Anyone know the resistance (reactance for you techs) values for the Bosch 0221504470? Been looking around for the specs but I’ll be darned if I can find em. I’m troubleshooting intermittent misfires on cylinders 1&8 fwiw

Got some hits for other bmw’s but not this specific one.

Measured the 6 coils I have in storage as spares and came up with:

0.7-0.8 Ohm Primarys

Varying secondaries
3.75MOhm - 5.3MOhm

Most of the coils are around mid to high 4’s

Cheers
