Do my plugs look okay?

 

You could probably use them again if you cleaned them up a bit. Try some JB Weld to repair the insulating collar around the (+) post. That'll stand up to higher temperature than silicone.

 

10 yr old acdelco plugs from a mercruiser
I wish there was a boat category. That's what I do all day

 

Chevy V6?

 

Mercury V8, usually around 300cu.in. is my guess

 

Hey @keep_hope_alive -- that car audio build log link in your sig, no workie

and its a mercruiser v8 (basically a chevy)

 

How did it run when they were in and how many miles?

Also my Accord has about 105,000 miles and still has the original plugs. How long have people been getting on plugs. It's the 2.4 on a 2014.

 

they are from a striper guide fishing boat. ran them for over 10 years

 

On my 97 S-10 the plugs in it were ran up to 149K when I changed them and the original plug wires. It came stock with AC Delco iridium plugs. Those are supposed to go 100K and then get changed. Those in my truck still looked good even at that mileage.
