GrimmSpeed Intake Manifold Phenolic Thermal Spacers / Gaskets Description

Keep your intake manifold cool, make more power!

It's well know in the performance community that excess heat doesn't promote performance. Cooler air is more dense and as a result can contain more combustible energy by volume. A great way to reduce intake air temperatures is by better insulating your intake manifold from the hot engine cylinder heads. Stock thin metal or composite gaskets allow a large amount of heat to transfer from the engine to the intake manifolds of a vehicle. The then hot intake manifolds allow much more heat to transfer to the incoming air, reducing power and response. Every 5 degree reduction of temperature improves power potential by an additional 1 percent! By increasing the thickness of the gasket and constructing it out of special Phenolic heat resistant materials Intake manifold temperatures can be greatly reduced to promote cooler intake air and better performance.

GrimmSpeed is well aware of this information which is why they have designed these GrimmSpeed Phenolic Thermal Spacers to help bring air intake temperatures down and improve power! With the installation of the GrimmSpeed Phenolic Thermal Spacer you will be able to feel a distinct difference right away. Intake manifolds that are normally to hot to touch are cool enough to lay your hand directly on them when using the Phenolic Gaskets. The Phenolic Spacers conduct about 3 to 9 hundred times less heat than an OEM steel gasket! They are also tested to withstand up to 5 hundred degree temperatures (far less than the operating temp of all production car engines) and are compatible with race fuel, E85 and methanol. In tests performed under consistent outside temperatures the 8mm spacers showed decreases in temperature of over 44 Degrees Fahrenheit!

Key Features:
  • Greatly reduces intake manifold heat soak.
  • One of a kind Phenolic material (not cheap cutting board like some other brands).
  • Direct bolt-on installation.
  • Made in the USA!
Installation Note: Although the Grimmspeed Phenolic Thermal Spacers can be used without additional gaskets, we recommend still using a high quality composite gasket (or OEM gasket) on each side for the best seal.

I couldn't be happier with my purchase! I ordered around 9pm, and it was delivered to my door befit 11am the next day! I didn't pay for expedited shipping, but it was shipped faster than big shipping companies have a hard time doing! The price was even better than I could find on the internet at rival retailers. So, with the cost of the intake, shipping, and communication from the company, I'll be back back for more and I highly recommend this retailers! Thank you!

First time buyer from PIT. Working on a new project car. Customer service was solid! After placing my order they even contacted me to make sure the parts I ordered were compatible with my specific vehicle. We exchanged some info and verified the parts would fit my ride. Delivery was communicated, tracked, and arrived on time as expected. Got exactly what I thought I was gonna get: exact part and the replacement went smooth. Have PIT bookmarked now and will use them again soon! Prish PIT!!
