Has anyone found plain copper core spark plugs for the N51 engine

Hello, these days manufacturers have come up with all kinds of coatings to prevent corrosion and push spark plug life to over 50k miles but I personally like the whole exercise of replacing them at shorter intervals.

While it really isn't about the price, the NGK LZFR6AP11GS are about $12 each and I have found the BOSCH FR7NPP332 are about $9 while plain copper core BOSCH are usually $2 each, so you can replace them a lot more often without significant cost

I just bought the Bosch FR7NPP332 (N52) and will be installing in the spring. $7.16 on Black Friday sale at Bav Auto.

Trust me, this is a really stupid idea. Just use oe recommended plugs...
