I know they are pricey, I go oem. Might try DB electrical, had good luck with their stuff. Never bought coils there tho.

greatly appreciate info. Looking back can see couple revisions since my stock 03, so they had a good run. Thanks again.

I know this post is a yr old but I have a question about the coils. Is there any reference to using this 1-amp coil on an older Optimax 135 which used the 3-wire inductive coil? I realize that the old system used the ECU trigger - cylinder head ground - and Power. The wire would need a sensor ground ( i could pull that from the tps ) - Battery Ground ( pulled from the starter ground). Has this been done or could you foresee a problem?

DIY Autotune has the same coils without the built-in ignitor... for either inductive or CDI ignitions, if that's what you're after?
