Performance is proud to offer 8mm phenolic grade CE spacers for your Subaru 2.0L and 2.5L engine. This is a simple, cost effective way to maximize the power of your current set-up. The 8mm spacer offers superior thermal insulation and also aids in raising the intake manifold*. This can be useful when plumbing custom intercooler piping or rotating the intake manifold. 

Why it works: The concept behind the phenolic spacer is simple: isolate the heat produced by engine from the entire intake tract. This results in a cooler path for the intake air. This leads to lower and more stable intake air temperatures (IATs). Lower IATs mean you have the capability to make more power with your current set-up. 

*Due to clearance issues that can arise with raising the intake manifold, please confirm fitment for your specific application before ordering.
