1999.5-2003 Powerstroke Stage 5 400cc W/Oil Mods (AP63803ADR5)

Description

Industrial Injection Stage 5 400cc race injector with internal oil modifications for 1999.5-2003 Ford F-Series and Excursion 7.3L Powerstroke trucks. A maximum-fuel HEUI injector built for serious horsepower builds — drag race, sled pull, and dyno work where the stock injector won't keep up.

The internal oil mods improve plunger response and lubrication margin at the extreme duty cycles a Stage 5 sees in competition. Each injector is fully calibrated and flow-tested on the IIS bench so cylinder-to-cylinder delivery stays balanced even at the high end of the fuel map.

Features
  • 400cc High-Flow HEUI Injector Design
  • Internal Oil Modifications
  • Fully Calibrated & Flow-Tested
  • Race-Ready Performance
  • Sold Individually
  • Part Number: AP63801ABR5
Notes
  • Race-only. Not legal for "On-Road," "Off-Road," or "Dual-Use" applications — dedicated competition use only. Compliance with state and federal emission standards is the consumer's responsibility.
  • Core deposit applies — keep your old injector and return it to recover the deposit.
