spark plugs

what are the best spark plugs? they are for an 88 s-10 4.3. i want better gas milage. it has a miss if ya get on it to hard. had the bosh platium 2s. yeah i know its not spelled right im in a hurry. give me options.

gm = ac delco! anything else is a waste of time.just put what is supposed to be in it and elimate the plugs as the problem.

i recently threw a set of those e3's in my neighbor's typhoon 4.3 & that smoothed out his SLIGHT miss & got a noticeable mpg difference he said, but nothing to REALLY brag about. i could ask him, but i think it was like 2 or 3 mpg he was saying.

I back this 100%

cool im headed tomorrow to get them. i did put a throttle body spacer on it and an cold air intake. the intake is 14 inch and i know normal its 10. will this help or hurt my mpg?

got ac delco rapidfires

i wouldnt have got the rapid fires i would have went with the plain old delco's i work for an auto parts store and have an 89 s10 4.3 and jumped up to the 14 in breather and didnt notice any milage but a shit load of power how close is that to hitting your hood because i dont have a spacer on mine and its like 1/2 in from the hood

i actually just hits the hood. it makes an imprint in the fabric on the hood. i had to trim the throttle body screw so it would fit. i seen 2mpg better but i used a k and n fliter as well. have you tryed to underdrive pulls? im trying to squeeze all i can out of it. the spacer made more midrange torque. i believe mine has a high rise intake on it anyways.
