HardDrive Parts EFI 55mm SE Intake Manifold For Harley Milwaukee-Eight

A restrictive stock intake can hinder the performance of a Harley M8. The HardDrive EFI Manifold addresses this issue with a substantial 55mm bore and smooth runners that enhance air delivery to the engine. This bolt-on power upgrade results in a significant increase in horsepower, allowing the rider to experience an immediate difference upon acceleration.

Features:

OEM Style Replacement Manifold with smooth designed ports
Cast aluminum construction
Fits the stock throttle body
Recommend replacing intake flanges and intake seals upon install (sold separately)
Replaces OEM 27300167

Note: All models require ECM calibration with Screamin' Eagle Pro Street Tuner or dealership installed Screamin’ Eagle calibration for proper installation.
