P.S. If I'm understanding this correctly, the Bosch EV6 connectors have better fuel atomization
I just need an EV6 to EV1 connector like: https://www.amazon.com/dp/B0189E2G1Y/_e ... A7AI6P6VCK


Can you help me pick the correct size/flow Bosch injector for a 95 MPI intake manifold?

Thanks in advance for your assistance,
Jim

Since you have a Hesco AFPR, you have the flexibility to run a wide range of injectors and any of the following are potential candidates:

Ford Motorsport 24.0lb/hr @ 39psi (Part no. FMS-M9593-A302)
Bosch 0280155703 22.7lb/hr @ 43.5psi
Bosch 0280155849 24.5lb/hr @ 43.5psi (same as Ford XF1E-A5B)
Chevy LT1 24.0lb/hr @ 43.5psi (Part no. 17124248)
Accel 24.4lb/hr @ 44.1psi (ACC-150124)

EV1 and EV6 are the designations for the electrical connector which has nothing to do with the atomization. You are looking for a 4 hole injector. 4 nozzle injectors are available with both electrical connector configurations.

I have a Ford Motorsport 24 lb set with less than 5000 miles on them and 2 brand new spares for sale. PM me if interested

If you do end up needing an electrical adapter they are available.

I’m having connectivity issues now, at least half of them. Don’t know if it’s the adapters fault or my vehicles but I don't recommend you to use these. It is best to get the right ev1 fuel injectors for your vehicle or splice in the correct ev6 pig tails. By the way, I want automobile parts and accessories also. Does anyone know of any good online Black Friday sale or discount on coupons such as black friday coupons? Please let me know!
