I have installed a new spark set plus4 for my Sephia 97. I took these plugs from a BMW 2002 car, one of my friends said that it will provide multiple spark paths and bring a powerfull spark.

Is that true? and does it cause any harm to the engine?

+4 is overkill and might make the car run a little crappy. i have bosch platinum+2.
also those pplugs off the bmw will not fit they are not the right part number. go to the parts store get them there.
