  • LS Throttle Bodies with Simple Installation & Tuning

    Whether running a turbo, supercharger, or big ol' cam, Holley Throttle Bodies are maximized for your application with the largest bore available & the ultimate air valve for GM LS engines. An all-new design boasts a 95mm or 105mm bore for wide-open throttle (tapered option offers low-RPM drivability for the street), idle bleed adjustment, PCV passage defeat valve, and throttle position sensor clocker that helps maintain proper idle voltage (especially on modified engines).

  • Cable-driven throttle plate
  • Aluminum construction
  • Anodized black
  • Idle bleed screw adjusts idle without affecting throttle position or TPS voltage at idle
  • PCV passage valve setting provides easy PCV block-off on forced induction applications (no need to tap & install plugs to block PCV)
  • TPS "clocker" prevents idle adjustment issues related to throttle sensor by allowing sensor to be rotated back to ECU's required idle voltage range

  • Some parts are not legal for use in California or other states with similar laws / regulations
