The AMS Performance VR30DDTT Stage 1 Direct Injectors are the perfect upgrade to get more out of your VR30’s direct injection fuel system. The limitations of the factory injectors become evident even at relatively lower horsepower numbers, especially when using ethanol-based fuels like e85. We recognized early on in our development of the Infiniti Q50 and Q60 platforms with the VR30 engine that we would need to provide more fuel to support more power. Working together with Nostrum High Performance, an industry leader in fuel system technology, during the development of this component is the reason our customers know that they can rely on the AMS VR30 Direct Injectors to be the best built, best performing on the market.

The AMS VR30 Stage 1 Direct Injectors have been engineered to be a direct fit, OEM injector replacement that requires no fuel rail or electrical adapters to install. The AMS and Nostrum Calibration Teams have also gone the extra mile to make sure the Stage 1 Direct Injectors are also easy for tuners to calibrate with the supplied injector calibration data. Our combined product engineering and calibration data together allow the AMS Stage 1 injectors to achieve cold start and drivability characteristics on par with the OEM injectors by retaining a factory spray pattern ⁠— validated experimentally and via Computational Fluid Dynamics.

The AMS VR30DDTT Stage 1 Direct Injectors are derived from a brand new OE manufacturer's direct VR30DDTT HDEV5 injector cores. As these injectors come via the OE supply chain they have VR30 specific, factory correct, overmold, and fuel rail features allowing for a perfect OEM fitment. During the entirety of the Nostrum manufacturing process, each injector and its subcomponents are serialized, QR-coded, and tracked to allow for full traceability. AMS and Nostrum are so confident in the construction of these units, a limited lifetime warranty against manufacturer’s defects is included at no additional cost to insure your investment.

What sets this and every AMS component apart from the competition is our rigorous battery of R&D testing. The AMS VR30 Stage 1 Injectors have been tested for thousands of miles in multiple vehicles, including countless 1/4 and 1/2 mile runs, before being given the green light to release to the public. Our AMS Engine Calibrators have spent hundreds of hours testing these injectors in vehicles in order to refine them with Nostrum High Performance for maximum fueling performance and vehicle drivability. In addition to this research and development testing, all AMS VR30 Injectors are bench tested, including 100% static flow testing and multi-point dynamic testing, by Nostrum. The injectors are then batched dynamically with a +/-5% variation in flow and are serialized with specific data packages for direct calibration before shipping as part of their extensive quality control process.

Please Note: In order to take full advantage of these AMS Stage 1 Direct Injectors, specific calibrations to your ECU tune file will need to be made. Once the injectors are installed, an appropriate ECU calibration must be loaded before the engine starts and runs or damage can occur! Horsepower numbers are appropriate and can vary significantly depending on numerous factors such as your ambient temperature, elevation, fuel octane, and fuel quality, among many others. The advertised numbers herein are based on optimal conditions and utilizing proper supporting modifications but are generally attainable results by an average customer. Your results may vary.
