Stick with the OEM NGK, or Nippondenso plugs. Also, the plugs for the Platinum NGK's are about $12- $13 a plug, not $22, so you might want to look for a cheaper store to buy your NGK plugs.

 

You can either go with the stock NGK platinum or get the Denso Iridium plugs which are good but need to be changed every 30K miles.

 

Very good, thanks both very much!

 

Does anyone know if the Denso Iridiums (IK20) are pregapped?

 

Hey, I have Denso Iridiums and I believe it's supposed to last for 60K like the platinums. They came pregapped for most of the hondas and acura's according to the performance shop guy, and cost the same as the NGK's platinums about $13. Don't really feel much difference, but i'll most interested in seeing how durable these Iridiums hold up in the long run.
Only the actual copper plugs are the ones to be replaced every 30K, but it suppose to give better performance than platinum or iridium. That's the only tradeoff.

You should aways gap the plugs, or at least check the gap before you install new plugs even if they are so called pre gapped. Any slight hit on the box in the right place during packing or shipping could through the gap off. Not too mention you are betting that the comapany is gapping all the plugs they ship out correcly everytime. It takes all but 5 secons to at least check the gap.
