Heza Posted November 9, 2004 Report Share Posted November 9, 2004 so...today i went to my favoritist parts counter to get my replacement platinum Delco plugs recommended for my motor and i came out surprised. did anyone else know that AC Delco changed the part number and now give Iridium plugs in place of the platinums? i didnt, so now have Delco iridiums to install. also...when i pulled just one of my old plugs, i noticed the gap on it was .65 inches instead of .45. would this be where my shitty mileage was coming from? just curious...

93CutlassSupreme Posted November 10, 2004 Report Share Posted November 10, 2004 could be, but don't expect a big gas mileage increase all my plugs were way overgapped (which is why i believe platnum plugs are a waste of money) and my mileage didn't change when i put new plugs in. i still get shitty milage Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted November 10, 2004 Report Share Posted November 10, 2004 yeah, you might notice a little more MPG, but if you had any trouble getting the car start, that'll prolly go away with new plugs Quote Link to comment Share on other sites More sharing options...
joey b Posted November 17, 2004 Report Share Posted November 17, 2004 96/97 calls for a .060 gap. All of mine are at .045 and I like the outcome vs. .060. Quote Link to comment Share on other sites More sharing options...
