Please get in touch if you have questions or concerns about your specific item.

      Unfortunately, we cannot accept returns on sale items or gift cards.

      The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.

      We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. Certain circumstances will require a restocking fee of up to 25% at the discretion of Palenon Performance.

If the item is being drop shipped from the manufacturer, we cannot guarantee a tracking number within 1 business day. If an item is being drop shipped, we cannot guarantee the 24 hour (1 business day) processing time. A purchase of expedited shipping at checkout means that once item is ready to ship, it will ship using the upgraded shipping method. Some manufacturers require 3-5 days to process orders.

If the cancellation is outside of the time frame the merchant fee will not be charged to you for canceling.
