Z1 Kinetic Fuel Injectors by Nostrum are a drop-in replacement injector for the VQ35 engine found in the Nissan 350Z and Infiniti G35. These injectors are engineered to provide your engine with proper fuel flow, are Z1's first-choice for forced-induction applications, and can support power levels in excess of 800whp with a return-style fuel system.

Their patented nozzles allow multiple jets of fuel to collide with one another, utilizing kinetic energy to produce superior atomization of the fuel and shorter liquid lengths, preventing film accumulation on the surfaces of the cylinder walls and the piston. The injector spray pattern has been optimized using state-of-the-art CFD technology. By analyzing intake manifold design, piston profile, and cylinder head geometry, Nostrum was able to produce an injector that provides a cleaner burn while optimizing cold starts, idle quality, and mid-range performance. This is the ONLY aftermarket drop-in fuel injector that has been engineered specifically for the VQ series engine! Included with every set of injectors is a detailed test sheet showing the flow rate and various other test parameters (pulse width, latency, etc) that are verified before shipping.

These injectors are capable of supporting power levels in excess of 700whp, however, it's important to remember that the required flow rate depends on other factors such as fuel ethanol content, boost levels, turbo/supercharger size, air:fuel ratio, and fuel pressure. For best performance, we recommend all forced induction applications upgrade to a return-style fuel system. If you're unsure what works best with your specific build, contact us for assistance!
