I'd be inclined to use the O.E. plug. It's a relatively cold plug, which is proper for a s/c application. The NGK is a PFR7G11-S, or stock number 7772. Where are you located? These plugs retail at $29/ea. We sell them normally at $13 ea. I could get them at $9.90 ea. If you're close by, we could meet up and I'll hook you up. If you're in the Chicago area, I'll be at the unofficial meet tomorrow. Let me know soon if you want to do this!

Good luck! -Dave.

Farm and Fleet or any NGK dealer. DO NOT put any other plug other than than the OE, or the Iridium version.

Harry, if I'm not mistaken, Autozone just plugs in an OBD-II scanner to diagnose. I don't think they'll actually pull the plugs out and "read" them.

It's probably best to pull them and read them, as Harry suggested. It may be better to go with a colder plug, being that you're s/c. How many miles on them with the blower?

As long as you are using a "top of the line" item, both are worthy manufacturers. So, whether it's NKG or Denso is not material to the issue. The heat rating of the plug is material. You can read the plug and make a judgement as is mentioned in the post above.
Sorry I took for granted he was supercharged.

I said NGK, because after owning 5 Hondas, and seeing other Hondas, in NA engines NGK seems to be the least problematic and longest lasting plug for these engines.

Harry is right though you pick up the top grade, densos, or NGKs in the right heat range you will be golden.
