what is the sparck gap for a 1986.5 nissan hardbody z24i d21?

Answer 1

That would depend on the plug and engine.

Answer 2

Go by the hood decal if it's there and legible. If not, you could go with whatever they are out of the box: with today's electronic ignition gap is not as critical as it used to be.

I go with a 35 thousandths gap when I can't find a gap spec, but I WILL NOT gap a plug to a point that the ground electrode is not at a 90 degree angle. Either pointing up or down from a 90 degree angle is a bad thing.

Answer 3

Most cars have a placard under the hood that should tell you the gap. This is however, the gap for the recommended stock spark plug for that particular engine, If you want to use aftermarket plugs, the gap might change.

Answer 4

If you look under the hood at those decals that tell you about the engine, somewhere on them is the plug gap setting. Have Fun!

if you get a good set of the boch plugs they are mostly pregapped, but if you need to know, look on the front portion under the hood, for a tag that has some engin specifications, the spark plug gap should be one of them.
