Review on 🔌 NGK G-Power ZFR5FGP Spark Plug by Mark Harris

Don't rely on the factory preset gap. I checked the gaps with a wire tool and three of the four required a slight adjustment from .045" or more to .044". Be sure to use a wire break tool, not a coin tool, as you can damage the delicate platinum tip of these spark plugs (see NGK's Spark Plug Gap YouTube video for more information). That being said, the spark plugs were easy to install and worked great (picture shows one new NGK spark plug on the left and four old ones on the right. They really needed to be replaced!)
