Pretty sure that's what is i the TSX from the factory, adn they're good for a LONG LONG time. Why waste the money by replacing w/ the same thing, well before their useful life is even up?

Here's a quote from a knowledgeable source:

So changing out the stock iridiums with new iridiums, IMO, is a complete waste of cash unless your current spark plugs are in horrible shape (but then you have other issues to deal with methinks!).

They are basically the top of the range of street plugs. Any higher and you are looking at multiple prong plugs or the ones with extra thin electrodes (which last only about 45-50k). The extra thin ones are 0.6mm for NGK (Iridium IX) and 0.4mm for Denso (Iridium Power). If you are going for normal iridiums, both brands are similar. However, the Denso Iridium Power should give a better spark as it requires less voltage but they have a shorter lifespan.

I felt like tinkering and replaced the stock plugs with Denso Iridium Power IK20s. I also had some knocking on a couple of occasions and thought that the stock plugs might be a little hot.
The Densos felt a little smoother than the originals when they were first installed, but that may be because they were new and pristine with absolutely no fouling. I haven't had any knocking, but that may be coincidental (the original problem may have been bad gas).
I now have about 15k on them, and I have had absolutely no problems.
If you're bored and feel like tinkering, this is a relatively inexpensive experiment; it's an easy swap-out, and there's no downside (even if they do wear out quicker, you can always put the originals back in). But there's nothing wrong with the stock plugs, and you may want to save the money for something else.
