The Standard for High Performance Miata Fuel Injectors

Track-Proven

Supports up to 260whp on E85, 300wph on pump gas

better-than-stock idle

 
 

Cutting Edge Bosch Technology

 

640cc @ 3 bar with OEM, unmodified tips provide excellent control and atomization, resulting in the best of both worlds: big power potential with the precision and flow matching required for a smooth idle on small engines.

 
 
 

Flow Tested and Dynamically Matched

 

Flow Force Injectors are tested at wide open flow and at a simulated driving conditions. We then match them into sets with static and dynamic flow rates ±1%.  With each cylinder getting nearly equal fuel, you get a smoother idle, and can tune more aggressively without going lean in one cylinder under boost.

 
These Bosch design 4 injectors are without a doubt some of the best I have ever flow tested. They are super precise.
