For more powerful and enjoyable, I would look into getting a Magnaflow exhaust sytem (or some other reputable brand), K&N drop in filters (just don't over oil them) and have your ECU tuned by a tuning company (I have heard good things about Logic Lab Tuning) but only after doing exhaust and intake mods. You may also want to look into a sprint booster device to add more of a fun factor to the driving experience.
i have some questions and i hope i find answers here
first of all i say that i love my ML320 and thats why i want to spend moeny on that exact car and not buy newer one...
so the first question is how difficult or if is even possible to enlarge engine displacement from native 3200 cc to 3700 cc as happends on facelifted models M350,
the other question is if is possible to mount 7g tronic gearbox instead of an 5g,
have anybody any other good idea how to "update" ml320 to run more powerfull, comfortable, enjoyable?
Thank you all
