With miles racking up in your 6.6L GMC or Chevrolet Duramax, it may be time to reseal the head gasket of your engine. The Cometic MLX Head Gasket is exactly what you need. The MLX line of gaskets are great for stock or performance builds and uses multiple layers of corrosion resistant stainless steel for increased strength. The outer layers of the gasket are embossed and coated with a flouroelastomer rubber based material that is heat resistant to 482 degrees. This material is designed to meet the demands of harsh sealing environments, load conditions and surface finishes. The center layer or shim layer is a stainless steel layer that is folded back upon itself to create the locking portion of the bore seal. Cometic Head Gaskets are designed for a strong seal you can trust in your diesel engine. Right side only.

Great case
Color: 03-dark Grey, Size: 20" X 26" (Pack of 2)
Love these pillow cases! FYI: 20" X 26" are PERFECT for supposed "queen size" feather pillows. 20" x 30" ones are too big and allow the feather pillow to flatten out too much. There is a bit of stretch to the cases. The "cool side" of the pillow case IS NOTICEABLY COOLER than the other side. Good zipper.

Hmmmm not really a cooling case
Color: 07-beige, Size: 20" X 36" (Pack of 2)
I bought these because like many I get hot at night, right around my neck. While it's soft and satin to the touch, and cool to touch, it doors keep me cool presay. I still get hot, I flip the pillow and because it's cool, I get cooled down. Again doesn't actually keep me cool all night though.

That I keep my head, cool
Color: 01-grey, Size: 20" X 26" (Pack of 2)
They are cool and that’s exactly what I wanted. Something that wasn’t hot and I’m very happy with my purchase.

Finally sleeping through the night without waking up drenched
I was dealing with night sweats almost every night. Waking up overheated, flipping my pillow over constantly, just uncomfortable and restless. It was starting to mess with my sleep in a real way. Since switching to this cooling pillowcase (and pairing it with a cooling blanket), it’s been a completely different experience. I’m actually staying cool through the night and not waking up soaked or irritated. The fabric feels cool to the touch right away and doesn’t trap heat like a regular pillowcase. It’s smooth, comfortable, and still feels good after washing. Not stiff or weird like some “cooling” materials can be. Is it magic? No. But does it noticeably reduce overheating and help you sleep better? Absolutely. If you run hot at night or deal with night sweats, this is one of those small upgrades that makes a big difference. I wish I had bought it sooner.

so far so good
I was surprised at this pair of pillow cases only because the material seemed impossible to be cooling - it's that weird polyester blend. So far I have not awoken feeling sweaty around my face and scalp. I don't recall what I originally paid but I think it is great value for money! If you are sensitive to out of the box smell, I washed mine first and it didn't impede on the efficacy of the cooling!
