Phenolic Thermal Intake Manifold Spacers

Remember when your buddy came over to show you his new Subaru STI that he just got. He pops the hood and you lean in and rest your hands on the intake manifold and hit some high notes that you've never heard before because you burned your hands? Well, one of the benefits of Phenolic/Thermal Intake Manifold Spacers is that they absorb the heat between your heads and your intake manifold.

Now, even though Phenolic/Thermal Intake Manifold Spacers sounds like an off-the-shelf product for the Starship Enterprise, these are actually quite an overlooked modification you can perform to your vehicle. When you lower your intake temperatures, then you are improving performance, this means more horses in the stable of your engine, and more torque monsters pushing you. 

RallySport Direct carries a great selection of Phenolic/Thermal Intake Manifold Spacers from the likes of Grimmspeed, Cosworth, Crawford, and aFe. Not only do we carry them for several Subaru Models, those who drive a Mitsubishi Evolution, a GTR, a 350Z, BMW 135/335, and even for the Hyundai Genesis. 

And if you're more interested in creating more flow in the intake, check out our great selection of Tumbler Delete Valves, and let your engine breath a little better by upgrading to a cold air intake
