The parts invoice only has SIAC254. I guess thats the part number??

Anyway, good luck. All I was saying is that you can save a few bucks just by searching the internet for info.
Thats where I got mine. Its the updated model and comes with a brand new O ring. Not sure why the dealer charges 3 times as much.

what are the symptoms that you get when you need to replace the IAC? Cause I might have to change mine. the revs goes high to low when I'm waiting for a red light and sometime the car shuts off.

i have 80k miles on my evo and mine went at 60k miles. The car would not idel when it was cold and could not idel with the ac on. Changed This part and it fixed everything

ps i thought it was called an IAC (intake air controller) not a ISC

I think people use both terms
iac- idle air controller
isc - idle speed controller

guys i think i may need one, i tried a smoke/pressure test on the intake manifold last night and no leaks? so this must be the cause of my erratic idle. i'll get some prices from UK dealers.

My symptoms;

1.start the car up idles high 1.5rpm
2. then when warm idles between 2.0~2.5rpm as per video link below
3. i stop at the traffic lights and it will either rev at 2.5rpm or stall
