• Black anodized finish for durability and corrosion resistance
• Boost-resistant design handles over 25 psi in draw-through or blow-through configurations
• Powerful electric motors with unique throttle blade design prevent blade closure under high boost
• Utilizes late-model GM 6-pin drive-by-wire connector for plug-and-play installation
• Compatible with factory or aftermarket intake manifolds
• No need to transfer components from factory throttle body

Application: Designed for 2005-2017 GM vehicles with LS1, LS2, LS3, LS6, LS7, LS9, LSA, LSX, LQ4, and LQ9 engines including Corvette, Camaro, CTS-V, GTO, Trailblazer SS, and GM trucks/SUVs. Ideal for both naturally aspirated and forced induction setups, especially those running TVS, Whipple, or Roots-style superchargers.

Note: Custom tune is required for optimal performance. Trailblazer SS applications should confirm calibration compatibility before ordering.
