Review on NGK BP6HS Standard Spark Plug by Doug Olson

for my Coleman Powersports - CT100U Mini Bike, Hisun - 99cc / 3hp OHV engine to replace the horribly inferior Chinese spark plug "torch" that comes in the engine from the factory. I used a cheap Chinese spark plug during the 3 hour engine break-in period and replaced it when I drained the engine oil after engine break-in. The new NGK spark plug made my engine idle and ran much smoother than the crappy Torch brand spark plug and it was definitely worth switching to an NGK spark plug. I have trusted NGK sparks in all my 4x4s for over 20 years and will continue to use them. Simply put, NGK makes excellent quality spark plugs and in my personal opinion they are the best.
