    Review & Install Video

    Hello and welcome back to Stage 3 of AmericanMuscle’s project Foxbody, as you can see we’re currently out enjoying the fruits of our labor which took place in the first two stages, and for the first time since we started this project, I can honestly say

    More Power. Increase the airflow in to your Mustangs 5.0L engine for an improvement in throttle response and more horsepower you can feel with a SR Performance 70mm Throttle Body.

    Precision Crafted. This SR Performance Throttle Body is made from a permanent mold casting of 356 aluminum to produce a higher quality casting than conventional sand molds, which reduces porosity for an improved finish.

    Application. The SR Performance 70mm Throttle Body is a direct bolt-in replacement for all 1986 to 1993 5.0 Mustangs. A 70MM Throttle Body is a great upgrade for a stock or mildly modified 5.0 Mustang. Reuses the factory Throttle Position Sensor (TPS).

    Technical Note. The 1986 to 1993 5.0 Mustangs must run both a throttle body and EGR Plate, with all stock connections functional, to maintain street legal.

        I have a 88 LX (5.0) and was wondering if this part was CARB legal?

        • The SR Performance 70mm Throttle Body does not carry a CARB EO # so it would not be CARB legal.

            Throttle Body

            Purchased this back in the early 2016 when I had the foxbody and it fit perfectly. Gave a little more HP and had no issues bolting up. Took no time at all to install either. Loved it.

            Better throttle response, looks good under hood. 4 stars because fitment wasn't 100. Had to use a blow torch to warm up the hose that goes from throttle body to intake to make sure it fit.

            Can't believe I was able to get this for so cheap! Thank you American muscle for the unbelievable discount! Matched up with a 76mm mass air flow housing and my trick flow intake and manifold is bringing in air like never before, way better response and power!

            Things I wish I would have known...

            First, I love it! Big gain in power. 1) I wish the information on setting the idle were a little more complete... 2) I wish the site would have recommended I buy a new set of studs with the throttle body. In fact, all new hardware would have been great! You cannot buy the studs locally, not even at Ford (service part only). 3) I wish I would have known how bad the old EGR spacer was going to stick. It took a lot of penetrating oil (Kroil) and a lot of elbow grease to get the EGR spacer to break from from the plenum (without breaking the studs. 4) I wish I would have known how difficult the black grommet fitting for one of the accelerator cables was going to be. It's just a little plastic stud, so I had to be super careful not to break it while exerting a lot of pressure to get it to fit into the grommet. I noticed that the grommet on the old throttle body faced the other direction too. I ended up using the old one to make it work. 5) I got 2 throttle body gaskets ( 2 more came with the EGR spacer for a total of 4) but no IAC (Idle Air Control Valve) gasket. The IAC was supposed to be in the box. Someone picked and packed and didn't double check. You cannot buy one anywhere, so I had to make one from a gasket kit. 6) I wish I would have known I would have to cut half an inch of my cold air intake aluminum tube to make it fit. 7) I wish I would have known that the rubber coupling that connects the throttle body to the cold air intake would be way too small. I did find one I could use at AutoZone. Like the studs, would have been a great recommendation..

            Installed on a stock 5.0 that was lacking the throttle response that I like from carberation. This product installed very easily, Follow the instructions to set the TPS and IAC and it works very well. The throttle response is great and what I was looking for. It even changed the sound to a little deeper tone. Only one issue and that is a sqeek in the linkage hope to get that found and eliminated.

            Great throttle response.

            As others have mentioned, getting the old egr spacer off was the hardest part of the job. I have the stock plenum and MAF so i'm not getting full benefit possible, but the car is noticeably more quick to respond to the gas pedal. Nice looking expanse of polished aluminum in the engine bay as well.

            Excellent price, decent quality

            Here's the deal, a throttle body is a throttle body. Some have a little better construction than others but as long as it works a SR throttle body is doing the same thing as an Accufab. Buying a cheaper quality throttle body the main thing I am concerned with is vacuum leaks at the throttle shaft bearing as I have seen this problem in the past. This being said I took a chance with SR and mine came fully functional lol.

            Great Throttle body

            took me about 1hr 20min to install, i use the stock intake manifold so i had to do some honing to make it all even for the air flow, but that was easy. After install i test drove it and you could tell right away the difference, throttle response was wayy better and a definite gain in HP probably 10-15.
