IMO the plus 4's are totally pointless...
I'm running stock delco wires, cap and rotor with 99 cent delco plugs. I got 17.85 mpg on my last tank of gas, on a 10 year old truck with big ass tires and tall gears. And the plugs are a year and a half old.

I got mine at O'reilly's. I can't remember what the specific number was. I just told them I needed delco plugs for my truck, and thats what they give me. Remember to gap them correctly too.

I run Taylor wires on my trucks and NGK plugs in all my rides. NGK makes an excellent plug and has worked great for me. Oh yeah, I stick to the copper V-grooved plugs too, they are cheaper and work fine.
The Taylor wires are a nice piece specific to trucks also, fit nice and have been on for at least 20K mi.

I run MSD wires and delco plugs.....I dont know about gas mileage...
i currently have delco plugs and wires, but i just bought the accel tune up kit. instead of using the accel copper core plugs, i'm going w/ the delco platinum plugs.

Check air filter and fuel filter too. Also causes of mileage/power loss.
Personally, IMO, i like to put what was in there back in. If it came with platinums, put platinums, copper, put copper, etc. The NBS trucks came with iridiums in them. Not sure about OBS. However, you can run whatever you feel like. Copper don't have as long of a life as the plats and iridiums.
Also, if NBS, rememer to put antiseize compund on the threads of the plug (aluminum heads) so it doesn't get stuck in. OBS has iron heads and that is not necessary for them. Doesn't harmif you do either.

I am wondering then maybe someone can help me out. Those high performance plugs that are red, blue or yellow do they work about the same or better? I have a 8.1 Vortec and looking to tune mine up. I would also like to get an high performance distributor also.

Well typically they are supposed to have less resistance allowing for more spark or are just built better than OE. My Taylor wires were made for the truck specifically. I didn't notice any gains or losses from the Taylor ones...but at 50K that's a lil far for plug wires to me.
I thought the 8.1 was running coil packs (dizzy-less)?
AHHHH I seee 
.. I have about 47 and some change on my Truck and since I have big tires and take it off road. It's about time to give it some new plugs and other goddies. I have been reading about all the high proformance stuff on one of the magazines.. So I thought I would ask around and see what's out there... I have a K&N and Flow Master already. I wanted to make sure I get the most out of it. ow:

I get about 15.5mpg avg and just under 20mpg freeway in my Z...33" ATs, 3.73:1 gears, and driving about 70mph freeway. The key to fuel economy on being under geared is to drive in moderation...you have to cruise about, you have a nonaerodynamic brick.
Next, I stick with copper core plugs as they are less expensive than pts or iridiums...also copper works best with boost/nitrous.
As I said earlier, just plug wires and plugs aren't going to help so much as keeping up with reg. maintainence. FUEL FILTER is number one bitch that people forget. I change my every 10K.

Yep thats the one. I think the biggest part of it is the way i've been driving lately. There is nothing around here with a speed limit over 60, and no stop-go driving, and that really seems to conserve gas. On the way here driving through texas I worked really hard and kept it between 65-70 the whole way and got 15.9. If I keep it at 70-75, its like 13-14.DaHoe4x4Ag said:
