    Gain Up to 12HP. Replace your Mustang's restrictive factory throttle body to gain up to 12 horsepower and improve throttle response for power you can really feel. The BBK twin 62mm throttle body will improve airflow where it matters most, maximizing horsepower from all your mods and really waking your Pony up off the line.

    62mm Twin Blade Design. Your stock throttle body chokes off airflow and keeps your Mustang from breathing freely and giving you all its got. This BBK throttle body features a generous, free flowing 62mm twin bore design.

    CNC Machined Aluminum. BBK's throttle bodies are cast from high quality, lightweight 356 aluminum alloy that is finished using CNC machining to ensure a precision fit. They feature double-sealed bearings, o-ringed throttle shafts, and precision die-stamped linkages to ensure a long life and maximum performance for your Pony.

    Bolt-On Installation. The BBK Throttle Body is designed for a straightforward installation and includes all necessary hardware. It is designed to be installed reusing the factory throttle body gasket making it a no-hassle mod.

    50 State Legal. This free-flowing 62mm bore version of BBK's popular twin throttle body is CARB approved for all 1996 to 2001 Mustang Cobras. That means you can upgrade your street-driven Pony without worrying about yearly inspections, even in states that have adopted California emissions restrictions.

    Application. This BBK Throttle Body is designed to fit the 1996-2001 SVT Cobra, 2001 Bullitt, and 2003-2004 Mach 1.

    Technical Notes. This BBK throttle body is CARB certified (CARB EO Number: D-245-13 (1996-2001 only)) and 50 state legal.

    Will this throttle body add on require a tune for a 96 Cobra, when added the K N cold air intake?

    • While not required we would recommend getting a tune for this combination.

    Will this product be smog legal on 2003 mach 1. The website states carb legal for 99-01. Just want clarification.

    • The BBK Twin 62mm Throttle Body will not be smog legal for the 02-04 models no.

    Will this product fit my factory air intake on my 96 cobra?

    • Certainly - this is a direct replacement for the stock throttle body and would bolt up without issue to your stock air intake.

    Will this product interfere with the cruise control on my 2001 Bullitt? I saw in the reviews of the Twin 65mm from BBK that Bullitt owners experienced idle issues when installed. That steered me away from that product, but I still want to upgrade my TB. I was hoping this was the proper alternative.

    • I had a similar issue with my Mach, but it started idling normally after a week of use, I believe you just need to be careful if you install it yourself and you should be fine.

      Sticking issues bbk 62mm TB

      It seems like some of these TB have a sticking issue. There's not much you can do to fix it. And AM wants you to go to a shop and get a letterhead saying that it's defective to be able to get a return. I find this to be absurd. After I paid somebody to install it now I got to pay more money to deal with this problem.

      BBK twin 62mm throttle body

      Good throttle response dont see much of an improvement in hp or top speed but one nit pick I do have is the throttle is sticky and its hard to accelerate without looking like a dummy and revving the engine high but looks pretty cool. Finish is a bit off I am thinking of swapping out the old throttle spring to make the throttle not so sticky. Tried to spray wd40 to make it less hard to open but no change. Maybe it needs to be broken in

      Great product and a Simple Mod

      This is a Great product from BBK and a Simple first modification to your Mustang. It is a noticeable increase over the factory Throttle Body diameters - from a Twin 57mm to a Twin 62mm. The Install was easy and the Fit was almost Perfect. The upper, left mounting bolt was hitting a mounting tab for Mach 1 Shaker Hood Scoop. It was easily fixed and posed no problems.

      Nice upgrade

      This is a nice upgrade from the stock throttle body. Not a huge difference but you can tell more air is getting into the engine. Easy install also

      First, I bought this part from a competitor due to it being sold out here. But I want to spread the word so this horrendous incident of time and money happens to nobody else. I have a 2001 Cobra that just had the engine rebuilt, JBA headers, Magnaflow full exhaust, BAMA tuned, Steeda under-drive pully and a JLT true cold air intake and more done but not relevant to keep going on. I installed this TB and my RPMs shoot up when I pull in the clutch, pedal feels ugly, and idles anyhow it feels which gets worse as the car engine warms up. I followed the BBK online '.pdf' instructions carefully and still runs horrible. I call BAMA and they say a new tune will not resolve the issue and it would be pointless. I take it to a mechanic and he said that it need to have it brought to a DYNO to compensate for the new airflow after messing with it for half a day at my expense because they could not get it to function properly either. But if that is the case then why can't BAMA write a tune to fix it. I think that this issue stumped him too and he told me that to wash his hands of this issue because nothing is wrong with the installation of the TB. I then send BBK an email and get a response back "We have sold that part for 12 years without issue" basically blaming me for the issue and to send it back to get a new one. Nothing mechanically is wrong with the TB and returning it would be a waste of time because they do not know what else to do and have no other recourse to tell me. I am putting the factory TB back on because this issue has costed me and others over 100 hours of trying to figure it out over the course of buying this part. On a last note, upon observation nothing is stopping the screws on the butterflies to come loose and be sucked into the engine. The OEM has the screws crushed on the back to avoid this but the BBK one does not. I am sure that has happened to others and turned a few engines into scrap metal since this part has been sold. This is my true and horrible story. This part is NOT a direct replacement. Do not believe it.

      sounds great with my cold air intake

      when i first installed it i was already frustrated with buying sensors trying to solve an idle problem by most afordable proccess of elimination, well it didn't work and when i first installed it i made the adjustment the instructions called for and the problem was worse than the stock TB i was replacing but soon figured out it was my cruise control cable that needed adjustment which i did not see anything about in the instructions . ran good for about a week and now it rides very rough on acceleration and the gas peddle is very sticky making it hard to accel or decel smooth. car wont give me a break 74k

      Decent throttle body

      Had a little trouble keeping the throttle in place so the RPMs would stay at like 2000 every once in a while but now it seems like its working just fine. Try it out for your self!

      BBK 62mm Throttle Body

      This throttle body is pretty awesome once installed. Had a bit of a problem with the throttle positioning sensor because the screw didn't come out so I went to auto zone and bought another TPS for $28, but no big deal. After it was installed took it for a test drive and definitely felt the low end on it. Not too much of a gain, but definitely noticeable.
