  • Q:

    While searching for spark plugs that fit my vehicle on this website, i've ran across a problem. the owners manual for my truck and the sticker under the hood all says to gap new plugs to .35. well while searching on all the plugs that fit my vehicle. well all the other brands popped up on their page on this website that said to gap at .35. NGK,AC, autolite, etc. all on this website said to gap and .35. however, when i came to the denso plug that fits my vehicle, it said on it's page on your website to gap at .40. so i did another search for another vehicle i own. manual and sticker on it said to gap at .60. well, again i do a search, and all the brands again, NGK, AC, AUTOLITE, etc. all said to gap at .60. However, the two denso's that popped up that would fit it, both had different gap numbers. the one denso said .44 and the other said .50. So when i buy denso and gap them, what do i do? gap them by the manual and sticker says to gap them, or by what this website says to gap them?
