AMS Performance Stage 2 VR30DDTT Direct Injectors

The AMS Performance VR30DDTT Stage 2 Direct Injectors are designed to take your Nissan Z and Infiniti Q50/Q60 models from ordinary to extraordinary. If you’re looking to maximize your VR30’s direct injection fuel system, these injectors are the upgrade you’ve been waiting for. Factory injectors can hit a wall, especially when you start pushing the limits with ethanol-based fuels like E85. Recognizing this, we partnered with Nostrum High Performance to create injectors that not only meet but exceed your performance expectations.

Why Choose AMS Performance Direct Injectors?

These injectors are engineered as a direct fit replacement for your OEM injectors, meaning you can install them without any need for additional fuel rails or electrical adapters. The collaboration between AMS and Nostrum’s calibration teams ensures that tuners will find it easy to calibrate these injectors using the supplied data. This results in cold start and drivability characteristics that rival those of the original injectors, thanks to a next-gen spray pattern specifically designed for the VR30DDTT engine.
