The Precision Raceworks Billet Coolant 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 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.

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.

        Very comfortable. On the soft side.
        Size: Queen / Standard, Color: White
        Soft, but not too soft. I would actually give 4.5 stars. The pillow is a bit too long and bulky, wish it had a bit more support, but overall, great purchase considering the price. Hopefully it doesn't degrade after washing.

        Excellent pillows that are worth the cost
        Size: Queen / Standard, Color: White
        These are wonderful. Completely relieved my back pain the first night I slept on them -– I put one underneath my back as I slept, and a weeklong terrible pain vanished overnight. Felt like sleeping on a cloud. As others have noted, they are neither too soft nor too firm…they’re really just right, and I think would make great guest room pillows since everyone would like them. These were definitely worth the money.

        Great , fluffy pillows
        Size: Queen / Standard, Color: White
        They came compressed into a small roll so I was wondering how they would do. BUT they fluffed up to incredible size and comfy feel. I am impressed so far!

        Pillow comfort and quality
        Size: Queen / Standard, Color: White
        Bought this for my husband. He is very happy with it. It is well constructed. He doesn’t like too firm or too soft. It meets those requirements. Very reasonably priced. I have bought very expensive pillows that aren’t even comfortable!

        Pretty good.
        Size: Queen / Standard, Color: White
        Me and my fiancé have been going through a lot of pillows, trying to find the right ones. We go to this local hotel to unwind and use the whirlpool sometimes. Their pillows are immaculate. So I starting looking at “Hotel Pillows”. These are not the same as the hotel pillows, not even close tbh, but they are the best ones I’ve bought so far. They are comfy from day one. I was worried when opening the box and seeing that they had the same cover on them as others I bought before, but they were not the same. Pretty comfortable, and less neck pain than any of the other ones. My house is like the house of pillows and I am finally going to start getting rid of the old ones. Maybe we’ll find some down pillows to put on our registry, but until then, these are staying on my bed.
