Zman said: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.

if u got 17.85 mpg on that ride in your sig................damn that is awesome. im running stock size tires and can't get better than 15.1, and thats highway....maybe i should change my plugs and wires, they have never been changed as far as i knowWhifflebat said: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.
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:if u got 17.85 mpg on that ride in your sig................damn that is awesome. im running stock size tires and can't get better than 15.1, and thats highway....maybe i should change my plugs and wires, they have never been changed as far as i know
