New Plugs - Worse Gas Mileage ???

[IRA51]

GLOW PLUGS ? You must be drinking too much Diesel . you should not expect the plug wires to last more than 3 or 4 years .plugs will last 70000 to 100000 miles and you should change the wires at each plug change .as they get older they get dryed out and are not as good wet as new ones and the resistance goes up putting strain on your coils as well. In Arizona the wires get dry and brittle in 2 or 3 years the high heat takes it's toll . if you want optimom preformance and fule milage and prefer not being stranded due to wet wires that cause a miss or won't even start change them at EVERY plug change. also you have a 50/50 chance that you will damage them changeing the plugs .they get stuck and you pull harder and you know what happens.spend mega bucks on a Hummer and cheap out on reuseing old wires I don't think so . Glow plugs indeed ,you must be on something bro. you don't know $hit from shineola. so when you shower you don't change your underwear too.
