Great basic plug
The Autolite coppers aren't anything fancy. Just reliable workhorses that do well on the dyno and are easy to read.

Took a week to get them
Spark plugs were exactly as described and a great price. Don't know why it took so long to ship tho. Had 4 packs in stock, I ordered all 4 on Saturday. Showed next day delivery for 1, 3 days for 2 and 5 days for all 4 packs. There was no info on shipping until Wednesday and I received all 4 in one package on Friday. Overall very pleased with the product as usual but shipping time did leave room for improvement

Replacement for a champion RC12YC
I bought this for my Craftsman 10.5 HP Lawn tractor. The specified plug is a Champion RC12yc which costs significantly more. This plug is listed as an equivalent for the Champion and it works perfectly.

Basic and Inexpensive
I bought these because they are cheap Old School .... if you change your plugs yourself every 30,000 to 50,000 klms these are certainly the way to go .... if you pay someone $115.00 per hour to do it ... not so much buy the more expensive iridium or platinum tip ..
