These are new 102mm throttle bodies for GM LS series engines with the standard 4 bolt bolt pattern.
- LS1 or Vortec Idle Air Controls (IAC) fit without any extra machining required.
- OEM Throttle Position Sensor (TPS) will fit without modifications.
- Throttle plate screws are installed with Loctite.
- Adjustable throttle stop.
- Stainless mounting bolts and TPS/IAC screws are included.
- Vent tube is shown facing forward, but can be re-positioned as needed.
- 4 bolt mounting pattern – an adapter would be needed if you want to use one with an older 3 bolt manifold.
We also have these available in a black anodized finish in another listing.
