Performance Tool W38170 Spark Socket Review

8 stubborn old spark plugs changed 100,000 miles with no problems. I had to take it off and put it back on every time, no problem. Can't beat the price

This is a great tool. It has thin walls so is well suited for cars like the Nissan GT-R or other cars with a narrow spark plug hole. It has a rubber grip inside but I wish it was magnetic but for the price it will work very well.

Just what I needed. Instead of a 'special' tool needed to change lower shifter cables on Mercruiser Alpha One output engines, this worked great! Simply use with a 5/8 deep jack on the back. The quality seems good enough for the price and I'm sure it will work well with any outlet of this size.

Poor quality. As another reviewer said, the piece of rubber that holds the spark plug doesn't stay on the socket. That was the case with my first spark plug change. Since the rubber piece remains on the spark plug, the rubber piece remains on the spark plug in your engine after the spark plug is installed. Maybe superglue is the answer, but I didn't have to do that for it to work.

I couldn't find a spark plug boot that size locally so I had to look online. I did, but the gum on the candle flew out. Glued super problem solved. Make sure the rubber element hasn't come loose before using it - my first spark plug stuck to the spark plug and I had to remove the spark plug to get the rubber element out. After I glued the rubber piece on, everything worked fine.
