Re: Iridium spark plugs anyone use
Well I put in the new plugs and took my first 2 hour trip on the highway to a swap meet. The truck ran great funny thing is with new plugs truck seemed to run a little richer. With old plugs air/fuel stayed about 13.5-14 and iridium plugs are running 13. At idle the new plugs are even hitting 12 so interested to see what happens when these get a little age on them. I thought new plugs helped with better starts but after walking around swap meet and trying to start truck I had some starting issue. So far new plugs act like old plugs .
