Spark plug effect on cng pick?

Assalam-o-alaykum!
I need to confirm that whether spark plug quality effects the pick in cng or not. Some say yes other say no , it only makes difference in petrol. Some mechanics told me that only the gap of spark effects the pick in cng. Anyone who has tried high qulaity spark plugs and found major difference, please tell me. I have a 96 margalla.

Wslm!
yes, spark plugs have effect on cng.the plug's tips should be cleaned with a sand paper to remove residual carbon.in single tip sprk plug,gap is decreased to give a better explosion. as gas air mixture is less dense as compared 2 petrol air mix, so gap is decreased. i have 4 tip plugs in my alto. multi tip plugs r not useful 4 carbi engines. so stick with the single tip or almost 2 tip denso.
