PF M8 Fuel Injectors

Precision flow. Fast response. Built for big horsepower.

Serious horsepower needs fuel delivery that keeps up. PF high-performance injectors are built for high-output Gen 1 and Gen 2 Milwaukee-Eight engines, from aggressive naturally aspirated builds to turbocharged and supercharged applications. Each set is flow-balanced and matched within 1% variance, so every cylinder gets the same fuel.

What You Get:

• Individual flow-data report with each matched pair
• Static and dynamic flow data at 3.0, 3.5, and 4.0 BAR, plus flow characterization at 15%, 50%, and 100%
• Injector dead-time (latency) data for accurate fuel calibration
  
• Superior atomization for better combustion and throttle response
• Consistent low-pulse-width performance for smooth idle and low-RPM running
• Plug-and-play US-CAR connection, no wiring modifications on compatible applications

Fitment:

• Harley-Davidson Milwaukee-Eight (M8), Gen 1 and Gen 2
• Big-bore 131", 139", 143" and larger engines
• Naturally aspirated, high-compression, turbocharged, and supercharged builds

Available Flow Rates:
