535i-2008 spark plugs
Hi
I'm almost hitting 90K soon and I'm thinking to replace the following:
1- spark plug & direct ignition coil (BOSCH). The question I have; do I need to change the ignition coil too. Or spark plugs is good enough.
2- Air Cabin & Engine air filter. Do I need to do that since they are looking clean ?
I would appreciate your advice.
Thanks

Unless you're getting a misfire, the coils should be OK. FWIW, I have 210,000km on my original 11/07 date code coils. The spark plugs were extremely worn (see pic) but I didn't get misfire until I put a JB4 tune on it around 170,000km and boosted it to 13psi.
Air filters are cheap enough, just replace them.
