the problems i see with these along with the E3 plugs would be
1. you are lighting the fire from different points in the combustion chamber, and this may not matter in an all stock motor, but when a motor gets built i feel like to some extent you are changing ignition timing, everything happens in such a fraction that maybe it wouldnt matter, but i like the idea of lighting the fire at the same spot in the chamber everytime
2. once u put some miles on the new plugs and deposits start to collect, the current will always follow the path of least resistance, i feel after a few thousand miles, all that multiple spark positions will dwindle to just 1 spot on the plug
3. u ever here of indexing your plug, this is where u aim the open face of the plug towards (typically) the intake valve to allow the spark to be exposed to the fresh mix of the air/fuel, what i see with that new plug is a more shrouded spark same thing with the E3 plugs...
if wanting to run a good plug, use the iridium plugs with a fine tip electrode, this forces all the current out of one point and it will remain consistent
also they do have a plug with a built in compassator that stores energy and amps it up, this doesnt mean itll make more power, but it will help ensure the fire is lit everytime especially in alcohol, forced induction, or overly rich conditions
The only spark plugs I use in lew of the standard H-D plugs are the NGKs for the EFI engines.
Any EFI Harley that has the 4 pin coil connector utilizes the ION knock sense technology and the spark plug is the sensor for that circuit. In that context the spark plug does make a difference !
My 07 CVO was set up back in 07 with an SE pro tuner by Tilley's HD in NC when they added SE 10.5:1 pistons and SE 251 cams along with Rinhart tru duals. Ran fine. I seem to be running hotter now that the engine was opened up to 113". I was looking at the instructions on line for the old race...
Hello guys, ive done a full stage 1 with the SE Heavy Breather and Bassani radial sweepers. i have that selected on the FP3 and to me it feels like its running fine however the Eng management light keeps coming on saying both cylinders are running rich. Ive done about 6 Autotune sessions...
hey guys, just wondering if anyone had any suggestions of which cams they were putting in stock 88ci efi motors, it is an 04 night train, just looking to wake her up a bit, and i suppose i will need a new map downloaded? it has the big radius and heavy breather right now.
