Spark Gap how important

[G DANE]

I read in two different servicebulletins spark gap should be 0.9 mm or 0.8 mm.<br /><br />How important is the spark gap ? Which difference does it do. Does it affect spark plug temperature ?

Re: Spark Gap how important

It does effect the spark's temp.<br />Other reasons for getting the proper gap are;<br />Fouling. Too close and the byproducts will bridge the gap,and the plug is fouled.<br />Too far and the Cd unit will not be able to fully discharge,and will find another shortcut to arc-over...This could be in the plug wires, or worse, the unit itself or the coils to nearest ground. Which will ruin the said part (Coil/plug wire/switchbox ect).<br />I would go with the NEWEST service buliten's recommended gap.<br /><br />Hope this helps.
