The stock throttle body coupler can wear out over time. Off-the-shelf couplers can be too long, and have to be cut to fit. But the Cobb throttle body coupler is correctly sized, right from the start. Tough four-ply silicone is resilient and looks great in handsome gloss black with a white Cobb logo. Lined worm-drive clamps are included.
Fits all 2002-2007 WRX, all 2004+ STI, and 2004-2008 Forester XT.
