Review on 💨 Efficient Idle Control with Standard Motor Products AC524 Idle Air Control Valve by John Walker

Used on my 2002 wrx. I cleaned up an old IACV and that only helped for a while. This new block came with a new gasket (this is a dealer/online not part of a parts store) and new bolts! These pads stretch A LOT to the point where they can't be trusted to be reused. This IACV appears to have a thicker mating surface, resulting in a more secure, leak-free fit. Drain the remaining (capacitive?) 12V several times. You should see your odometer disappear. The computer goes through the learning process again with the new IACV. Adjusting the small set screw and throttle stop nut improved my idle slightly. My Wrx is heavily modified and has always had problems idling, even dying and having fun often. from driving. I couldn't be happier with this IACV.
