Bosch 72 lb/hr High Impedance Injector



Out of stock

SKU: INJ_Bosch72 Category: Brand:


Modified Bosch/Ford 72 lb/hr injectors. These have a 60 mm O-ring to O-ring length and 14 mm O-rings for fitting most American V8s, as well as many other German and domestic applications. These injectors are enough to feed 110 hp per injector, naturally aspirated. They use EV6 connectors, so 5.0 Mustangs, Chevy TPI motors, and some others will need adapters or replacing their connectors with EV6 style connectors.

Some engines these injectors will fit (for factory intake manifolds) would include:

  • Ford 5.0 (Windsor) V8s
  • Chevrolet L98 / TPI motors and 1990s LT1
  • Chevrolet LS1
  • BMW M20, M30, and M50

Note that many later LS engines used shorter injectors, particularly truck motors. For engines after the LS1, you will need to check injector length before ordering.

Sold individually.

How much horsepower will these injectors support?

  • We recommend this for engines making up to 110 hp per cylinder naturally aspirated or 95 hp per cylinder on forced induction. These numbers are for gasoline; the maximum horsepower will be lower on alcohol.

    Q Are these methanol compatible?
    Asked by Ron

    They're not really meant for methanol. I'd recommend flushing them out with gasoline after every race if you use this fuel.
