Spark plug thread repair insert

These EMPI spark plug inserts require an M16 x 1.5 thread insert tool to fit, and are a quick solution to stripped spark plug threads.

Fits all air-cooled VW engines.

Simply cut a new thread and re-insert the spark plug with the insert attached and a little thread lock on the outer thread. Leave for a little while before starting the engine and your spark plugs will never fire out again.
