Anyone ever put a performance coil on an M30?
Been reading some stuff on high performance coils...sounds like there might be something to be gained above the 4.5k to 5k RPM range with a high perf coil ala a Jacobs or similar.
Don't know much about the BMW ignition system and how much "performance" it leaves on the table. Reading suggests that a tweeked coil would allow larger plug gaps...
Or...alternative thought - how long does a stock coil really last for? Do they "fall off" over time or do they run at 100% and then just die?
thx!
