Genuine STI Performance Air Filter.
This air filter is manufactured by the world renowned STI department of Subaru.
Brief description from STI:
"This air filter element has a high dust collection performance compared to the standard unit. This is achieved by using a flame retardent, non woven fabric which reduces the air filter resistance which increases air flow which in turn increases performance. We have added a stainless steel mesh protector that is to prevent deformation of the element. We have also improved the sealing around the air filter insert by using double gaskets."
As with ALL of our products, this is a GENUINE STI PRODUCT which we buy direct from Japan.
Fits ALL 2.0lt and 2.5lt Subaru Imprezas 1992-2008.
Also fits Legacy and Forester.
