I have been using these plugs for years and green has always been the color of the stripes and the lettering on the Bosch plugs part# ZGR6STE2. I ordered a set of (6) on Amazon, made by Bosch, but shipped by Import Parts Depot. I received plugs with blue stripes and blue lettering. Not the same as the ones I pulled out. Should I install or return? Any input is appreciated.

Can you elaborate? ZGR6STE2 is stamped on the plug. Are you saying these aren't used anymore and there is a new Bosch plug part#?

I doubt there's is any difference. The spark plugs look indentical just make sure you gap them to the proper spec.

I hate to inform you, but these plugs do not need to be gapped. They are the stock plugs, not the NGK ones.

These are the same plugs I have in my tool box ready for install in the spring. I'd at least check the gap to make sure they match.

The greens ones aren't used anymore as it was replaced by the blue ones. Same goes for the ngk plugs.
