The VQ35DE G35 is one of the better naturally aspirated V6 platforms available, and standalone ECU support for the manual transmission variant makes it better still.
The Infiniti G35 VQ35DE runs a proven, well-regarded V6 that responds to proper calibration, but the factory ECU keeps it conservative and inflexible. The Tuned By Shawn PNP Wiring Harness Kit for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.

- Throttle response that's direct and immediate, not filtered through factory drive-by-wire logic

The Details
