My 2009 128i convertible is coming up on 100k miles so I figure it's time to change the plugs. I checked getbmwparts and the OEM plugs are $16.25 (each?). Does anyone have recommendations on replacement plugs? Should I absolutely stick with BMW plugs or are there cheaper plugs which are just as good or better?
The car is a daily driver, no track driving.
This is the plug at getbmwparts:
