Description
Give your LS engine the airflow it has been asking for. The Granatelli 105mm billet Drive-By-Wire throttle body opens up the intake path with a substantially larger bore, quicker electronic throttle response and a boost-capable design built for serious street and race combinations.
The Granatelli GMTBLS105 105mm Drive-By-Wire Throttle Body is precision CNC-machined from 6061-T6 billet aluminum and finished in sleek black anodizing. Its large 105mm bore provides increased airflow capacity for modified GM LS engines while maintaining electronic Drive-By-Wire throttle control.
Equipped with a high-torque electronic motor and reinforced throttle-blade assembly, the GMTBLS105 is engineered for naturally aspirated combinations as well as high-boost supercharged and turbocharged applications where airflow and throttle stability become increasingly important.
BIG AIRFLOW. FAST RESPONSE. BUILT FOR BOOST.
105MM BORE • ENGINEERED FOR 25+ PSI

Performance & Tuning Notice: A tune may be required for proper operation and optimum performance, particularly on boosted, highly modified or custom engine combinations. Proper calibration helps ensure correct throttle response and drivability.
105mm Bore for Serious LS Airflow
As engine output increases, airflow demand increases with it. The Granatelli 105mm throttle bore provides additional inlet area for engines that have outgrown smaller factory throttle bodies, helping reduce restriction at higher airflow levels and allowing compatible intake systems to breathe more efficiently.
Built to Stay in Control Under Boost
High boost pressure places additional load against the throttle blade. Granatelli addresses this with a high-torque stepper motor and reinforced blade design engineered for 25+ psi, helping maintain stable electronic throttle operation in demanding forced-induction applications.
Precision Billet Aluminum Construction
The GMTBLS105 is CNC-machined from durable 6061-T6 billet aluminum for strength, accuracy and long-term durability. Its black anodized finish adds protection while giving the throttle body the clean, aggressive appearance expected on a high-end LS engine build.
Plug-and-Play GM Drive-By-Wire Control
The electronic throttle assembly is designed to work with compatible late-model GM 6-pin Drive-By-Wire systems. This allows the larger 105mm throttle body to retain modern electronic throttle functionality while dramatically increasing available airflow capacity.
Street, Strip & Boosted Performance
The 105mm size is an excellent choice for modified street cars, naturally aspirated performance engines, large-displacement LS builds and forced-induction combinations. Whether your setup uses a supercharger, turbocharger or high-flow naturally aspirated intake, the GMTBLS105 gives the induction system additional room to breathe.
Compatible GM LS & LSX Applications
Designed for compatible GM LS applications using the appropriate late-model 6-pin Drive-By-Wire throttle-control system. Common engine families include:
