See below for address to send your Bosch core in.

Send in your old Bosch CDI box. and we'll send you back a rebuilt Bosch unit updated with our advanced digital CDI electronics package. Our rebuilt units have been media blasted and come with correct decals. Please note that we only accept and rebuild original Bosch cores, not aftermarket units.

In addition to the many robust design features mentioned further below, 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.

Feb 2018 Press Release:
After 5 years and over 650 units sold worldwide we have just released our latest version of the Digital CDI box for Porsche models 1969-77 3 Pin versions and 1978-94 6 pin CDI versions for the 911SC, (up to 1983) and 930 models.

 With the Porsche models that use CDI systems now up to 50+ years old, we have seen so many items that can influence CDI box operation. With many cars being fitted with aftermarket parts that don’t conform to factory standards, Bosch discontinuing original parts and general wear and tear on the electrical system, all these things can not only affect how well the system operates but can also contribute to multiple system failures.

Advantages of using the Partsklassik CDI over repairing or replacing with another unit:
“A” Terminal Disconnect protection
Protected Trigger Signal Input Filter

End User Settable RPM Limiter
