Twin 65mm TB For 2003 Mach Won Is this a ok upgrade for a mach 1 thats pretty much stock? or is this product more designed for a car with more done to it to get any real gain? I just have a JLT Ram air on my Mach and magnaflow catback and x pipe. and another question, what size TB does my 2003 Mach Won come with stock?? thanks!


Helpful (4)
  • Stock is dual 57mm. If you didn't have the intake and catback, I'd recommend the BBK twin 62mm version of this product. Since you do, this one will work well to get the most from your Mach 1. To really take advantage of the larger bore on this version, get a larger MAF (Ford Perf. 90mm), headers, and a custom tune.

If installed will it pass VA emissions inspection?

  • Hello, depending on your states emissions regulations will be the deciding factor. This BBK product is not legal for use in emission restrictive states like California for example. For states that are not emission restrictive it should be just fine and work great!

Answer This Question

My auto Mach 1 is putting down 437rwhp and about 400rwtq through a Vortech H/O kit with full exhaust and CA intake. I'm wondering if upgrading from the stock 57mm TB to the 65mm TB will make much of a difference or if I should go bigger? Should I be concerned about idle, keeping cruise control and having to do any retuning?


Helpful (0)
  • I definitely think this bigger BBK Twin 65mm Throttle Body will be a good upgrade. As long as you have the tune on your car adjusted after installing this throttle body, you should not run into any issues as far as idling, cruise control, or any type of return system.

    Wasn't expecting that....

    Added on with Mac headers and new Eibach shocks/struts with a retune, all provided by my little lady. Everything on the car felt new but the gas pedal went from night and day with this mod. A little over my budget but awesome results and easy install. 2004 Mach 1 w/86k miles.

    2001 Bullitt install 65mm...

    I like the product overall, but it was pretty difficult install I had to troubleshoot some areas. I had to troubleshoot the cables to connect it to the throttle body such as the cruise control cable it didn't fit properly and it made my throttle go up to about 3000 rpm . the issue have me thinking that it was my IAC, but come to find out it was just my cruise control cable being too tight and not properly fitting. I had to improvise and actually been the metal piece that the cables are connected to and bring the cruise control cable closer to the throttle body so that it would read the engine out beyond 3000 rpm . other than that the product is great! My 2001 Bullitt Martian is running excellent!

    Great Purchase

    It was a bit difficult to install on a 2001 Bullitt but it was well worth it. The only problem i have is the cruise control linkage did not work, it would have kept the throttle open at idle. Great power though, and the throttle response is great. I suggest getting a dyno tune to get the most out of it.

    a definite buy

    This throttle body opened up my 98 Cobra's airflow so much!! With the 90mm Lightning mass air flow and JLT CAI, the difference is just ridiculous. The 4.6 pulls in so much air now!! Noticed the biggest gain at lower rpm, hella more low end torque than before, and in every gear.

    I bought this for my 04 Mach 1 it was pretty easy bolt on if you have the right tools and I can tell a big difference in the throttle response you can hear it suckin the air in which sounds awesome worth every penny

    96 cobra

    Good product but it did have some issues. First the hookup for the cruise control would keep it open so I have to keep it undone. Second my stock tune could not keep up with all the air coming in so if you are going to get it I suggest getting a handheld tuner to go with it. But don't get me wrong I got a good gain from both judging by the seatopants meter. I will be posting a side by side comp here shortly.

    Great Quality Throttle Body

    I installed this throttle body on my 1997 Cobra without a tune. I currently have a K&N FIPK with the stock MAF. As mentioned, you will have to disconnect the cruise control cable, or else it will idle around 3,000 RPM. The car was noticeably louder, but not much. I might have noticed a small increase in power, but it's hard to tell. I can feel that it's sucking in a lot more air, so I'm sure when I tune it, it will really shine. This throttle body is light weight and high quality. I've been happy with every BBK product I've bought to date. I would recommend this product, but wait until you can buy a cold air intake and tuner at the same time.

    Easy Install

    The install only took 30-45 minutes and everything lined up perfectly. I read other reviews where people had to leave their cruise control cable unhooked because it made the throttle stay open. I didn't have that issue. Just FYI for your install, the only issue I had with the install was removing the factory screws from the throttle position sensor. I ended up having to drill the factory screws out to get the TPS off of the factory throttle body. If you don't want to drill them out you can buy another TPS at an auto parts store for around $30. Overall, I am pleased as always with the AM products. As far as performance gains, I did notice a little better throttle response. I have several other bolt-ons and a SCT tune so it was hard for me to tell how much actual horse power I gained. This is a must have and an easy bolt-on DYI project for any Mustang owner.

    65mm Throttle Body

    Love the throttle body, Had a vortec supercharger installed last year notice it lag a bit espeacially on the lower R.P.M.s this year I change the stock 57mm to the BBK 65mm, notice the difference right away. No more lagging, when I punch the peddle the power is instant from low revs all the way to the top. Very impress with the difference, worth the 350 bucks! Install it with a friend the video A.M. provide sure help. Cruise control cannot be hooked up with the new T.B. or else the revs will stay too hi. Not a big deal cause I probally only use it twice since I brought the cobra in 97. Thank for the no hassle delivery, arrive on the date you stated. Would sure recommmend to anyone caught in the same situation as I was.

    Not so great at all. Very overpriced. I never have liked BBK, never will buy parts from them and regret getting this throttle body. Had to adjust the idler screw for my car to stop dying during idle. Gas pedal is very sticky and have a very hard time adjusting, just overall cheap part. Not much performance gain. Don't buy.

    Great throttle response

    Has great throttle response,very easy to install. On the Mach 1,one of your shaker hood mounting bracket mounts to one of the throttle body bolts. BBK did not leave enough room for the bracket to mount properly. So you have to cut your bracket down a tiny bit, aboutan1/8th of an inch and it will fit perfectly. Comes with modding. Not a big deal. But overall great product for the money.

    I can feel an increase in acceleration on my '97 snake throughout but especially at wide open throttle. It was easy to install with everything an exact fit. Only adjustment necessary was lengthening the cruise control cable a few notches, (stock cable is adjustable) and I was on the road again !
