Yeah what everyone else said if you get the circualr type of gapper it is pretty self explanitory. On one side there is a measurement in thousands of an inch i.e. .035 on the other there is mm i.e. 1.0 which is equal to about .035 or .040 I'm not sure I'm going of the top of my head check to make sure though. Your factory gap and spark plug part # should be on the underside of your hood on the lil white tag there is also the valve lash setting for your intake and exhaust valves also.
