Throttle Bodies

A bigger throttle body lets more air into the engine and sharpens throttle response. Granatelli Motor Sports builds drive-by-wire performance throttle bodies in billet and cast aluminum for GM LS engines (103mm, 105mm, 108mm, 112mm and 120mm), GM LT1, LT4 and LT5 engines (95mm, 103mm and 112mm), Dodge, Chrysler, Jeep and Ram HEMI engines (95mm), Hellcat and Trackhawk, and the Ford Mustang GT 5.0L Coyote (90mm, 2015-2017 and 2018-2023). Billet bodies come in natural or black, and some LS models in polished. Cast bodies such as the GMTBLS3M and GMTBHLCM are the lower-cost choice. You will also find the LT1/LT4 103mm adapter spacer plate, the 7" Dodge throttle adapter and replacement gaskets.

Throttle Body FAQ

What size throttle body should I get?

It depends on your engine and how much air the rest of the intake can move. A big throttle body on an otherwise stock intake gains little. If you are not sure, tell us your engine and mods. Call 1-805-486-6644, Monday to Friday, 8am to 5pm Pacific.

Billet or cast?

Both are drive-by-wire bodies built to fit the same applications. Billet is machined from solid aluminum and comes in natural or black, with polished on some LS models. Cast is the lower-cost option.

Are these drive-by-wire?

Yes. The throttle bodies on this page are drive-by-wire units for modern electronically controlled engines.

Will I need a tune?

It depends on the make. GM (Chevy LS and LT) and Ford throttle bodies require a tune. Dodge/Mopar HEMI throttle bodies, including the Hellcat and Trackhawk units, bolt on with no tune required. Questions about your combination? Ask us before you order.

Can Granatelli throttle bodies handle boost?

Every Granatelli GM LS and LT throttle body, billet or cast, is rated for up to 35 psi of boost. For a boosted HEMI or Coyote, call us with your combination before you order.

What warranty comes with a Granatelli throttle body?

90 days, with optional extended 1, 2 or 3 year coverage at checkout.

Fitting an intake as well? See the billet LS and LT intake manifolds.
