what exactly is that Torque? for a 2000 Silverado Z71? That makes sense though what you said, I never thought of it that way.
And OP here are my Plug Specs...
I Heard NGK made the ACDelco plugs, so I just recently installed NGK Laser Double Platinums #3784 for my 2000 Silverado 1500 LS Z71 5.3L and got MSD 8.5mm Super Conductors #32829 for the wires. They work Great! Definitely more power, much cleaner idle, actually it added enough extra power from before that I blew part of my exhaust bracket from the pipes, and wore out my tensioners! Granted i'm sure all of these were on the way out, but it wasn't until I changed my plugs and wires to these that all these New Noises started. Also I don't know how old the plugs and wires were, but they were ACDelco Plugs and Autolites 7mm Wires and the plugs did not have bad damage or anything on them, so i'm sure they couldn't have been that old.
I Agree ACDelco is the best for most, but I mean you all have to admit there are definitely certain brands that make better products than ACDelco. They specialize in certain manufacturing while ACDelco makes Every Single Individual Part for Every Single GM Vehicle.
A neighbor mechanic said that I should use the ACDelco oil filter because it uses some "special" oil back flow thing I don't know, but like that (and i'm going to try it out next oil change to see) but come on you're telling me ACDelco Oil Filters are better than Mobil 1 the Leading Brand in Oil?!
