With the Porsche models that use CDI now as old as 50+ years, many issues are negatively impacting these systems today. Some cars have been fitted with replacement parts that don’t conform to factory standards, and Bosch has discontinued many original parts. Factory specs, knowledge, and diagnosis skills have been forgotten and abandoned. General wear and tear takes its toll over the years. All of these factors contribute to system failures.

Advantages of 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
• Highly 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

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. When purchasing any CDI box from us, you are responsible for reviewing the warranty statement and following its conditions, including practices to be avoided and issue resolution.
