What are the best spark plugs to fit to a 1.8 16v? I've got Bosch super +8 single points in atm. I did try some twin ngk plugs and it ran like shite! And they recommend not to touch the clearance on multi point plugs. Or can you? I did put in super 4s but got told they would burn a hole in my piston, which I thought was unlikely, but I still took em out lol
