Birthday cake candles?
How come spark plug sockets are a weird size anyway? One I have says 16mm on the side but it's actually more like 21mm. Are Spark Plugs measured differently?
EDIT - Just read its the size across the threads that gives its size, so a 16mm spark plug is 16mm across the threads, nothing to do with the nut size
