On the subject of ?changing spark plug wires, I have to ask, why? I have read a lot of claims lately about the results from changing wires, running the gamut from 2mpg increase all the way to smoother shifting. If your engine is already running on all eight, and not throwing misfire codes, and providing a fat, blue spark, ?why would new plug wires make any difference? Ignition systems are usually hot-rodded ?because of running hard to ignite mixtures, high compression ratios, very high rpm and for supercharged applications. When going through an ignition system, spark plug wires are the end of the line, not the beginning. I'm sorry, but I have to question claims of four HP gains from replacing plug wires on a new vehicle.
So you are saying that all those that have done wires are all suffering the placebo effect ?
As far as "hits" go, the MSD/Wires thread is well over 6,000 ... That's an all time top 5 thread in this section ... Yep, we're either all looney or stupid for spending our dollars on such a fruitless mod ... ?
Trust me Steel, ?I have stated this before, as a matter of fact I think I stated it in the light of your skepticism ... They do make a difference ... Don't ask me why, but they do ... As a matter of fact, on my last 5.3's I never changed the wires ... As I was a skeptic too ... ?
There's an old phrase called, "don't knock it until ya try it..." ... I respect your background highly, and we are at odds in opinion sometimes... But I'm standing up on this one ...
I tell you what, you go any buy a set of Taylor TV-50's or MSD's and if you can HONESTLY tell me that you don't feel a difference in how the truck acts, I'll send you a $50 spot via paypal ... Now you have no reason to not try a set or refute our assertions... LOL ... BTW, I wasn't one that claimed better mileage, more HP, or smoother shifting ... ?
... All I said was a smoother powerband and increased response / less dead spot on bottom ... A truck doesn't have to make more HP to be faster ...
For the masses: ? Take 2 350 vettes, ?and run them side by side on the dyno one Tuned Port and one Carbureted ... They should be about the same on max HP ... Run them at the track with the same driver, and the carbureted vette will get beat by quite a margin ... ?The trap speeds will be very close, but the E.T. on the Tuned Port car will be less...
Now as far as the cold air kits, we'll always be at odds I think ... LOL ... ?

P.S. ... Since we're basing this whole thread on opinion and not fact... (of which I reference a lot ... fact) ... My buddy at the dealership here drove my truck last week after he centered my steering wheel on the rack, and commented on how gutsy my truck was from a stand still and on bottom end ... I think his words were, "it has no common hesitation or lag from the bottom when it starts out... Big difference from my avalanche, and the 5.3's I drive ... " ... Could it be the hpp3? or the cat back? ... Not in my opinion ... The magnaflow kit ADDED to the deadspot on bottom, the hypertech helped a little, and the wires did the most ... And it IS possible that the oem wires with 750+ ohms of resistance vs. the TV-50's with 50 Ohms may just increase the flame front propagation through a stronger flame kernel ... More voltage @ the gap means a quicker, more effecient burn ... Now Taylor has dyno sheets to back up the HP gains, are they real? maybe not, but they're the only ones who boast about it and they are a pretty long standing company who makes a good product ... Try a set Steel ... Quit being so stubborn ... Heck, I offered to even buy them for you ... LOL ... Aint I a nice guy ? ... 11H thinks Steel is missing out ... ?
