Throttle Body Adapter - Version 2

Throttle Body Adapter - Version 2

The Skunk2 Ultra Street manifold is our favorite solution for the K series Miata swap. This manifold's plenum can be unbolted and flipped upside-down, making it perfect for a RWD vehicle.

However, in order to make this manifold truly plug-and-play, we had to design this throttle body adapter and throttle cable bracket. Since an upside-down K series throttle body won’t fit, our adapter allows you to run a B series throttle body in its place, with the proper orientation. In addition, our adapter features:

  • A Miata-specific throttle cable bracket (designed for the shorter NB cables)
  • K series MAP sensor port
  • B series throttle body bolt pattern so you can use the reliable B/D/H/F style TPS

Our Version 2 adapter is now designed to accommodate our new 74mm throttle body. The inlet is tapered from 74mm to 71mm, allowing a 74mm throttle body to adapt to the Ultra Street manifold.

This adapter solution takes the guesswork out of installing this manifold and throttle body combo in your Miata.
