yes that is the recommended flow rate for the 3.2L, I had the same injectors in my C280 with a 3.2L. the only thing is that those are not accels, accel injectors are yellow. and you will need the high impendance ones, low impendance ones are mostly used on aftermarket, standalone systems.

is your m104 force fed? in not, 24lb are the perfect upgrade. anything higher will throw off the O2 sensor and you will run overly rich constantly. believe me, I tried 30lb, then 26,and finally the 24lb worked flawlessly. the throttle responce was significantly better.

that sounds about right, which is why you dont want to go with much higher flow rates that stock on a OEM dme.
do a search, I talked about injector upgrades quite a few times in the past.

they do look the same, but they are not. I would recommend you put the oem ones on just to be sure.

I dont think so because the same happened when I installed accels on my dad's E500. also, another member, cklasse, had also installed them on his slk230k and he had the same issue. If you want, try installing the injectors with their orings, and if it doesnt leak, return the oem ones for a refund.

Its best if you can get the line fabricated locally, most air and hydraulic shops can do it and it shouldnt cost more than $50.

oh, I thought that was the replacement line. do the fittings have the same threads as the oem line? If the line has only one threaded end and one open, that it should work.
