    Work great on an F150 V8
    I bought these to replace the defective two piece OEM plugs that break off on my 2005 F150 V8. These are specifically designed to prevent breakage upon removal and can handle a lot of torque because they are a one piece design. The dealer wanted to install so called improved Motorcraft plugs and I said no way. Once the old plugs were out and these were in, the engine seemed to run a little better. Buy the way, the longer you wait to change the plugs, the more likely you will end up with serious engine damage.

    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.

    Very Good
    No issues with the delivery, the only 1 installation hint that I was told: I had to adjust the spark plugs to match 0.041" gap. The rest was obvious.
