Spark plug ?'s
 

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). :confused:

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!

I used iridiums in my non-S boxster for about 2 months and they were ok, i changed them to a copper type bosch plug and the idle and acceration are smoother and more consistent than the iridium.... plus i have peice of mind that the electrode wont break off and damage my cyclindar walls or valves.

Just sell the old plugs on eBay and buy the OEM ones from www.************************************************************ , good luck!

Go stock..."Upgrading" to a different type of plug can/will affect the car. The Boxster seems very sensitive to non OEM parts. Sometimes its best to stick with what you know works! :cheers:

Thanks guys, will go stock. Silly me trying to get a lil performance from a plug :o
