FlowForce ND2/ND3 High-Flow Injector Kit (Set of 4)

The fueling solution every ND2/ND3 Miata tuner has been looking for. On the ND platform, the factory injectors are the biggest constraint—once you unlock fueling, the car comes alive.

• +19% 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)

Why it works

These injectors maintain OEM spray targeting and valve behavior while increasing total flow by 19%. 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 19% to your injector flow rate/scalar in your tune, then dial in fuel trims and WOT lambda as usual.
