Granatelli 103MM Throttle Body, Black Aluminum

*Fits: 2010-2015 Camaro SS, ZL1

Granatelli Motor Sports, established in 1989, is proud to Introduce their 103MM Drive-By-Wire LS series CNC throttle bodies precision-machined from 6061 billet aluminum to exceed the demands of required increased airflow on all drive-by-wire LSX performance applications, both naturally aspirated and forced induction. Our 103mm throttle body, with the industries strongest electric motor are as tame as stock and can still handle upwards of 25 lbs of boost in a draw or blow through configuration. The GMS unique throttle blade design and super powerful electric motors prevent the throttle blade from being forced closed under high boosted applications. The Granatelli Motor Sports 6061-T6 CNC precision machined billet throttle bodies are designed to exceed the requirements of increased airflow on the "drive-by-wire" LSX performance engines when using factory or aftermarket manifolds. This is a must for anyone running a TVS, Whipple or Roots style supercharger. Utilizes the late model GM 6-Pin connector.

This kit requires a 103mm or larger intake port*
For aftermarket style intake manifolds that require the throttle body to be flipped, an optional extension may be required.
