1980 Porsche 911SC CDI Ignition Coil by Partsklassik

Product Description:

CDI Ignition Transformer  
We have developed this coil to work with the Porsche CDI system and give you the strongest, cleanest spark. This coil is designed to replace the 901.602.502.00 Bosch coil. Our coil comes with decals and post hardware, as well as a free CDI System TSB download. Bracket is also included.

Capacitor Discharge Ignition systems use a transformer, aka the CDI coil. It has a turns ratio of 100 to 1 so the voltage going in is multiplied 100 times to give you the voltage needed for the Porsche CDI system. These are high-energy systems and therefore extremely dangerous. If you are not trained to work on these systems, bring your vehicle to a professional, fully insured Porsche mechanic who is.

We stand behind our coil with a 12 month replacement guarantee when used within Porsche factory specifications for the complete system, using a Bosch or our CDI unit, solid core factory ignition wires, and the correct spark plugs. Factory resistance values on plug wire connectors, rotor, and cap-to-coil wire must be maintained. Many replacement parts fail to meet factory specs. Contact us for additional information.


PLEASE NOTE:
CDI systems often fall out of spec over the years. Incorrect resistance values, insufficient connections and grounds, bad wiring, and incorrect replacement components are a few of the culprits. In time, these conditions can and do cause premature, sudden, and inconvenient component failure!

Consult your Porsche factory shop manual for proper specifications and installation info, or seek out a Porsche specialist who uses factory shop manuals and is capable of fully diagnosing the entire ignition system.  An oscilloscope is an essential tool for troubleshooting a CDI system. We recommend checking out the oscilloscope blog at www.klassikats.com for a few examples.

If you replace a bad coil without ensuring your CDI system is free of issues, you may find yourself replacing the coil again, regardless of brand. Call or email us at Partsklassik for further information.

After returning 6 failed Bosch Silver Coils I am completely satisfied and overjoyed with this PartsKlassik coil and attendant 5,000 Ohm resistance wire going from the coil to the distributor cap. In addition, I am very pleased with the customer service provided by Mike. Thank you very much!!!
