If I'm not mistaken, it should be set at .041 with NGK spark plugs

Check the owners manual... it's in the Maintenance section.. on my car it's .043 but I have a 99... it's in your owners manual

My owner's manual ('98) gives a range for the gap, not a specific number. So you MIGHT run into that, too.

CALI--Sorry, I've been gone all weekend. I'll get that range to you tonight, straight from the owners manual. :smile:

Ok, here it is, straight from the 1998 owners manual:

0.039-0.043

You can experiment and leave it at whatever feels best or when you're sick of pulling spark plugs... :biggrin:

BTW, the Haynes Repair manual gives the same range. I think I set mine for 0.043.

From what I've heard from some top mechanics if you have NGK spark plugs they come gapped already so you dont have to worry about gapping them, because I just changed mine and I bought NGK and I dident need to gap them.

Yes, they do come gapped. But they always recommend that you check the gap prior to installation.
