lxman-How did you go about with a .044 gap on the ngks. The manual calls for a .035 gap. I finally got aroung to swapin my 03's 5.7 at 28k miles ( yea only 28k in 5 years). I did a .040 gap on them and also swaped the wires with shorty wires. Will the .009 or .005 diffarence from the manual sugjestion gap affect the hemi in any way?
And for those of you whom did the shorty wire swap , did you notice a change in exaust tone?

Not sure where .044 came from. Probably NGK website.
