Iridium spark plug

I want to use an iridium spark plug in my 2001 model 1.6 8v petrol lpg vehicle What's the pros and cons? I'm waiting for comments from friends who wear it

Iridium spark plug will need more energy than the spark plugs used in your vehicle. I do not know the numerical net, but the coil will not be enough to feed the iridium spark plugs. If it is necessary to switch to iridium, the ignition system should be modified according to these spark plugs.

I consulted Atiker dealer and service, the answer is the same original spark plug
