Cutting edge Bosch EV14 technology

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

Multi-hole tip for superb atomization

Works with multiple fuel types, including E85

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

4x Denso to USCAR connector plugs, or USCAR pigtails
4x Denso bottom cushions
4x 12mm top hat extenders (import fit, 11mm diameter)

RE: RoadsterSport Stainless MX5 Miata Midpipe Part# 60-1328: I love the mid-pipe!! Not only is it beautiful, but it makes the sounds coming out of the 'race single' exhaust even better. The two go well together, and it mellows the decel drone a lot. I'm very happy with my purchase.

I just installed the Borla exhaust on the MX5. Sweeeeeeet! Thanks, Andy
