2006 M5 what kind of spark plugs should use.
 

I have a 2006 E60 M5 just reached over 60,000 km and it's asking me to replace the spark plugs.

should I use what the deler recommends or is there anything better out there.

Thanks

Lots of stuff out there.
I would stay with what the dealer recommends.
But you probably don't need to buy it from them. Find it elsewhere.

ngk plugs only.
