Re: New Plugs - Worse Gas Mileage ???
If You want to change wires go to Taylor wires and You should not ever have to change them again. Nothing against MSD as i like there products. MSD hired HPTUNERS.com to do the programs for MSD Superchips programmer and HPTUNERS.com assist the Superchips racing team with there specialty tuning so that tells me MSD wants to do things right.
Due to old school I ran all Accel ignition parts back in the 70's on my 68 Mustang Coupe with 289 high perf. twin 700 Holy double pumpers on a tunnel ram. Accel was just real popular at that time and they functioned to perfection for me.
Go to most performance shops and they will recommend Taylor wires especially in the southern USA. Taylor is highly thought of in pro drag racing. I have a set on a 99 Silverado that has everything done to it to make it run except no forced induction and I have a set of Taylors that are 7 years old used under extreme load and extreme heat situations daily and still read the same with a meter as when they were new.
I changed to Taylor wires on H2 as soon as i bought my first handheld programmer knowing I was going to get better spark and next I will change to MSD coil pacs on H2.
