I think you will get better gas mileage on the iridiums, personal opinion. I melt iridium plugs though... : (

thats nice, i guess they do last for inexpensive plugs

any idea were the plugs are on the GXP? lol
cant find em

the GXP has what are known as C.O.P.* coil on plugs take the beauty cover off and you should see them on top of the heads. if i had a GXP near by i'd get ya a pic of them

i think i saw them but i wasnt sure if its the one

ill snap a picture tomorrow and post it


oh sorry for hijacking the thread :P

HEY! autolites on sale lol

not a hijack we were still talking about autolite spark plugs

I bought (24) 103'* and (24) 104'*. I'll have them at both Dan'* meet and mine and Trent'* meet. I'll sell them for $8 per set of six if anyone wants to swap their spark plugs.

It would normally cost you $7.50 + 7 shipping. This will be a good deal while supplies last :P.

I'll either take 6 or 12 plugs. I change mine once a year in spring.
