Each CDI box we rebuild is fully tested on our proprietary testing equipment before it leaves our facility. There are however a number of installation factors, vehicle conditions, and practices that can make a CDI box appear non-functional, or that can actually damage the unit during or after installation. For this reason, we recommend that any CDI box be installed by a qualified Porsche mechanic who is truly competent with Porsche CDI ignition systems. We stand behind our CDI boxes with a 2-year warranty on defects in materials and assembly. 

With the Porsche models that use CDI systems now up to 50+ years old, there are many issues that negatively impact CDI box operation, including aftermarket parts that don’t conform to factory standards, discontinuation of original Bosch ignition parts, poor wiring and installation, and general wear and tear on the electrical system. These and other factors affect how well the system operates, and they contribute to ignition system failures. Moreover, the original Bosch units lose power as RPMs increase, and the circuitry is relatively unprotected from issues seen on these cars today.

Advantages of using the Partsklassik CDI:

• “A” Terminal Disconnect protection
• Protected Trigger Signal Input Filter
• Input Voltage Correction
• End User Settable RPM Limiter
• Misfire Over Voltage Protection
• True 450 Volt Primary CDI
• High Efficient Design Resulting in Less Heat Generation
• Low System Current Draw
• Won’t Lose Power as RPM Increases
• Plug compatible with all factory Porsche Models
• No Phase Modification on Trigger/Firing Point
• 2 Year Warranty Against Defects in Materials and Assembly

Please note that while Partsklassik CDI boxes have built-in protections from external issues, these protections are not infinite. It is still important to maintain and service your electrical and ignition systems properly. This includes the often overlooked specs on secondary resistance values (i.e., on plug wire connectors, rotor, cap-to-coil wire).
