      • Increases Rear Wheel Horsepower and Torque
      • Better Throttle Response
      • NO Computer Re-Tune Required
      • Simple Bolt-On Installation

      More Horsepower And Torque. Replace that restrictive factory intake and throttle body with a BBK Performance Cold Air Intake and Throttle Body Combo Kit from AmericanMuscle for more horsepower and torque. This BBK combo kit will greatly improve your engines incoming airflow path to produce more useable power and to increase throttle response.

      No Tune Required. Unlike other Throttle Body and Cold Air Intake Combos on the market today for the Ford Mustang this BBK Combo Kit does not require a computer re-tune. The engineers at BBK Performance really did their homework to improve your Pony's power using the factory tune.

      78MM Bore. Your GT's stock throttle body is a restrictive 56mm, choking off airflow and keeping your Mustang from giving you everything it has. But the BBK Performance throttle body features a generous, free flowing 78mm single bore design for significantly more air to feed the fire under your hood.

      Reusable Filter. BBK designed their Cold Air Intakes with a reusable high flow cotton air filter. So no there is no need to go out and buy a new filter every few thousand miles. Just clean the filter, re-oil it, save money, and go!

      Easy Bolt-On Installation. This BBK Intake Combo Kit is designed to be a straight forward install with just basic hand tools. No extra modifications or special tools are required for a simple 2 hour installation.

      CARB Certified. Best of all, the BBK Mustang Cold Air Intake in the kit is 50-state smog legal under Carb EO# D-245-14. The BBK 78mm Throttle Body is not CARB Certified.

      Application. This BBK Performance 78mm Throttle Body and Cold Air Intake Combo Kit is specifically designed to fit the 1996 to 2004 GT Mustangs equipped with the SOHC 4.6L V8 engine.

      Please Note. A 78mm throttle body works great on a heavily modified or supercharged GT mustang, because stock or mildly modified GT's do not flow air enough to benefit from the larger Throttle Body.

        Fits great

        Well it definitely fits great but you might want a tune. Tune isn't necessary per se but you do feel the engine struggle top end with all that extra air coming in

        Good for the money

        Good product. Only issue I had was the bolt holes weren't tapped deep enough and had to use washers to be able to tighten down the throttle cable bracket.

        Faulty or needs a tune

        Bought this for my 03 gt and I had to put my stock throttle body back on. Every time I rub the 78mm my car never idles lower the 3000rpm. If you truly don't need a tune then that means my 78mm is faulty

        I have so many bolt ins that it's difficult to any extra power. Hoses where to short and felt like plastic fitting might break.

      Air Intake Velocity So my exhaust is basically wide open with o/r x-pipes, glass packs, no catalytics for now and only thing still stock is the headers. I want to get these two items but have heard that you need to be careful opening up the intake and exhaust too much becasue of velocity of the air coming in and it actually loses power. Is that something to actually worry about here or will I still see improvements? Thanks a lot!

      • I had the same setup with O/R x pipe and borla catback and stock headers with this bbk 78mm tb/plenum and CAI and with a proper tune I saw improvements!!

      How much more horsepower does it make?

      • The BBK CAI and 78mm Throttle Body Combo (96-04 GT) does not need a tune and depending on the other modifications that you have in your Mustang, this combo could gain you between 5-7HP.

      I currently installed this and my throttle body cable does not go in the whole on the throttle body combo any ideas ? has this happened to anyone else and how did they fix it ?

      What about the MAF? Does it need to be recalibrated or a new one added?

      • The MAF does not need to re-calibrated or replaced for installation. Unlike other Throttle Body and Cold Air Intake Combos on the market today for the Ford Mustang this BBK Combo Kit does not require a computer re-tune.

      What lb. injectors is this set up calibrated for?

      • The C&L Racer Cold Air IntakeBBK CAI and 78mm Throttle Body Combo will not include a Mass Airflow Sensor. Displayed is the OEM sensor, which will be reused with this kit.
