Seem to Be Very Very Good
Spark plugs working very well day of installation. The biggest bonus is these spark plugs have no ribs. This makes pulling the coil boot off the spark plug that much easier after 100,000 miles. The Nissan motor i replaced the plugs on has a tension bolt to keep the coil on the spark plug so the danger of it popping off is gone. Apart from some minor heat dissipation benefits there are no need for ribs. (The picture online and on the box is misleading, as champion used a generic plug of theirs for the photo, and it has ribs). On my original OEM spark plugs the rubber boots stayed on the plugs when I pulled out the coil boot, partly due to the ribbing on plugs. I had to dig them out with a pic and vacuum. That took several hours. I also added dialectric grease to where rubber boot meets plug which will help too.
