PN - KTD-IAC-ROT

Applications: K20A/A2/A3 & Z1 Throttle bodies

K-Tuned has now developed a very useful part to relocate the Idle Air Control Valve (IACV) on the K-series engine.  If you have ever looked closely at the location of the IACV motor assembly you may have noticed that it is mounted in a very awkward location for engine swaps.  On some K-series engines it actually sticks out in front of the intake manifold and gets in the way of the radiator and / or rad hoses.

The IACV plays a critical role in idle quality and stability.  Many K-swaps will suffer from high idle or surging issues when they are first started.  Most of the time the part to blame is the IACV.  Excess carbon build-up in the valve can cause sticking.  This is why we have also taken the time to create detailed instructions on how to clean your IACV.

You may have seen IACV block off plates on the market.  These are not the best solution to IACV problems because after installation the idle rpm is too low.  Idling at 350 - 450 rpm with a simple block off plate is out of oem spec and causes frequent stalling.  The fix for this is to manually open up the throttle plate to raise the idle.  This done by adjusting the factory set throttle stop.  This is why we always recommend cleaning and keeping the IACV in place as Honda intended.  There are some exceptions such as race engines where idle performance is not a big concern.
