hey guys, how you change the spark plugs in a 525i?

[Torque]

all 92+ 525 will have 6 coils. Its not so much a "style" as a "technology". No point in using a distributor and spark plug wires when COP technology was available.

All m50 525s had individual coils ... so 91 included.

I know that all M50 are COP, but not all 91 are M50.

I know that all M50 are COP, but not all 91 are M50.

I've got a 10/90 build date M50 525im. Check realoem or the ETK and try the pre-91 build dates (U.S. vehicle). At some point before 91, the M50 became available. Were they both (M20 and M50 build in the same year?)
