Frequently Asked Questions About the G37 ID1050-XDS Injectors

Is the Injector Dynamics kit 1050.48.14.R35.6 a direct-fit for an Infiniti G37?

This kit is specifically engineered for the Infiniti G37. The 48mm injector length ensures proper seating between the intake manifold and stock fuel rail. It features a 14mm top o-ring designed to seal perfectly in the factory fuel rail bore, making it a true drop-in installation without any spacers or modifications required.

How much wheel horsepower (WHP) can the ID1050-XDS injectors support on a G37?

The ID1050-XDS injectors flow 1050 cc/min at 43.5 psi, providing ample fueling for naturally aspirated or turbocharged VQ37VHR builds. They can reliably support builds up to ~500 WHP on pump gasoline or ~550 WHP on E85, assuming an adequate fuel pump and proper ECU tuning.

Do the ID1050-XDS injectors connect directly to the G37 factory wiring harness?

Yes, these injectors feature USCAR-style connectors compatible with the Infiniti G37 factory wiring harness. They allow plug-and-play installation without any cutting, soldering, or wiring modifications.

Why does this injector kit use a 14mm top o-ring for the G37?

The 14mm top o-ring matches the stock fuel rail bore, ensuring a leak-free, OEM-quality seal. Using a different o-ring size would not fit properly and could require an aftermarket fuel rail.

How do the ID1050-XDS injectors maintain smooth idle and drivability on the G37?

These injectors utilize Dual Slope Matching technology to provide highly linear fuel flow even at minimal pulse widths. This prevents rough idle and inconsistent fueling, delivering smooth OEM-like drivability while supporting high-performance engine upgrades.
