i'd say most would suggest the stuff from the dealership. THe only other plugs ive heard being used are the denso irridium plugs. Other choice for filters would be k&n, but there have been reports of fouled mafs with k&n filters. I'd go with the oe parts.

I would ditto that - I had K&N air filters but the SES light kept coming on although I cannot remember if the faults indicated fouled maf's or not.

When I replaced the air filters with OES, no more problems.

Sparkplugs are NGK BKR6EQUP.

If a board sponsor doesn;t carry them, try sparkplug.com, thay are quite cost effective.

Unless you can remove th over oiling condition prevalent in the K&N air filters, stick with OEM.

Pacific BMW does good on OEM pricing.
