Review on Hazet Spark Socket Drive HZ880AMGT 1 by Jason Tinnen

I bought this tool to change the spark plugs in my 1988 BMW M3. The s14 engine in these cars has very thin spark plug walls, requiring any other spark plug socket to be ground to match. It doesn't need any sanding at all and comes with a magnet so you don't have to worry about the spark plug getting into the engine. This is perfect for E30 M3 S14 engines and M5/M6 S38 engines.
