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 3x Thick 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 #14035AA421 on each side of these GrimmSpeed spacers. These are available to purchase separately.

I needed to lift the intake for better fitment of other parts and this did the trick.

Fit great and helped with getting my IAG fuel rails to clear the AVCS solenoids. If you have the intake manifold off you might as well do this!

Fitment was spot on. Material was made of very good quality.
I love these spacers only down side to running a 2.5i na manifold on an sti is corn to find out you need to double the spacers to make it clear avcs so had to order two sets.
