Collection: LS 120mm Throttle Bodies
The Granatelli 120mm LS throttle body (GMTBLS120) is the largest LS throttle body in our lineup, built for 120mm-inlet intake manifolds such as the Granatelli ZILLA 120mm billet LS intake. It is a complete billet drive-by-wire assembly with the factory-style GM 6-pin connector, rated for up to 35 psi of boost and made in the USA.
A 120mm only pays off when the manifold, heads, cam or boost can use the air, so match it to the build. A tune is required after installation. Smaller manifold inlet? Compare the 112mm and 108mm options, or see all LS throttle bodies.
