With its CNC machined billet aluminum construction and split-shaft design, this top of the line 90mm throttle body kit from Accufab delivers maximum performance and reliability to put you ahead of the pack. Included is a 2" blank solid aluminum spacer with no water passages or tubes, which provides options for mounting your stock cable bracket.

Forced Induction and Built Motors. This track ready throttle body will support your built or forced induction 5.0 engine. Note that a dyno tune will be required after installation of this throttle body due to the amount of sheer amount of air provided to your engine.



Feel the Power. An aggressively sized 90mm race throttle body will deliver the air your heavily modified engine needs to maximize both existing and future modifications. With this kit, you'll bolt on more ponies in minutes and increase your throttle response for a quicker jump off the line and out of the corners.

Accufab is the Best!

Switch from the Accufab 75MM Race TB to the 90MM Race TB and picked up 7 RWHP and 4 RWTQ... My little 347 now puts down 406 RWHP and 386 RWTQ on 91 octane at the pump... Thanks Accufab!!!

    Well built, excellent performance, great looking throttle body.

    July 24, 2013

    My first reaction opening the box was a stunned "whoa". Pictures don't do the polish job on these throttle bodies justice. It is literally a mirror finish. Along with that, the throttle body is very robust and well built, and installs perfectly. Install time for any throttle body on these cars is a quick ordeal, but I had a few extra things to do, like find a new routing for the vent line off the valve cover, since this particular throttle body does not have provisions for one. Because of that, I rated it as an afternoon project, rather than "less than 1 hour", like most throttle bodies would be. Other goofy things to keep in mind is that, because the bore is so big, the idle air control motor mounting screws will have to be shortened, so they don't protrude into the air path. I also gave "bang for your buck" a 4 instead of a 5, simply because it does not come with a throttle position sensor. Ignoring that, it's tough to beat the price American Muscle sells these for. Most people are already going to have a TPS, anyway. Finally, performance gain is going to be based on what your current combo is, and what parts are acting as bottlenecks. Obviously, a stock 5.0 with the anemic stock intake isn't going to benefit from a 90mm throttle body. However, my current intake is designed for a 90mm throttle body and my ultimate build goals make a 90mm unit a good idea. Because of that, I gave it a 5 star, but individual results may vary.

    The name speaks for itself. You are not going to find a better quality, nicer looking throttle body than accufab. Only thing that could make it better is if it came with the tps sensor.
