Reading My Spark Plugs (1 Viewer)

Hello All,

I just removed these spark plugs. They have at least 45k miles on them. Do they look okay? Plug 1 is at the bottom and plug 6 is up top. Thanks!

IMO, looking good!

That's what I thought. Absent any symptoms not described; good to go.
I notice a fancy thin electrode. I'll surely be taken to the back of the MUD woodshed for this, but I just go with the OEM normal plugs. They are so reasonably priced that I almost fainted when I got my first half dozen.

They look good. Nice even light brown color.
No fuel or oil issues.

Double check the gap and install them.

Thank you all!

The plugs look extremely good, as already mentioned you could carefully clean and regap those (that's what we all used to do) and run them another 50,000 miles but then, IMHO, the crush washer/gasket should probably be replaced (most people don't and have no issues), so that's a hassle trying to find the correct crush washer/gasket, ---

Either way, while they're out it would be easier to just buy another set of the same plugs which appear to be NGK Iridium plugs (BKR5EIX).





@Tachycardic : personally I would not go to a standard plug; the Iridium plugs IME work very well (?better than standard) and can be run up to 100,000 miles.

IME DENSO IRIDIUM Power or DENSO IRIDIUM TT spark plugs are excellent long lasting spark plugs also, likely similar performance as
the NGK Iridiums but I haven't used that brand of Iridium plugs myself.
