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

This cap 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 guarantee a reliable fit every time. Durable billet aluminum construction provides long-lasting protection and dependability that will upgrade your engine bay for years to come.

Other companies make covers that install with adhesive over your factory caps and can come off over time. These caps offer superior style and performance-grade components that replace the factory cap not just cover it up. Durable billet aluminum construction provides long-lasting protection and dependability that will upgrade your engine bay for years to come!

  • Weight: 0.391 lbs
  • Material type: Anodized Aluminum
  • O-Ring Material: Viton
  • Retains OEM Pressure Relief: YES

PLEASE NOTE:

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

 

Fitment Note

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

          Fancy enough for a wedding, easy enough for a backyard party
          Color: Gold, Color: Gold
          I picked up this 300 Pack Premium Heavy Duty Gold Plastic Silverware set for a recent gathering, and honestly it worked out better than I expected. When you’re hosting a larger group, the last thing you want to worry about is running out of utensils or washing a mountain of dishes afterward, and this set definitely helped with that. First off, the 300-piece set is really convenient. You get 100 forks, 100 spoons, and 100 knives, which made it easy to plan for about 100 guests without having to buy multiple packs. Everything arrived neatly organized in a clear storage box, which actually made it super easy to keep things tidy until party time. The gold metallic finish is surprisingly nice. It gave the table a more polished, elegant look than standard plastic cutlery. I used them for a semi-formal dinner setup, and they blended in well with the decorations instead of looking cheap or out of place. As for durability, they’re definitely heavier than typical disposable utensils. The forks handled pasta and salads just fine, and the knives worked well for softer foods like chicken and cake. They’re not quite the same as real metal silverware, of course, but for plastic they’re pretty sturdy and didn’t snap or bend easily. I also appreciated that they’re BPA-free and disposable, which made cleanup incredibly simple once everything wrapped up. The only small downside is that if you’re cutting tougher foods like steak, you might notice the knives aren’t quite strong enough for that. But for most party foods, buffets, and desserts, they work perfectly well. Overall, this is a great option for parties, weddings, or large dinners when you want something that looks nicer than basic plastic but still want the convenience of disposable utensils. I’d definitely use them again for future events.

          Amazing value, looks great - quite durable
          Color: Gold
          I recently hosted a large dinner party and decided to go with the 300 Pack Premium Heavy Duty Gold Plastic Silverware. Let me tell you, it was a great choice! First off, the set comes with 100 forks, spoons, and knives, which was perfect for my guest list of 100. I love that it’s all in one package, so I didn’t have to stress about running out of cutlery during the event. The heavy-duty plastic feels surprisingly sturdy, and I didn’t have a single fork bend or break, even with the heartier dishes I served. The gold metallic finish added such an elegant touch to the table setting. My guests complimented how fancy it looked for disposable cutlery! It really elevated the overall vibe of the dinner without the hassle of using real silverware or worrying about cleanup. After the meals, all I had to do was toss everything into the trash, which saved me a ton of time and effort. Another thing I appreciated was the organized storage box. It kept everything neat and clean until I was ready to use it, which is a bonus if you're planning an event. All in all, I highly recommend this set for anyone hosting gatherings. It combines functionality with a stylish appearance, making cleanup a breeze while still impressing your guests.

          Slight odor, more flexible than I expected
          Color: Gold, Color: Gold
          These looked like they were going to be heavy duty, but they were more flexible than I expected (see video clip). They probably still will work well, but if you’re poking your fork into something stiff, expect that the fork might bend some. There was a slight chemical odor when I opened the package, and I’m not a fan of that. As someone with MCS, I have to avoid exposure to fragrances and other harmful chemicals, and it makes me wonder what these are coated with. The gold might be cute for the aesthetic you’re going for with a particular gathering or party, but I find it unnecessary. I would rather go with the real heavy duty ones that are clear plastic from a club warehouse rather than these gold ones. I feel that these are overpriced for the quality, but not a bad price if all you’re going for is the gold aesthetic.

          Nice, high end look, disposable
          Color: Gold, Color: Gold
          I hate to spend a lot of money on something that's just going to be thrown away, so typically buy dollar store disposable silverware for parties and gatherings. But every once in a while, you want something more upscale or high end looking. Enter this pricy but pretty plastic silverware. It is perfect for a wedding, anniversary, shower or other event where you want a nicer look instead of basic. It is sturdy. You won't have to worry about it breaking as someone spears a bite of chicken. It looks great! There's only so much you can do with plastic ware but for what it is, it looks really nice.
