Default Evo Ignition Coil

97 Heritage Softail. It has the dynatek 2000i ignition on it, and it currently has the stock coil.

I'm wanting to replace the coil as i suspect it is starting to have a few issues at times.

Are these as simple to install as taking out like 2 bolts? anything else I need to know to do when replacing one?

Anyone have any thoughts on the comp cams coil as a replacement?

Thanks guys.

The OEM coil is still available, $71 from the dealer.

The claim that it delivers more spark energy than the stock unit is BS.

Two bolts, two wires, and two plug wires. Assembly is the opposite of disassembly.

Easy installation for sure just pay attention to where the small wires go before you remove the one you have. FWIW and IMHO… unless you’re trying to squeeze every possible bit of performance outta your bike, stock coils are just fine. Even if you are, I’m not convinced there’s a significant gain from the aftermarket.

With the Dynatek 2000i, you can put in a single fire coil, it's just a matter of 1 switch on the Dynatek,
1 additional wire on the coil and making sure the plug wires are on the correct plugs.
So no more wasted spark.
But your way's definitely easier.

Easier plus, No Advantage to spending more on Single Fire.. Single fire is for Dual Plugs...and of course..Computer controlled Injection!!

How many plugs does he have, and WTF are you talking about, for computer controlled ignition?
He's buying a coil anyway, what's another $100.
