Has anyone tried the Champion double platinum spark plugs? I bought them yesterday but haven't put them in yet ('98 5.9L). I was trying to find the actual Champion Truck Plug, but no one carries it in stock. I am debating just putting the doubles in or returning them and just getting truck plugs (they are cheaper anyway).

 

i just put them in mine about 800 miles ago. my parts store also only had them in stock. i think they do it just to make you spend more. but i think they work fine cant really tell a diff anyway
