MILWAUKEE 8® THROTTLE BODIES
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)

*Please Read before sending in your stock unit for upgrade:
Unit must be stripped of all gaskets and mounting hardware (fuel rail, map sensor, injectors) or there will be a $50 disassembly fee. M8's do not require stock intake to be sent in. Do NOT remove internal electronics
Make sure the unit is packaged in a sturdy box and secure with bubble wrap so it is not damaged in transit. Any damaged throttle bodies will be returned as is. It is smart to insure your package with the shipping company. You do not need to send in the stock manifold. You will not get back the stock throttle body, the stock unit will be scrapped after we strip out the electronics.
Throttle body must be in good working condition before sending in. If you aren't sure if it works, don't send it in!
M8® MANIFOLD ONLY
Purchase a Milwaukee Eight® HPi aluminum, CNC ported intake manifold only. HPi's M8® intake manifold will bolt to a stock throttle body with a slight step, no exchange needed, as it's just the manifold upgrade. These fly off the shelf, so allow up to 2 weeks ship time, depending on our current stock. The manifold only will include an o-ring and two intake seals. Utilize your stock flanges. *International shipments will be sent an additional money request for shipping fees.

This add on option adds on an additional $150-$160 and also an additional week lead time. Popular anodize colors are Black, Gold, Red, and Blue. Specify add on and color on downloadable pdf order form above.
