Odd plugs

[paulo57509]

They're fake, according to the .pdf file above. Why? The ground electrode has a "pin" sticking out toward the center electrode.

I think the plugs in the Post #1 are real.

The plugs in the original post are IK20L (ground electrode is Nickel U-Groove). The plugs you're referring to (wlk's replacements?) are IK20TT (ground electrode is Platinum fine wire).

Denso states 30k mile longevity for the former, 100k miles for the latter.

I wonder if they were double iridium in the first place. Are the new plugs the same part number?

No I switched to Denso Twin Tips for the new ones

Here is a shot of the old ones new at RA listing. I thought they were 100k plugs as it says in info. Good to know they are only 30k's then. I like and used the TT's in other vehicles and hopefully good for another 50k.
