I just bought a set of 6 NGK Laser Platinum spark plugs. They came in a Nissan Box. my question is, are these pre-gapped for maximas or should i gap it to .044? and if so, how do you Gap these things? i have no idea. Thanks.

 

Yep, they're pre-gapped.

If you want to check for sure, go to any Auto Parts store and ask for a gapping tool.

They usually cost aobut $1.00
