image.jpgTrying to identify this piece via my layman’s description: small canister adjacent/attached to the side of the coil plate. It has a short, single-wire lead to a male connector.
Thanks for the help!image.jpg

That’s a capacity or “radio noise suppressor”. It protects the cars electrical system from voltage spikes from the coil. Supposedly they are filled with electrolyte and can dry out. When this happens, you can get noise in your radio, and your sensors will not read right because they are also picking up the noise.

Shovel has a good video on it, I watched it a while back. Pretty interesting.

This is what came up & LMR. Not the same piece and the connector is not male. I’ll keep Googling!

Nope. Disregard my last reply. My crappy internet finally downloaded the video and it makes total sense now. Sorry for my earlier reply! You were 100% correct and I thank you for the attached video which explains it perfectly.
Cheers! And thank you again!!

pretty sure they quit making them some time ago. Again the only reason you should need it is if you hear the ignition noise in the stereo. It will be a whistling noise that goes up and down with the rpms, an audible tachometer basically....

These are very common components in the classic car world. You just need to know the capacitance of the old one to replace it with one from a different car. I the past they were installed directly on distributors.

Barring that, you could buy any old capacitor that can handle the voltage and has the right capacitance and just wire it up. The biggest issue with using one that's not automotive grade will be the heat and disability of the wires coming off it, the leads on a typical through-hole component will be a little weak for automotive use. There may be industrial grade options out there, maybe McMaster carr has them, I haven't bothered to look as mine has held up fine for 31 years.

I looked through my mustang electrical bible hoping they might happen to have the cap ratings but it does not list it. A quick search shows that the one shown above is the replacement for our model. Realistically it has a different design to the cap and a different harness but I don't think either of those should be deal breakers. You can cut the old cap from the wire/harness and solder the wire to it and figure out some way to attach it.

From what I have been told in my installing days was that these were used to reduce noise mainly on am radio which is why they were not used on later models, no one cared what am sounded like then or now. So again unless your noticing noise in your stereo it isn't a something that helps add hp or that is necessary for the car to run.

Dang it. I was told an upgrade would add 100hp! J/K

I guess I’ll just put on the replacement and lower my expectations… ho-hum!!

Thanks gents for the info and feedback. As always I appreciate it and have benefited from your help. Cheers!
