Any plug with built in resistor should do just fine according to this. feel free to correct me on this.
True. Do you have an integral resistor plug?
NGKs Its what Honda recommends why fight it? Honda designed the engine. Use the part finder

Honda uses platinum plugs in the new cars with coil pack system and standard plugs in the single coil distributor systems. It is easier to fire a standard plug as apposed to a platinum plug (platinum plugs use a small tip and platinum have more resistants).
http://www.ngksparkplugs.com/product...r.asp?mode=nml " Lowers ignition system voltage requirements" standard plug. Coil pack systems have more time to recharge the coils because thy have so many (one per plug) you only have one coil that is now working over time to fire the platinum plugs (this is only at higher rpms) this may be why you coil died (only a theory).
Think about it on a coil on plug system at 5000 rpms the individual coil only has to fire 2500 times. On a distributor system at 5000 rpms your single coil has to fire 10000 times. Their is a power stroke every 180 degrees on the crank.
I personally have ran into misfire codes with the use of bosh platinums in a engine that desired the use of standard plugs. But hay its not like thy miss all the time its your car. Misfires only effects gas mileage and power it will not damage your engine it can however damage you cat because all the extra HC's (this will take a lot of time). I would at least switch to a normal plug. Just try a set of NGKs for a bit if you do not like them switch back. NGKs speak for them selves.
I will agree platinums sound better due to long life and thy are harder to foul out thy are a better designed plug. Used in the proper ignition system platinums are great. On some Honda's thy do not recommend a change of plugs for 105 k. Thy are used in the new J and K series engine.
I also found this
http://www.ngksparkplugs.com/tech_su...d.asp?mode=nml pull a plug see how it looks maybe even take a pick to help us put the platinum question to rest. I would like to know if I'm wrong or rite if you don't mind ether way you question will be answered by you. I'm guessing you will find your plugs wet or dry fouled.
