Ha, you caught me! Utilizing my “photographic memory,” I was installing plug #10 when I realized the Crossfire called for a plug gap of .39 NOT the .034 my faulty memory came up with. Wanting to justify not having to redo all the installed plugs I googled spark plug gapping and found enough information,(right or wrong) to justify leaving them at .034. Driving fast and furious for the last 2 weeks the performance is great. I haven’t a clue on the longevity of my mistake but i’m willing to risk it thinking I wont have the SRT for the next 13 years that the 1st set of plugs endured.
