17lb or 19lb for A Stock 325i

[Quinthirty]

I run the plastic body Bosch #17 design III. They gave me more low end torque, better gas mileage, and better idle. I recommend them.

Thanks for all the replies, guys.

Anyway, did you have to change the terminals for Design IIIs? Is it plug and play?

Yeah, definitely will do my research about replacing my stock injectors with some stock M50 ones.

I drive an auto 325i and put an ebay chip on my 173. it gave my m20 life and increased fuel efficiency. then upgraded to 17lb injectors from M50 and rebuilt and cleaned it... my car is alive and kicking. It totally made a big difference. It is more responsive now,despite being auto. I love to hear it roar.

Thanks, I'm going to add it to my project list...

Was it plug and play? You didn't need to splice the wirings on the injectors?

No, they are plug and play.

For $132 shipped. New pintles, cleaned and flow matched.

Interesting. I've got a Conforti chip, so should I run 19# injectors vs. 17#? I noticed Mark D doesn't even list a 17# option.

Would I notice a difference between the Mark D chip with 19# injectors vs. the Conforti with 19#?

Read my new thread its a few below this one

Basically you want an injector that offers better atomization with the same flow rate (150cc/min)

The M50 injectors are slated at 3.5bar, but the stock is at 3.0 bar. What is the effect of having a difference in bar ratings?

3rd calculator does pressure adjustments

pretty sure they're rated 17# at 3.0 bar, but they're run at 3.5 bar on M50s. most injectors are rated/tested at 3 bar.

19lb from m30 (black ones) + m30 afm + Ebay chip would be a good combo ..

I plan on going this route but whats the difference between the green m30 injectors and the black ones?
