Just a reminder for anyone changing their plugs in their pullied Cobra. Make sure and double check the gap, even when closing it, with fresh NGK TR6 plugs. I used a wire style tool when I first installed them, to what I thought was .035 gap. Got spark blowout when accelerating on the highway, so today I took out the plugs to re-gap them. This time I used a coin style tool. To my surprise, the plugs were at .050 gap, when I thought they were .035 via the wire gauge. Re-gapped the plugs to a snug .032 for peace of mind with the coin tool. Was quite surprised at the inaccuracy of the wire style tool.
