plug gap

[twozs]

no need for a heated debate , just some opinions on plug type and gap. first replacement since new(50,000)

If your running stock or close to, then i would stick with the stock gap of .60 and go with some NGK plugs. While your in there i would change out the wires.

Wider gaps provide a smoother idle and easier start up.....theoretically...that is why manufacturers call for them. Performance and MPG come from a smaller gap....and maybe a little rougher idle...so in between is the happy spot IMHO. Every new motor/car truck I get I always start out at the manufacturer recommended gap and work my way down until I find the happy spot. For the record on the GTO 408 Stroker I run NGK TR55's through MSD wires gapped at .040.....in the 5.3 2007 Silverado I run .050 NGK's .......

Yeah I'm doing a header swap next week so I went ahead and got some NGK TR55 plugs. After reading that link I think I'll go ahead w/ the MSD 8.5s.

Oh and where would you guys recommend purchasing the wires from? Do we have a sponsor on here who sells them?
