spark plug fire test...how to?

[howiechoo]

got a question, how we can know whether our spark plug had better ignition after we add on something like better ignition coil / spark booster?

i saw in carrefour there's a small device to let customer to see how the spark like after add the extra things...so how we goonna test it in car? can we just take out 1 spark plug and see how it fire?

maybe a bit silly but i think this is the best way to prove whether the booster things we added are useful or not...

yes, place it on top cover of engine to see firing sparks, but before that please make sure no oil leakage or oil wets on top heads or manifold section. This is to prevent spark plug firing to accidently catch fire in any situation.

Thnx
