hey people jsut bought a ngk spark plug . havnt put it in yet, but i will tomorrow. does anyone know how this helps and what it does. i also herd it that it genrates 5% more power..
cheers
I noticed that the NGK plug I bought was a different heat range so had a bigger insulator. I think I have heard that because the plug takes up more space you get a slightly better compression ratio and thats the improvement you see. I heard this in reference to irridium plugs too. But irriduims advantage is that they last heaps longer which dosent make much difference in an offroad, but in a 4cyl road bike where you have to take off fuel tank, air box, coil packs and then the plugs themselves are hard to get at and install then its is a BIG advantage.
