Re: What spark plugs are best?
Im not usually one to expect gains from little things from plugs, leads filters etc, however I had an interesting result with my last change.
I had 15,00km old NGK-R plugs. I changed them with a set of Bosc Super 4 Plugs (got them for the same price as the NGK's), EL leads and my car picked up 3MPH down the 1/4 consistently. It was the only change since the last time I raced the car.
Besides that, i just noticed the cars a little smoother on start up.
I might give those mock plugs a go one day.
CAUTION: Slippery When BOOSTING!
