Side Gap Spark Plugs [*]

I was going to try it, then got lazy.

I think AR103s come side gap. I gap all my autolight plugs like that and never had any problems. When I had the 97 GTP I started doing it and noticed a 1 degree less KR so I never stopped. I don't notice any performance gains in the ol butt dyno or get any better fuel mileage so the benefits are minimal. I just look at it like its a step in putting new plugs in.
