Review on NGK Resistor Sparkplug DR8ES L 1993 2005 by Abdur Fulton

I bought a sparkplug for my motorcycle hoping to improve performance .Unfortunately, it ended up causing more harm than good. After installing it, my engine started to misfire and i had trouble accelerating. It turns out this product doesn't work well with certain automotive models. The only good thing is that it was cheap, but that doesn`t make up for the damage it caused..
