Hi guys, i brought the wrong NGK Iridium spark plug model for my Honda civic EK SiR B-series model.

Will i damage the engine or cause any problems to it?
After i had changed, i kinda smell some sort of buring smell inside my car.
I'm quite worried is it the cause of wrong model of spark plug i brought?

I brought ZFR6FIX-11 instead of BKR6E-N-11..
