Water damaged, letters faded and dirty.
Boxes look damaged. They also look like they have been drenched in water. The spark plug brand is also very faded. They are also kind of dirty. Not sure if they are real will definitely be returning them.

This is the plug for a Sears garden tiller.
I got the number off the old plug and ordered the same from Amazon. Tiller is working fine.

Did what it needs to do.
Haven't tried it on long run but it always give me a one click start even on cold winter weather. Idling is better than ngk plugs. Still need to wait for good weather to test it on long runs.
