Product Description:

Refurbished 6 Pin CDI Box for Exchange
Please send your Bosch core in first (address below).
All CDI boxes include free download of CDI System TSB.

Send in your old Bosch CDI box, and we will then send you back a refurbished original unit updated with our latest CDI electronics package. Our refurbished cases have been media blasted and come with new, correct decals.

The 6 Pin Digital CDI Box is for the 1978-83 Porsche model 911SC and 1978-94 model 930 vehicles. Please note that we can only accept and rebuild original Bosch cores, not aftermarket ones. We must receive and inspect your core prior to shipping the rebuilt unit.

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.
