Direct Ignition Coil

**JerryHawk250** · 04-23-2018, 10:50 AM

Sunday while adjusting the valves and rejetting my carb I noticed that the insulations on the plug wire was cracked. I'm thinking about just changing out the coil and coil wire to a Direct ignition coil.
What do you guys think? I think it would be a better setup and would be a big improvement to the ignition system. I've been thinking about doing this for a while.

There's a universal kit but seems to be over priced and very poorly made.

That idea hadn't occurred to me before. I'll definitely be watching for your results, if you move forward.

Would love to see how this turns out! Great Idea.

It looks like any two wire direct ignition coil should work. I just need to physically put my hands on one and find one that isn't to long. I may just go down to the wrecker yard and pull one just to try out. I think the v6 Fords used a two wire coil.

I replaced the intake on my brothers 2001 ford 4.8 V8 and they had stout looking ones also! Probably easy to find.

It is an interesting idea. I plan on replacing the stock coil with a high output 3 wire cdi coil. The third wire being a ground to the head for the primary windings.

I replaced the plug wire but would like to just eliminate the plug wire completely. One less thing to worry about. It would be interesting to see how the high output 3 wire cdi coil works out too.

They break spark plugs. These on autos have the tube running down inside the valve cover that the coil sits in to brace it from vibrations. Something will need to be made up to prevent movement of the coil on the plug but it can't be too rigid either.

already thought about that. I would make a support bracket back to one of the valve cover bolts.

Then you, my friend, have it covered.

I had considered them on my GS. The spark plugs stick out of the sides of the head at an angle and would need considerable support. Plus they would be ugly and gaudy.

There's always the cheap DIY plasma ignition. A lot of vids on making the small simple circuits on youtube.

Here's an example.

A google pic of the top of a GS engine. See where the spark plugs are? That'd be a hard spot to do coil on plug.

Now that's a hot spark.

If you can get one to fit they are amazing!

Been running a Denso 2 wire setup since the second ride on the China Bike

You're the reason I was looking into it. lol. I'm trying to find one that will be shorter. From what I've found so far it looks like one from a 4 cylinder Ford Focus will work.

Good find. Those aren't as crazy expensive as some others.
