Nice. Glad NGK makes it so straight forward. :lol:

It actually got me, and I am a dealer tech. Looked up the plugs for my car and Honda only lists Denso. No way I would use Denso plugs, have seen FAR too many blow out of the heads, and have never seen an NGK plug do that, so had to look up the right number on the NGK site. First time, ordered just the Iridium, noticed my mistake later, then ordered the proper "platinum".

Four (including shipping) was less than the price of two locally, and was about $2.00 more than the cheaper Bosch's that were available locally.
Now awaiting arrival.


Good choice. Should only use NGK in a Honda. Which version did you get? NGK lists "Iridium" and "Platinum" for the car, the "Platinum" are actually the correct plug, they are actually Iridium with a platinum ground electrode instead of a copper ground. The OE plugs are the "Platinum" version and will easily last twice as long as the "Iridium" version.



You got me thinking and I went back and checked. It said they were OE, but I hope I got the right ones:

Also, are these pre-gapped, or do I need to gap them. Thanks.

Checked that number at NGK. Those are the Iridium with Platinum ground electrode. Those are the correct ones. The -11 at the end means they are pregappged to 1.1mm, which is good because platinum ground electrode plugs can not be gapped.
