Thank you. You have rated this product.

If you are looking for superior idle quality but you do not need monster 1000cc injectors for your project, look no further!

These high performance, high capacity, long body EV14 injectors are plug and play for the 2006-2015 Mazda Miata (NC)

Cutting edge Bosch EV14 technology

Flow matched within +/-1% static and dynamic (2ms pulse, idle conditions) flow rates for a smooth idle

Multi-hole tip for superb atomization

Works with multiple fuel types, including E85

Plug and Play for NC miatas
These EV14 injectors are the go-to choice for high performance naturally aspirated builds, low pressure e85 forced induction, or moderate pump gas builds. Thanks to our tight flow matching at 2ms pulse width, they will support 300whp on pump gas, and still idle beautifully.

Kit Includes:

4x 550cc (at 3 bar) Flow Matched EV14 Injectors
1x dielectric grease
Bosch Type IV Fuel Injector Info:

Length: 60mm O-ring to O-ring
Diameter: 14 mm
Resistance: 14.5 Ohms (high resistance)

Hi Brian, I just bought a heatshield and a cruise control relocation bracket for my '95 Miata from you. It is in the mail now. Thanks for such fast service. (My cruise is just wrapped up in a microfiber shoprag at this time!)
