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!

PLEASE NOTE:

These do require assembly and swapping the pressure relief valves from your old caps to your new billet caps. 

 

Fitment Note

If your primary expansion tank cap looks like this:

You will need to purchase a different coolant expansion tank cap to use as the donor cap.

      Great sunscreen!
      Style: 4 Fl Oz (Pack of 1)
      Eucerin Sunscreen works well and applies cleanly, not greasy. I spend a lot off time outdoors and I am satisfied with the sun protection this product provides.

      Don’t rub, break it down between your fingers and dab!!
      Style: 4 Fl Oz (Pack of 1)
      Great sunscreen. The first time I applied it, i made the mistake of rubbing it in so it gave me a white cast. I learned my mistake the second time, spreading it in between my fingers and than dabbing it on my face, it gives a cast at first but after a few minutes it went away. And it feels so good. like I’m not wearing anything. I tried the tinted sunscreen it feels good but it made me look orange. I used to wear the Eucerin Daily Lotion spf 30 but they discontinued so I had to look for a replacement and after trying other sunscreens they were all terrible; greasy, allergic reactions and too creamy! This one’s perfect, it’s definitely my new go to!!

      The Only SPF My Skin Will Tolerate!
      Style: 4 Fl Oz (Pack of 1)
      After 20 rounds of radiation, I was given a list of exactly four things I could put on my face--things like water and Vaseline. Of course, I was also instructed to wear SPF in "all visible light." However, finding a sunscreen my skin could tolerate proved to be a challenge, as even those made with clean ingredients, marketed for babies, and/ or claiming to be hypoallergenic resulted in hot, angry rashes. Price point also didn't matter; I tried everything from drugstore to premium brands. Thankfully, when this product came on the market, my dermatologist suggested I try it. I've been wearing it ever since. It IS thick so I usually rub any remaining face moisturizer into my palms and then add the Sunscreen, rubbing and warming it between my palms to make it more easily spreadable. Then I press it onto the skin on my face with my palms and fingers--I don't like to pull or tug too much at the skin on my face. At first, there is a visible white cast, but it disappears within a couple of minutes. If I'm really in a hurry, now I can mix a tiny bit of my foundation into the sunscreen so that it spreads faster and I can move on from the white cast faster--I know I lose some sun protection factor that way, but my derm says I also gain some protection in the tinting, so it's okay. The important thing is that I get it on in whatever time I have. I'm just grateful to have found something that doesn't upset my crazy-sensitive skin! Wishing all you sensitive beauties protected fun in the sun...

      Good sun protection without chemicals, without a high price.
      Style: 4 Fl Oz (Pack of 1)
      I've bought this a couple of times. I feel like it gives excellent sun protection at a reasonable price. I mostly use it on my face. When I first apply it, it looks a little white and pasty, but it doesn't take long for that to go away. It's a little greasy at first , but I have dry skin, so I it absorbs in. I like using a sunscreen that doesn't have a lot of chemicals. This works well while using ingredients I feel good about putting on my skin.
