What happens if spark plug gap is too big?

What does a smaller spark plug gap do?
A smaller gap ensures the spark plug fires on each cycle. But if the spark gap is too small, there won't be enough room for the airfuel mixture between the ground electrode and center electrode. So when the spark plug fires, there's a possibility that nothing ignites.22-Dec-2021
Is a bigger spark plug gap better?
The larger the gap, the more voltage is needed to jump the gap. Most experienced tuners know that increasing the gap size increases the spark area exposed to the air-fuel mixture, which maximizes burn efficiency.

Is Champion qc12yc the same as RC12YC?
Premium Member. From what I can find the two plugs have the same heat range so are interchangeable without any difference in mechanical engine performance. BUT if you have a fuel injected engine you should use the QC plug. It's internal electrical construction is different to work properly with fuel injection systems.06-May-2018
