Product Details

The Speedmaster LS throttle body adapter lets you match an LS-pattern throttle body to a different intake manifold inlet. It is useful for EFI swaps and custom induction builds. Each adapter plate is CNC-style machined from aerospace-grade aluminum. Speedmaster offers the line in straight and tapered through-hole diameters, so you can choose the transition that suits your throttle body and intake combination.

Key Features:

  • Aerospace-grade aluminum construction for strength and durability
  • Converts between LS 3-bolt and 4-bolt throttle body and manifold patterns
  • Tapered and straight bore designs for a smooth transition into the intake
  • Several bore-size and bolt-pattern combinations available within the product line
  • Designed for LS-style EFI throttle bodies and intake manifolds

Speedmaster adapters offer a simple way to mix and match LS throttle bodies and intake manifolds without replacing either part. Choose the option that matches your throttle body bolt pattern and intake opening. Check the specific part listing for what is included, since gasket and hardware details depend on the part number.
