Flow Force Miata 640cc Injector Kit - NA/NB


Flow Force Miata 640cc Injector Kit - NA/NB


The legendary injector kit supplying fuel to hundreds of high-performance Miatas and smiles to their drivers.

From lightly modified naturally aspirated engines to built motors with turbos or superchargers, the Flow Force kit is the standard for reliable power.

Why do they work so well? The off-axis, dual cone spray pattern injects fuel perfectly into the two intake ports for atomization that outperforms injectors at twice the price. Thanks to our tight flow matching at 2ms pulse width, they will support 300whp on pump gas, and still idle beautifully, making them the go-to choice for drivability and power on all but the most ludicrous builds.

Choose Flow Force for:

  • Cutting edge Bosch EV14 technology

  • Tight flow matching: within +/-1% static and dynamic (2ms pulse, idle conditions) flow rates for a smooth idle

  • Superb atomization thanks to their multi-hole disc tip

  • High performance with multiple fuel types, including E85

In the box:

  • 4x 640cc Flow Matched EV14 Injectors

  • 4x Denso to USCAR connector plugs, or USCAR pigtails

  • 4x Denso bottom cushions

  • 4x 12mm top hat extenders (import fit, 11mm diameter)
