im in need of some new spark plugs for my 02 tl-s. ive searched and found mixed info regarding ngk ik16's vs. ik20's (i think those are the part #'s). well i have intake, headers, and some other mods. Would it be better to go with the colder ik20's or no?
also what were the part #s for the denso iridiums? thanks guys!

IK16 and IK20 are Denso part numbers. Stock is the IK16, and the IK20 is the colder plug.
For NGK part numbers, the part # is ZFR5FIX-11 (TL-S application) or BKR6EIX-11 (NSX application/colder plug). I think the 4th digit is the heat range.
I'm running ZFR5FIX-11. I think either plug would be fine - even on a TL-S with mods.

The part numbers are in the owners manual.
NGK's are installed at the factory and the P/N on my 2002 TL type S are PZFR6E-11. These are platinum tipped. The Iridiums have a 6 in the p/n as well (I believe I got that from the NGK site)
I dont know what these other p/n's you speak of are, probably the iridiums but for the -p's. There is a difference between tl-p and -s, but have heard of folks using either-or and being ok. The difference in the plugs is a difference in heat dissipation. Reach, thread, etc are the same.
I've got pics of my plug change but have been too la - I mean busy - to post them.

That was still cheaper than the platinum NGK's.

Ok - end all.
According to page 242 of the TL owners manual:
Premium Model
NGK: PZFR5F-11
DENSO: PKJ16CR-L11
spark plug gap: .04 in (1.1mm)
Type S
NGK: PZFR6E-11
DENSO: PKJ20CR-M11
spark plug gap 0.04in (1.1mm)
I know the PZFR6E-11 is a "cool" plug since it dissipates heat to the head more so than the PZFR5F-11. PZFR6E-11 were installed on my TL-s at the factory. No mods.
I think you can use both plugs and be just fine. They cost about the same anyway. You might have a better time finding the '5F-11's in stock at autostores since I think they are used in other Honda V6 engines (not sure tho).

Awesome SPL1011, and thanks. Someone actually went to the manual! DoH I wish I had thought of that!
Now, to throw a monkey wrench here, is the
NGK PZFR5F-11 the same as the NGK ZFR5FIX-11?? Aside from a "P" in front of the OEM listing, and a "IX" at the end of the other NGK part number, does anyone know if these are the same?

Which is preferred, the platinum or iridium, and why?

Well, I had 68k on my stock platinums when I changed them they looked really good. Clean, no pitting or noticeable electrode wear. Gaps were still a tight .040".
Iridiums are supposed to have better resistance to wear (4 times harder than platinum). They also tend to cost more. Don't look for a power improvement between NGK plats' or iridiums - you wont find one.
I guess it comes down to personal preference. For me, there was no value added and the money I saved paid for the anti-sieze stuff. I stuck with platinums. In my professional opinion, there really is no difference in our cars.
