Standard Motor Products Idle Air Control Valve - AC519

This Valve was less than half of what a Subaru dealer was going to charge me. Even the local auto parts place said the brand and price was good. I installed it in less than fifteen minutes thanks to a YouTube video. Even though I went through the computer reset process initially the valve did not work properly. I did not remove it and continued to drive with it. After a week my car computer adjusted to it and now it works perfectly. My run-away idle problem appears to be solved. I paid $149 for my valve using Prime.

OEM fit and function on my 2004 Subaru Forester. It fixed the idle problems immediately. Now only question is, how long will it last? This one is about $100 cheaper than OEM, yet still at $250 it seems like highway robbery for such a small simple thing. Can't give it 5 stars due to the ridiculous price.PS this did not come with the o-ring. Remove your old IACV carefully and if you're lucky the o-ring will still be intact and you can reuse it.Follow-up: over a year later, still working just fine.

The part I received looked like every other 15$ part on Amazon not the one in the picture

Followed the online video for proper removal of the faulty old unit and then proceed to install new IACV AC519.Connected my laptop and ODB2 to clear the faults after reading for any additional issues then promptly cleared the ECU. Started the Forester for the learning process to begin. Turn on A/C and took a little drive and all is well.Perfect replacement for the old A33 660 R00 UNISIA JECS that came with the car from the factory in Japan.

This idle air control valve failed after two months, and this one is supposedly better quality. Hopefully it’s still under warranty but I need to call the seller as no email is available. I’ll update my rating depending on the seller’s response.Update: Amazon is accepting a return with a restocking fee, since the manufacturer didn’t have a record of this sale (it clearly went through a 3rd party). Kudos to Amazon for standing behind the sale and pro a refund.

Part performed as advertised. I'm tuning the car and the original one froze. This was a good option. I took a gamble on a cheap replacement and it worked since I'm experimenting on the vehicle anyway.

It's was good.

It helps but still diagnosing the idle problem. O2 sensor next.
