First time changing plugs since taking ownership of the hundy a year ago, just wondering what u guys think of plugs... Originals, or estimated miles? Hope there not the originals as I just hit 200k miles... Pic:

I've read here, but can't guarantee, that original plugs have a letter embossed into the cap tip. My original plugs had "P" on their tips. I changed out at about 100k and didn't think/bother to confirm if the replacements had a letter on their tip. Your plugs look in good shape, seems 2UZs and Denso Iridium plugs are a good combination.

Those all look pretty clean - I'd guess less than 50K miles on them.

I didn't take photos of my old ones when I replaced at 100,000, but from memory, those look about like mine did. The engine is easy on plugs!

Those look so clean. I think they good for another 70k
Just a question . I heared you should not gap iridium plugs anymore! Is that right?

Last month replaced spark plugs (1st time) on 2003 LX 470 with 70k. Yours look similar to mine. I will check the "P" on cap tips.

NGK and Denso plugs are pre-gapped...but I still check just for S & G's. I've never found one with an incorrect gap.

Mine at 125k looked the same.

Well, before the spark plugs swap, there was a very slight hiccup between shifts at about 25 to 35 mph.. All that is gone... Same smooth performance just no hiccup..Swap was well worth it..
