2004 SUBARU IMPREZA WRX STI
RallySport Direct carries a great selection of heads for those of you looking to upgrade during your rebuild process. We carry CNC ported cylinder heads from the likes of Cosworth which for those who don't know, has a rich history in motorsports and Formula One. These cylinder heads are mainly available for the Subaru WRX/STI, and for the Mitsubishi Evolution, although not limited for future acquisitions. Some of these heads will come with the option of camshafts, while the other heads will come bare. Make sure when shopping for heads, that you check out our great selection of short blocks, head gaskets, and valvetrain components.
