are s2000 & k-series coilpacks interchangeable

6spd_EK · Dec 9, 2009

are s2k & k-series coilpacks interchangeable? I read on s2ki that the coilpacks are interchangeable (someone there ran k packs on a s2k @ a roadrace event) but was hoping someone could verify.

if you must know why I am asking - I know someone with a turbo s2k & was wondering if they could test a set of (k-series) okada coilpacks.

thanks in advance

i think i was looking at the honda part numbers and after 06??? the s2k ones are the same part number as EP3's...not sure what the difference was before then.

Before 06 they were about 1 to long

also before 06, they were prone to failure . . . the newer s2k coil packs are the exact same as the K

What about AEM coils?

Slociviccoupe · Dec 13, 2009

aem coils are the same denso coils used on most sport bikes. they are 2 wire dumb coils and need a cdi or igniter wired to fire them where as the k and f coils are 3 wire smart coils with a built in igniter. coil gets a switched ignition, ground and a trigger from the ecu. 3 wire coils have a built in igniter.
aem coils won't work without either msd cdi or aem c2di. denso coils are 100/1 turn ratio. aem cdi is 520 volts to the coil. so 52k ends up at the end of the plug. I ran that setup on my ctr motor for 4 years and never had an ignition problem. Im hopin i never have a problem with my 05 s2k with coil packs.
