Talking Re: New Plugs - Worse Gas Mileage ???

Bosch plugs blow,use NGK or AC Delco. and always change the spark plug wires at EVERY plug change . also change the plugs with a cold engine never remove a plug from a hot or warm engine with aluminum heads and also use anti seize compound on the plugs and dielitric grease in the wires and any eletric conection under the hood . you may have f*cked up a plug wire when you removed it .check the summit or jegs catologe for some MSD 8.5 mm wires they do a nice job and have a very low resistance and are priced less than what the dealer has .
