  • Increases Rear Wheel Horsepower and Torque
  • Better Throttle Response

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.

my question is will the 78MM be bad for my car? i noticed in the description it says please note that the 78 MM throttle body is for supercharged or heavily modded stangs.. on my 02 GT with 70k miles only performance mods i have are this same BBK kit as well as bbk underdrive pulleys currently installed, soon i will add more performance parts but for now is it bad on my car having the 78MM?? soon i will look to add a full exhaust system (headers, midpipe, catback) also 4.10 gears w/bama tuner combo kit.. thanks.

  • I installed a 78mm on my 2004 mustang gt several months ago. Any noticeable performance improvement? Yes, noticeably quicker throttle response and much louder huffing sound of air coming in. Any noticeable problems or damage or lowered mpg or power? Nope, none. Would i do it again? If someone up and stole my bbk 78mm plenum would i replace it? Definitely yes! That loud huffing sound when i trounce down on the pedal is priceless.

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!!

    Increase Throttle Response

    It really brought the mustang to life! You can tell instantly that it improves the throttle response and can feel the power difference. Only took me an hour or so to install with minor mechanical skills. Worth the 400$ and you won't regret it!
