20.5 lb/hr Hi-Z Injector 1990-92 C4/ZR1 (Primary)

20.5 lb/hr Hi-Z Injector 1990-92 C4/ZR1 (Primary)

TYPICAL APPLICATIONS:

• 1990-1992 ZR1 Corvette VIN J DOHC Primary Injector

Performance advantages over pintle injectors (i.e. Ford / Bosch & Accel types) as listed by Delphi:

• The flat mating surface ensures that no excess fuel is present to evaporate and therefore, no deposits or clogging can occur.
• Compatible with alternative fuels (i.e. E85, Methanol)
• Longer service life
• High-speed disc action allows wider dynamic flow range for improved idling
• Quieter operation
• Revolutionary disc design resists build up deposits which can affect fuel flow.
• No Fuel leakage for quicker starts
• Grease supplied to lubricate o-rings prior to installation
  

TECHNICAL INFORMATION

Injector flow rates are based on testing with n-Heptane test solvent (0.6855 g/ml). U.S. EPA emission test gasoline 40CFR86.113 (0.735g/ml) flows in most common injector designs at about a 3 to 4% higher rate than n-Heptane. A ratio of 1.035:1 can be used when converting the flow specifications above.

This high-impedance injector will work with all factory ECM/PCM injector drivers.
