Works like they should
I added these to my 2010 forester while the engine was apart. Figured may as well squeeze all the power out of it as I can. Worked perfect

Fitment Information:
1999-2001 Subaru Impreza
2000-2004 Subaru Legacy
Features:
In case you weren't aware, the cooler your intake air is the more HP your car will achieve. One way to reduce intake air temperatures is to raise the intake manifold off the engine with GrimmSpeed's Phenolic Intake-Manifold-to-Engine Thermal Spacers. Phenolic spacers have been used for years by many other specialized automotive companies, but GrimmSpeed is one of the first to offer this technology to the Subaru world.
It is recommended to use one OEM intake manifold gasket on each side of these GrimmSpeed spacers to allow for proper sealing. Gaskets are available to purchase separately.
