If I were to replace my plugs, what should I go with? NGK's or Denso's? (iridiums of some sort).

I think the reason the Denso and NGK iridiums are more expensive, is because they are "long life" plugs. They are supposed to last 100k miles. My 03 V6 came with the long life iridium Denso plugs, and the engine is still running as smooth as ever at 67k miles, with those original plugs. I took a couple of them out, just to check their condition, and they look fine. I keep thinking about changing them before 100k miles, but haven't done it yet. I don't think the platinum plugs are 100k mile plugs, so while they may cost less, you will be changing them more often.

i just need to pull mine out, check them, make sure the previous owner didn't put some goofy plug in the car ya know. Like diamond fire, or Split fire. I want OEM plugs.

NGK works fine with me no problem.

I've always been a NGK kind of dude. Denso works too, but just never ran them for no apparent reason. I wonder what Honda put in from the factory... denso or ngk.

My 03 V6 had the Denso's as original plugs. They are still in there, at 67k miles.

i have used denso iridium plugs alot in my Honda's i like them never used ngk

ok, so looks like Denso was probably the OEM supplier.

I'm pretty sure they still use both NGK and Denso. I know they've used both Denso and Delphi alternators, so parts are not all exclusive to one manufacturer.

ok. so which ever one I can get easier/cheaper if the plugs need changed. Hopefully they don't need it, and the previous owner resisted his urges to put in spark plugs that he saw on a info-mercial.
