ODULA BIG-BORE Throttle Body for Mazda RX8 (Series 1 & 2, 2003-2012)

Improve airflow into the engine with a larger throttle body that supports higher power levels and enhances throttle response.

$750

This high-precision ODULA throttle body for Mazda RX8 Series 1 & 2 models (2003–2012) is CNC-machined in Japan to increase airflow without compromising idle stability or drivability, delivering a meaningful bump in mid-range torque and response.

  • Throttle diameter enlarged by 2 mm, increasing intake air volume by around 10%
  • Noticeable gains in torque and power particularly between 3,000–5,000 rpm
  • Machined on high-precision equipment to ensure smooth operation and stable idle
  • Optional titanium shaft and butterfly available for even snappier response
  • Requires trade-in of a standard, functioning throttle body as a core

You’ll feel a much more urgent and linear mid-range, with the familiar flat spot significantly reduced and acceleration feeling stronger and more rewarding in everyday driving.
