HPI M8 Throttle Body


HPi Milwaukee-Eight® throttle bodies are designed to allow more airflow over the stock 55mm throttle body.

HPi M8® units are offered in 58mm, 62mm and 70mm size.  The throttle body is manufactured out of 6061 billet material and include a fully CNC ported aluminum intake manifold. 

After stock M8 unit is sent in with work order form, HPi will test stock unit to ensure a working core has been sent in, then build the stock electronics into the new billet throttle body, and lastly re-test the upgraded throttle body and electronics to ensure a proper throttle opening curve.  This typically takes around 3-5 business days depending on parts in stock.   


Other features include:

  • Stock location for air cleaner bolt pattern

  • Cruise control compatible

  • Includes fresh rubber seals (utilize stock flanges & throttle body bolts)

  • Made in USA
