I've got a stock '18 ZCP M3 and I'm looking to swap out spark plugs.
Over on FCP, they're listing ZR5TPP330A Bosch "OE" spark plugs for $6.15 a plug and claims that these are comparable to the ZMR5TPP330 "M" plug. While I want to believe that it's the same, has anyone actually ran with these Bosch OE plugs in our S55 motors?

While a bit over a hundred for a set of plugs isn't outrageous, just $36 dollars for all 6 for the same thing without the M badge is stupid cheap. Thoughts?
