Same as what local stores around here sell, but at third the price.

Good plug

Also gap them at 25 mils that helps greatly to reduce blowby, in particular with a turbo charged engine. Do have 50K miles on my old ones, twice around the world, time to replace them. I want to burn my fuel inside of the combustion chamber and not within the confines of the catalytic converter.
Just an old retired electronic engineer that has been designing ignition systems for the last 40 years.
