MF piece on JCW plugs

so for those of us w/ the jcw tuning kit we're supposed to replace the plugs ever 10~15k miles? that seems pretty crazy to me

In my experience, 15k is pretty much in line with a lot of other high-performance vehicles on the market. That was also the interval I used in my E36 and E46 M3's.
