Precision Raceworks oil fill cap bundle, BMW B58 / S58

Precision Raceworks Billet Engine Cap Set is a functional and stunningly stylish way to add that billet vibe in your engine bay.

These caps come in three color options so there is always a color that will work for you, we normally stock the traditional “Precision Blue”, while silver and black are also available as special order (just mention in the shopping cart notes and we’ll take care of it!).

• Heavy-duty billet build, feel the quality.
• Professional looks
• OEM fitment
• OEM function!

Many people don’t realize it but the OEM caps also have a pressure release valve built into them. Often times aftermarket companies don’t know this, or maybe they just don’t care. But we do, proper function is important to preserve. 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.

Original pressure relief valves will be moved from the original caps to these, instructions included.
