Package: 1x
Connector: Bosch USCAR
Length: 60,65mm - EV 14L (Long) 
Injector tip: 11mm
O-ring top: 14mm Viton
O-ring bottom: 14mm Viton
Body diameter: 16mm
Impedance: 12 ohm
Spray pattern: 30 degrees 2 jets

Fuel: E85 / M100 compatible and can handle other standard fuels due to the stainless internal parts. ATTENTION! If the injector is to be run on methanol, it must be run through with regular fuel after use. These injectors must not be in contact with methanol over more extended periods.

Max flow measured static in test environment
29 PSI (2 bar) 420cc / min = 40 lb / h
43,5 PSI (3 bar) 510cc / min = 49 lb / h
58 PSI (4 bar) 588cc / min = 56 lb / h
78,5 PSI (5 bar) 657cc / min = 63 lb / h
88 PSI (6 bar) 732cc / min = 70 Ib / h
101,5PSI (7bar) 792cc / min = 75 lb / h

Please note that test environment versus practical use can vary widely depending on peripheral equipment and other technical factors. However, this is excellent information on what to expect from the injectors and essential information when choosing other components in the fuel system, such as fuel pump, fuel pressure regulator, and fuel filter.

Flow matching
These injectors are shipped with factory tolerances unless you choose to have them flow-matched. We always recommend flow-matching before delivery. Factory tolerances of the injectors differ, and you have to run them unmatched with wider tolerances or compensate for this when tuning the engine management system. How much they differ from the factory continuously varies.

Flow-matching is done with our top equipment when you add this option! In addition, we include documentation and certificates with your new injectors.
