spark plug gaps

I know my plugs need to be gapped at 0.045, but what units is that in? Because I can only find gappers in the ball park of 0.45mm, is that the same thing? Thanks.

That's inches... 0.045 inches...

You could probably get a wire-type gapper out of JC Whitney, or Summit Racing, or a similar mail-order place, if Canada doesn't have any.

[edit] Now that I think about it, Summit doesn't have the swing-out wire-gauge gapper. They have a sweet (but Xpensive) pliers-type gapper; very accurate, but the $5 wire-gauge one works just as well. Whitney's probably has it.

Matlock,

1.1mm is pretty damn close to 0.045" - close enough for a few thousand volts, anyway....

You can use feeler gauges if you have them to set gap.

Hate to say it, but most are pre gapped ... or so they say. I bought a set and turns out 3 out of the 8 were way off. Need to check anyway.
