Anybody ever use Denso spark plugs? I had AC Delco in my 91 Vette and somewhere along the line at a mechanics shop, they swapped them out with Denso K16PR-U11. I didn't know that they even did it. Mechanic never told me. Never even heard of them before.

Yes, they are good plugs, used them a couple times, just put Platinums in my LT1 not long ago. IDK about the specific # you listed though.

I checked the number on the Denso plugs and they are not for that engine. Too short. Thanks for the reply.
