Spark plug gap?

[Cpt Marvel]

Sticker under hood says .040. Haynes manual says .048-.053. Autozone guy looked it up .035. WTF? If I don't get a response quick, going with the sticker

Sticker on mine says .040. So I gap my plugs at... .040 :icon_lol:

When in doubt, the under hood sticker has the final word. Actually, if you follow the sticker, there is no doubt!

Yeah. Thanks. Going with the sticker.

When playing the game of book-counter-sticker, the underhood sticker (that has info specific to your very vehicle) trumps the other two generic sources.
I thought that was already settled earlier? :shrug: :gr_grin:

Sticker is best specific reference as mentioned.
It also recommends the correct factory spark plug recommendation.

I change my plugs every 25k Miles, because the gaps are wider by then anyways.

Just an FYI, I was made aware to use only copper core plugs.. NGK R's is what I've used and haven't had a single hiccup... That is after I replaced all 6 coils and plugs together. I would stick with what is OE to the vehicle.
