Granatelli 105 mm DBW LS Throttle Body – Black
TUNE MAY BE REQUIRED
Unleash the full potential of your LS-powered build with the Granatelli 105 mm Drive-By-Wire Throttle Body. Engineered for serious horsepower and built to thrive under extreme boost, this throttle body delivers massive airflow, lightning-fast response, and bulletproof reliability. Whether you're running high compression, boost, or both—this is the upgrade that won’t hold you back.
Fitment
This 105 mm drive-by-wire throttle body is designed for high-performance GM LS and LSX applications using a 6-pin late-model GM-style DBW throttle connector. It’s ideal for:
- LS2 / LS3 / LS7 / LSX crate engines
- L76 / L99 / L92 / LSA / LS9 (with appropriate intake)
- Aftermarket intake manifolds with 4-bolt throttle flange (FAST, Holley, MSD, etc.)
- Supercharged or naturally aspirated builds
- Fits most GM vehicles using 2005+ DBW throttle systems with 6-pin connectors
Note: A throttle body adapter may be required for some intakes. Always confirm intake compatibility before purchase.
Key Features
- 105 mm bore delivers dramatic airflow gains across the entire RPM band
- High-torque stepper motors handle 25+ psi boost, stopping throttle slamming under force
- Unique blade design keeps you in control during high-boost pull-downs
- Direct bolt-on fit with supplied adapter—no transfer of parts, compatible with factory and aftermarket intakes
- Late-model GM 6-pin connector included for plug-and-play installation
- CNC-machined 6061-T6 billet for precision, durability, and zero shortcuts
- Sleek black finish looks right at home under a carbon or OEM-style LS hood
Performance Notes
- TUNE MAY BE REQUIRED — especially with forced induction or aggressive setups
- For Trailblazer SS applications, please call prior to ordering to ensure proper calibration compatibility.
This isn’t just another bolt-on—it’s a performance essential for anyone pushing the limits of their LS setup. Whether you're chasing 9s at the strip or just want the sharpest throttle feel on the street, the Granatelli 105 mm throttle body is built to deliver.
