I just purchase a complete set of Denso Iridium Power spark plugs (IK20 5304) for my Boxster S. Doing some research on spark plugs I became kinda worried when when I found out that some spark plugs melt do to the power and heat generated by the engine. These plugs have a 5K Monolithic Resistor but Porsche recommends 7k or so with their (FRG6KQC).

Kinda confused and worried now since I already purchase these plugs, wondering if anyone has any advise or has used these plugs on their Porchse without any problems?

Thanks!
