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:

Note: A throttle body adapter may be required for some intakes. Always confirm intake compatibility before purchase.

  • 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

  • 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
