Bonneville America Forums Forums Technical Forums Performance Mods spark

I have a 2004 America,Staintunes,AI removed,airbox removed,ini pod filters. Getting good results on the dyno and was thinkin of installing nology coils and leads for extra spark. Also nology plugs but hav NKG DPR8EA9's at the moment and nology only make an equivalent to DPR8EA's or DPR9EA's. Could I run one of these as an altrenative

The most critical spec is the thread reach and electrode length. If those are good, a variation of a step up or down in heat range or a variation in resistance isn't usually a big problem.
If the reach is off, the exposed threads may heat up to the point of causing pre-ignition. If the electrode length is too long, the plug could hit the piston.

Trev,it is going to be just a huge waste of your hard earned money if you buy those. You will not increase your engine output one iota. Some of the guys that put them on claim their bike runs smoother, that is a lot of money to have your bike run smoother. I was not aware these bike run ruff to begin with. You only need enought spark to light the fuel mixture, any additional voltage is not going to do anything. These are not high compression engines nor are they very high performance. That coil/wires are not going to make em that way either. Vegas
