Frequently Asked Questions About the G37 ID1750-XDS Injectors

Why choose ID1750-XDS injectors for a turbocharged Infiniti G37?

The ID1750-XDS delivers the extreme flow rate (1750cc) needed for high-power, forced-induction VQ37VHR engines. They maintain precise control and linearity, which prevents rough idling and ensures reliable tuning for maximum power on your G37.

Is the ID1750-XDS (1750.48.14.R35.6) a direct replacement for the G37?

Yes, this specific Injector Dynamics part number is engineered as a direct drop-in for the Infiniti G37. It features the correct o-rings and overall length to fit the VQ37 fuel rail assembly without the need for modification.

What is the required tuning process after installing the 1750cc injectors?

A professional custom tune is non-negotiable due to the high flow rate. The tuner must adjust the ECU's fuel map and compensations to ensure accurate fuel delivery, crucial for maintaining safe air/fuel ratios and peak performance.

Can I safely run E85 fuel in my G37 with the ID1750-XDS?

Yes, the ID1750-XDS is manufactured with stainless steel internals and compatible materials, making it fully safe and durable for use with E85 (ethanol), methanol, and standard gasoline on your G37.

How does Injector Dynamics guarantee performance consistency for the ID1750-XDS?

Every injector set is subjected to a rigorous flow-testing and matching process, providing detailed data to the tuner. This individual characterization ensures near-perfect consistency across all cylinders for a stable and efficient high-performance tune.
