I have BM3 Stage 1, 93 with stock plugs (67K miles - plugs were changed at 44K miles). It a 2014 with Comp Package, no mods except carbon filters delete and Bootmod3 Stage 1 93.
Car ran 11.40 ET @ 124.53 mph with the stock plugs last month. Stock plugs are fine until it misfires, then you replace them with a colder plug (NGK 97506).
