The repair manual gives the size of gap for Champion spark plugs. I looked on the internet, it doesn't give the gap for Bosch spark plugs, but says they come with the gap already set. It seems strange to me to buy and use spark plugs without knowing and confirming the size of the gap. Any opinions?
