DESCRIPTION
The fueling solution every ND2/ND3 Miata tuner has been looking for. On the ND platform, the factory injectors are the biggest constraint, and there have been no options in the aftermarket for a larger injector for the direct injection ND... until now.
- +18% more flow vs. stock ND2/ND3 injectors
- OEM-like drivability: spray pattern and valving characteristics closely match stock for easy tuning
- Flow-tested & matched in Tennessee for uniform cylinder-to-cylinder fueling
- Direct fit for ND2 (2019 "2022) and ND3 (2023+) 2.0L Skyactiv-G
- Supports pump gas and ethanol blends (with appropriate tune and fuel system capacity)
These injectors maintain OEM spray targeting and valve behavior while increasing total flow by 18%. The result is stock-like starts and idle with the headroom you need for bolt-ons, E-blends, and forced-induction builds.
Tuning Quick-Start
Tuning is straightforward because FlowForce ND2/ND3 injectors have similar flow and valving characteristics to stock. Start by adding 18% to your injector flow rate/scalar in your tune, then dial in fuel trims and WOT lambda as usual.
What s included
- (4) FlowForce ND2/ND3 injectors (matched set)
- Pre-installed O-rings & OEM-style clips
- Install & tuning guide + video link
How many cc's are these injectors?
For direct injection systems, we do not refer to the injector size in cc's like we do for traditional port injection systems. That is because for older port injection, all injectors are rated at a certain amount of flow (cc's) at an industry standard fuel pressure of 43.5psi. Even if the vehicle they'll be used in runs a different fuel pressure than that, all injector sizing is quoted at that industry standard so that it's easy to compare across different brands, etc. In comparison, direct injection engines run massively higher fuel rail pressures of a couple thousand psi, so to measure DI injectors by the old traditional standard would give meaningless numbers, and there isn't an industry standard in the aftermarket world yet for how DI injectors should be measured/rated. For that reason, to avoid confusion Flow Force chose to present things in a way that is much easier to understand and simply state the flow as a % increase compares to the stock injector.
