Yup, what 2002BLGT said. A gap as small as .035 is for when you're running nitrous..

0.045 gap is probably for carbureted cars.....because thats what I'm supposed to gap my plugs to.

If I remeber right .045 is also the gap for the plugs on my '93 4-popper. He may have just been looking at the wrong engine size on the screen. Make sure he didn't sell you the wrong plugs too. Should be autolite 25's
