It’s no secret that GrimmSpeed intakes feature performance and aesthetics that lead the pack.  With years of design theories and knowledge gained from our successful intake program, we have developed solutions that increase power and are very easy to install and tune.  The only thing we were missing was an intake system for early models, and after nearly two years of development and testing we are extremely proud to offer what we feel is the best intake for your 2002-2007 Subaru WRX and STI, and 2004-2008 Subaru Forester XT.
