Fitment Information: 2002-2014 Subaru WRX 2004-2021 Subaru STI 2005-2009 Subaru Legacy GT 2005-2009 Subaru Outback XT 2004-2013 Subaru Forester XT Features: GrimmSpeed does it again with the Enlarged Bore Intake Manifold to TGV Gaskets. Why do you want the enlarged bore style vs. the small OEM? The OEM gasket hole diameter is much smaller than the TGV itself so you are very limited on matching up the ports of the outlet of the intake manifold going into the inlet of the TGV during porting. With these enlarged port gaskets we are able to match the IM and TGV up perfectly which greatly improves air flow quality at a very important location in your intake track- that is right before it goes into the engine! Pick up a couple pairs of these to match up with your GrimmSpeed Phenolic Spacers. Intake Manifold to Tumbler gasket location Designed with enlarged bores to match the OEM TGV diameter Provides an optimal seal Helps improve the airflow Sold as a pair
