This is the original-equipment hood scoop for the 2004-2005 WRX STI. It is a direct bolt-on for any '04-05 WRX. It DOES NOT fit the earlier 2002-2003 WRX hood. Unpainted; have your body shop paint it to match your car. The STI does have additional hardware under that scoop. There is a larger-size hood duct to properly deflect air downward, and there's a rubber "bellows" that goes between the duct and the intercooler. If you don't yet have an STI intercooler, you probably won't need the bellows.
We also sell the metal scoop insert that helps guide air onto the intercooler.
This hood scoop is BIG! You MUST make sure all the studs are firmly attached to the hood -- we also sell the nuts for that. Otherwise it'll tear itself off your hood at speed. (Ask us how we know.)
Fits all 2004-2005 Subaru WRX and WRX STI.
