Would putting a MSD system into an e30 be beneficial? Or does bmw already have its own version stock? mainly thinking about it on a 325is.

Somewhere around 12-14lbs. of boost some people have had the need (even with colder plugs).
Other than that, I've never heard of anyone with spark problems.

A MSD wouldn't only be used for supercharged engines, it also produces a cleaner and more thorough burn in a naturaly aspirated engine as well.'87 alpine white 325isComment

Looks like you already made up your mind.
No, bmws do no come stock with multiple spark.

Not really made up my mind, just wanted everyone else's take on it.'87 alpine white 325isComment

It may help with smoother idle, and better gas mileage. But all gains would probably be very minimal.

My opinion is that if you don't NEED one, you don't need one.
Yeah, probably a better idle and that's it. Now if you have 15psi going through your engine, I would get one.
Don't forget to re-gap if you do. Sometimes people forget.
Post an update when you have it installed. :o

Well, ive done it, so ill comment. Imo, unless you have aquired one, or can get one cheap dont bother spending your money. It helped smooth idle on my eta, but the 'e' is slightly different from the 'i' in terms of engine software. Other than that, no hp increase, no visual spark improvement looking at my plugs, and no noticable increase in fuel economy. I took it off because my ignition system took a crap probably due to vibration that killed the msd box.
This was an msd 5 that I took off of my 49 chevy 327 when I switched to heiOld and improved:
