Product Description:

This set includes:

Partsklassik CDI Box 3 pin, New
   - Our true 450 Volt digital CDI in a new, US-made aluminum case
   - Won’t lose power as RPMs increase
   - Rev limit switch with multiple settings (default setting is no limit)

   - Factory-correct transformer coil for all Porsche CDI systems

3 Pin CDI Wiring Harness for stock distributors
   - Hand made in the USA by skilled workers

5K Ohm resistor*

Bracket and high quality decals are included.


*Replacement distributor rotors often have insufficient resistance for Porsche CDI systems. Check your rotor’s resistance, and if it’s only 0-1.5K ohms instead of the factory 5K ohms, then install the 5K resistor on your cap to coil wire. 3-Pin CDI systems also require solid core wires with 1k ohms resistance on each plug connector. Failure to maintain these values will void this set’s warranty.  See our Technical Service Bulletin for additional information.
