I bought NGK97506 spark plugs for my N20. I don't have a tool to set the gap, i was wondering what gap they come with standard. Can I just install them into the car? I am currently stg2 91oct.

The box doesnt say? Any autoparts store or amazon sells gap tools, just make sure you use the wire ones and not a feeler gauge or the round one that can damage the tip. You should always check before installing.

They should come @ 0.031" but it's suggested you measure to be sure. For the N20 you don't need to worry about changing the gap, many running factory gap @ stg 2 with no issues. Some have noticed that when they shorten the gap they have rough idling
