so how does this spark plug look ?

[WildHorse]

30000 miles on it. All look exactly alike. No wetness, nice clean burn, in my opinion. Replacing them with the OEM NGK's.

Clean, electrode in good shape, no deposits.....made in the wrong country.

Plenty of life left on it, how many miles on it ?

Looks fine, are you having issues with spark or are you just doing a routine maintenance on it?

As I stated, 30000. Wrong country maybe, but those are original motorcrafts aka NGK.

Just routine maintenance. Figured with 30000 miles on them I'll give em an early retirement while they're still healthy haha.

While the NGKs offers 1/2 heat range increments, I prefer the Autolites. Fuel injection, on the fly timing, and the ignitions of today allow plugs to go the distance, 50 -75 k. I as you will change the plugs at 30k..

Had a 'FACEBOOK tuner' on one of them pages tell me I coulda went another 30K on em and I wasted 80 bucks. Right, 80 bucks every 30k is a total waste of money haha.

Looks fine to me!

The top of the plug looks perfectly fine indeed. But why all that rust on the threads? I don't like that. Is that normal? Hey OP, did you have a hard time getting them out? And do you live near the ocean, to justify all that rust? Just curious. Some anti-seize paste might help in your case.

The only ocean around here are miles and miles of flat prairie haha. Rust.. dunno, I'm assuming the steel inserts in the heads. Getting em out was a piece of cake. Took like 20 mins. I never use anti seize. These are after seated 1/16 of a turn or 22.5°.

Better Japan than Chiinaa...

Yep. The fake NGK's are from China.. pretty convincing at first glance too.

Never use anti-seize on spark plugs. This affects the torque value when you are tightening them and will lead to your spark plugs being overtightened. May not be the end of the world but you would hate to over-torque and snap a plug. I was watching a video of It'sJustA6 and they put anti-seize on his spark plugs for his camaro that just got procharged. Really pissed me off, lol. I know in the NGK instructions it specifically says not to use anti-seize.

The plugs just need to seal, they are not going to shake loose or back out. Did you index them, we could pick at this all day .

How do you index them with the head on ? Also, chances are at least a few cylinders will need washers for proper indexing, which is moot with a tapered seat. I got time today. Haha.

Thats normal, I think its the nickel coating changing color as it ages with heat cycles.
