ok, decided that maybe some of my engine fual cut offs at high rpms was MAYBE the plugs, so I went to buy some NGK ZFR6J-11 plugs, one step colder, but advanced automotive said they are discontinued, so I bought a plug that was eqivalant, an autolite brand. I put it on my gapping tool, it it's gapped at .40 right now, do I just set it on the .30 and bend the thing down so that it's at .30? is that how you gap spark plugs?

 

 

smack it against something flat...
