Bosch spark plugs.
Anyone using these new platinum spark plugs, have 4 points that throw the spark on them? Bought em at a parts store for my truck yesterday, and think I may actually be able to tell a difference. Could be the new KN air filter too, but I think between these 2 things, I can actually feel it when I press on the gas pedal. No need to gap em. Gotta get some for the bike and see. Tried the splitfires a while ago, and wasn't impressed. They were fine and all, just didn't notice any improvement for the extra $. We'll see how these go if I can get em for the bike.

not in any way at all would i fall for a gimmick like the newest spark plug that has several ground pins. all i use is the harley gold spark plugs, and haven't had any issues at all. you may be feeling the difference in the way your truck runs because it may have needed new plugs and an air filter. sometimes in order to justify an expense, they "feel" like it runs better. electricity follows the path of least resistance, no matter if it's got 1,2,3,or four ground legs.

Haven't tried these, probably won't for the price. Having lived in Ohio for many years and knowing many people that have worked for Champion and AutoLite, the one thing I believe is them when they tell me plugs like this are developed for one reason, our human desire to find something better. Because of this we will believe it works better and we can "feel" the difference. Yeah, right! My neighbor worked in Fostoria at the test lab and when they tried all different plug considerations there was no improvement in combustion from any single plug head, even with the different electrode setups. The only way they obtained better combustion was to add a plug to the combustion chamber, a dual plug configuration.
