My 2003 Ultra Classic has a ton of engine and trans mods (has everything the 2012 has and much more) so I'm always trying something new. Making preps for my next trip at the end of the week so I installed a Power X Wing and E3 plugs. This trip will be about 1700 miles and should be a good test of both the X wing and the E3 plugs. I indexed the plugs to ensure I get the best combustion, with that said I'm also bringing the old HD plugs with me. I'll report back with any performance changes I see if any.
