Black Ignition Coil

[healeyman]

So I may be the last person here to learn recently that Bosch ignition coils are backordered since forever with no delivery dates yet in sight. I'm  in need of a new or near new black coil (Bosch 00010) for my '76.

What are people doing currently with respect to replacements/substitutes?

Thanks.

May have to go after market, this one should work provided the stock resistance wire is still intact.

lol @ Bosch coil........ if you don't have a 10 point show car waiting to get judged at the next event, just go to a NAPA store near you and they will have several different option for you.

New Bosch coils do not have a great reputation. 
 

A lot of Porsche guys run 30-40 year old coils and carry a spare equally old coil. A good “old” Bosch coil is very reliable. 
 

MSD high vibration blaster coils work well if they fit your application.

I finally "caved-in" and replaced the stock points and coil on my '76 with a PerTronix ignition module and coil.

PerTronix Ignitor II (p/n: 91847V) with a 0.6-ohm Flame-Thrower II Coil (p/n: 45011).

You bypass (or remove) the resistor wire.

I try to keep my car tuned as best I can with the stock components (original owner), but after making the change to the ignition, I noticed a big improvement in starting, idling and cruising. Better fuel mileage too!

I'll never go back!!!

Very helpful responses from everyone, thanks.

My take away is rather than waiting for Bosch coils to be available once again, perhaps I should seek out an aftermarket coil suitable for my application, including possibly a PerTronix unit, since I am already running a PerTronix Igniter II as John suggests, along with a black Bosch coil that looks like it might be original to the car. 

Thanks all for your replies.

Matt,

The original black Bosch coil is 1.9 ohms plus the resistor wire (0.9 ohms) gives a total coil resistance of 2.8 ohms.

If you keep the Bosch coil, be sure to bypass the resistor wire. 

PerTronix recommends a 0.6 ohm coil for the Ignitor II with NO resistor.
