Best spark plugs for Z3M S50 ?

Post by Robin » Tue 29 Aug, 2017 13:46

Hello
I tried to search forum for 'spark plug' but doesn't seem to work.
Anyway, after running rough for a few miles my car now seems to only be running on 5 !
I hope unburned fuel didn't cook the cat as I limped home !
Can anyone recommend best spark plugs for Z3M S50 ?
Wondering if there's any better than OEM's
Thanks

My view is anything 'M' related is already well spec'd so I'd stick with OEM. Maybe you had a duff one?

Probably not a faulty one.
The plugs have done 10s' of k's of miles & they don't last forever. Someone said it may be the coils.
Getting it checked out tomorrow by local garage. The have code reader that will let them know which cylinder misfire is on

Garage has determined that misfire's due to a faulty coil pack. The bulk head end one that is more inclined to get drips of water on so most often packs up.

Yep, they don't last forever. happened to me twice and usually at the most inconvenient times. I now carry a spare in the boot along with my Peake code reader.
