    cover up the factory eye sore cap

    January 09, 2015

    This is definitely a nice piece. It looks so much better than the factory A/C cap, and this cap matches perfectly with the other Modern Billet Engine Dressup Kits.

    A little detail...

    October 13, 2014

    This cap it's, well....exactly what it is: a cap. It's chromed, and it looks great compared to ugly stock A/C cap. It simply sits on top of old one. You have to use some sort of adhesive to make sure it doesn't fly off on first ride. I chose a sliver of double-sided 3M tape and it's perfect. It took 1 minute to prep the 3M tape and 3 seconds to complete install. Nice little addition.

    Looks nice, needs help with the fit.

    September 08, 2014

    I took the advice of some other reviewers and wrapped the cap with a few wraps of electrical tape and then slid the cap over that and it fit snug. If I hadn't done that I have no doubt that the first speed bump I went over it would have popped right off. It certainly adds some more bling under the hood.

    ac chrome cap

    April 24, 2014

    I like most all American Muscle products and I'm sure they'd like a honest opinion.The fit is loose and no way to tight or hold it down.looks like a make up bottle cap.But cann't really find any other options out there if your like me who takes his or her car to shows and likes it shiney under the hood.Id buy it again just because of that. But not the best item I ever purchased from American Muscle.

    • Response from AmericanMuscle

      This cap isn't designed for a 2011 Mustang, but another customer has installed this cap on his 2011 as well and used some electrical tape around the stock cap to make it more snug. Hope this helps!

    Looks good but...

    April 17, 2014

    Another dressy piece for under the hood. Price could drop a few bucks to make it even better. Only minor issue is that it isn't threaded or fitted to stock cap. Had to use electrical tape around the stock piece for a tight enough fit. Easy fix though.

    Looks Great

    November 28, 2012

    Looks really nice once it is installed. The only minor issue I had was that it didn't come with anything to secure it on the existing AC cap. I added a small piece of 3M doubled sided tape to prevent it from bouncing and rattling around when the car would move. Other than that it is a simple and easy to do and it looks great.

    Chrome A/C Fill Cap Cover

    November 10, 2012

    Adds the finishing touch especially when installed with the chrome underhood dressup kit. All that is needed is a little silicone or 6000 glue to hold it in place.

    Chrome A/C fill cap cover

    July 27, 2012

    I installed this on my 2011 Roush Stage 2. I did wrap the stock plastic cap with a couple of rounds of electrical tape then pushed the cap over that as a nice snug fit. The finish looks great and the chrome cap covers the weld of the A//C fitting which I disliked. Good product and I highly suggest it

    Great look

    June 29, 2012

    Looks a lot better than the stock cap. Add with all the other chrome caps & the engine improves the look of the engine definitely.
