The performance edge!

The first Tech Session of 2025, held on a sunny March 22, welcomed Porsche enthusiasts with open arms and springtime vibes. This gathering was more than just cars and coffee; it was an opportunity to connect, learn, and celebrate the passion for Porsches. Hosts Tom Vagi and Max Rundlett set the stage with coffee, doughnuts, and an intriguing display of used and new oil samples, cleverly disguised as honey jars. Topics ranged from the importance of service records and routine maintenance, like replacing pollen filters and brake fluid, to winter storage preparations. Even the smallest details, like overfilling tires and safeguarding against pesky mice, were covered with engaging clarity.

There is so much mystery surrounding the CIS (continuous injection system) fuel system Bosch has dubbed K Jetronic, I wanted to try and make some sense of it for all Porsche owners. The bits of the system include the fuel pump, pre-pump on some models, fuel filter, accumulator, fuel distributor, warm-up regulator, injectors, auxiliary air valve, air sensor plate, cold start valve, thermo-time sensor and on newer models an oxygen sensor, frequency valve and mixture control unit were added.
