      Good stock iac valve replacement

      I was looking for a good replacement for my stock i.a.c valve and i decided to purchase one from American Muscle. It was easy to install and it got rid of the surging idle issues. I would expect it to come with a gasket but they’re only a couple bucks at a parts store.

      It is well worth the price.

      I had trouble for years with using store brand IACs for my Mustang. I always thought that there was something else causing the issues and just dealt with the hanging idle. After putting a new motor in I finally caved and bought the Motorcraft one and it has worked perfect ever since. I've definitely learned with Ford that its always better to spend a little more and get the Ford brand parts.

      Almost perfect

      This Motorcraft part worked right out of the box, unlike other 3rd-party components I had tried. Would have given it 5 stars if it included the gasket like others do.

      Perfect

      Had idle problems with my 04 mustang gt, bought this online and the idle problem was solved, and also took less time arriving to me so that's good.

      Perfect fit

      Great replacement part for a commonly failed item. Factory fit, no problems! Replaced while upgrading to the BBK 73mm throttle.

      Mixed Feelings..

      I installed this part right away and noticed that my car actually has the symptoms of a bad IAC that everyone mentions that I thought I had. It wasn’t until I installed this part that I realized the cars original IAC is in better condition 125,000 miles later compared to this “new” IAC as it actually runs rough and the check engine light is on. Checked the light and it turns out it’s the IAC. Rather disappointed about the outcome of this car part.

      This part was a perfect fit and has provided better overall performance. My car now idles at a constant rate and the engine does not stall anymore..

      Fixed the known surging

      Fixed the surging and gurgling sound the engine would make when cold or hot, works like a charm. Does not come with a gasket! But O'Reillys had them for less than $2. Installed the part in the O'Reillys parking lot in 5 minutes!

      Problem Solved!

      This part was a perfect fit on my 03 GT. Had hanging idle issues. Tried an aftermarket brand from my local autoparts store. That part had a spring inside of it. Don't try and save yourself money and by the cheaper aftermarket brand. Spend the extra money and save yourself from having more problems down the road. This part is OE and corrects the hanging idle issue and does not have a spring inside. Either use your IAC gasket or buy a replacement. This part does not come with a gasket.

      Idle Air Control

      I had the up and down idle on my 04 Mustang so I ordered this and it did the trick. Delivery was very fast and the part was very easy to install. It took 15 minutes to install. It was the answer to my problem. It did not come with a new gasket so make sure you pick one up before putting it on.

      IAC

      do not buy an aftermarket iac, tried 2 of them and they had my car with a hanging idle around 21/2 to 3 rpms constantly. Bought a ford original motorcraft iac, put it on and problem solved. I highly recommend the ford iac from American muscle.
