Does this look infected...

Change it. Corrosion on the threads and seat would bother me, looks like those plugs have been in there a long time!

Stick your thumb in the caps and crank it over make sure it’s getting good spark😂🤪

Pro tip: stick the plug in the front pocket of your jeans. Crank the bike, if you feel a little tickle the plug is good.

My guess is at least 126000 kms.
They're out of a 2012 Ford Fiesta... Car runs great, but I got to thinkin'... When was the last time the were plugs changed?
'Bought the car about 6-7 years ago for my youngest to drive back and forth to university.. It had 73000 km on it...
It's now just over 200000km.
'Kid got a new car when she graduated... We just kept this one and I drive it every day,
I hate it(too small) Lol, but it costs $400/yr. to insure and gets 6.3l/100km...

Installed the new plugs... I'll check 'em again in 125000km :)

In a modern fuel injected car, iridium plugs go 150k. The biggest easier is them sizing into heads from corrosion. 80k is good for a fi bike, never use them in a 2t bike.

Turbo cars are harder on plugs. The DISI 2.3T in my old CX-7 would eat a NGK Iridium within 100k. The ones in our Odyssey with it's NA motor have a recommended change interval of 160k per Honda and owners say even at that mileage they often come out looking great.
I run a NGK Iridium in my 300XC 2T without issues (only switched to it as all the KTM offroad guys recommended it as did the big offroad shops). I wouldn't have bothered changing to one but I was ordering parts from the US and needed to add a few $$ to get free shipping so ordered one. At 100hrs an Iridium plug is definitely ready for a change on this bike as it's pretty used up which is surprising.

My 2t bikes all call for iridium as standard? Why not use them?

Pulled the iridium plugs from my Echo at 197,000 KMS (or was it 297K???) . Looked fine and I would have reinstalled them but I had already purchased new ones.

What bikes do you have? Iridium plugs don’t like oil, they foul easily and once fouled they’re junk, I’ve never

They’ll work ok FI 2ts ridden hard, but overall not as well as a regular plug if you’re riding trails or under the power band.
