plugs gapped to small

[talonkid93]

Couldnt find a link on this so im gonna ask. What will happen if your plugs are gapped to small? will it cause the car to not start or what....?

If the gap is much smaller than stock then your car will misfire and have preignition because, the plug will clear the gap because there is so little resistance, which is the gap. The car will start but not run a optimal performance.

Your going to foul out plugs from being gapped incorrectly. You will waste gas, and you will have some form of running problems. Go buy a decent set, check the gap and all will be good with the world. Dont let problems start on DSM's or thats all you will have.

Too small a gap yields a weak spark. Too wide a gap may keep the spark from even making the jump

Why do you ask? The main reason for closing the gap is to keep the spark from blowing out when running high boost. If the gap is too small the spark will be weak and likely won't ignite all the fuel in the cylinder.
