Plug gap is dependant on what kind of ignition system you are running.
And what type of load the engine will see. Power adders especially!!!:yes:

Is gap really anymore of a big deal than indexing? I figured all plugs were factory gapped nowadays, thats why they cost so damn much. Why else is a plug anymore than 50 cents?

If you're planning on spraying it, go ahead and tighten the gaps up to around .032"-to-.035" and get your tune dialed in.:yes: That way when you do want to squirt it you don't have to start over with your tune. :rolleyes:
