K-Jetronic, KA-Jetronic and KE-Jetronic – Important information regarding purchase and replacement
Injectors for K-Jetronic (also called KA-Jetronic or KE-Jetronic at Mercedes) are an important part of the mechanical injection system. These injectors have a relatively simple technical design, but they do contain precision parts that wear out over time. Therefore, K/KA/KE-Jetronic injectors are wear parts that must be replaced in time in vintage and classic cars.
Inside each injector is a small spring that ensures the injector opens and closes at the correct moment. Additionally, there is a small strainer inside designed to retain fine dirt. Because this strainer cannot be removed (without completely disassembling the injector) and because injectors cannot be cleaned against the flushing direction, these injectors are practically difficult to clean. Replacement is therefore usually the best and most reliable solution.
Suitable for all K-Jetronic injection systems.

Manual for replacing injectors – K-Jetronic, KA-Jetronic and KE-Jetronic
Correct installation and a clean fuel system are important for the operation and lifespan of new injectors. Therefore, before installation, please read our manual containing important information regarding inspection, installation, testing, and preventing contamination and leaks.

New injectors can sometimes stick.
It sometimes happens that new injectors may stick slightly at first.
In practice, this problem usually resolves itself after short use.
Advice
Our advice is to always test new injectors before installation. In our own Mercedes Classic Garage, we therefore always test the spray pattern of new injectors before installation.
Tip: For a small additional fee, we can pressure test the injectors for you before shipment, so you can be certain that they open and close correctly and have the correct flow rate.
Follow all prescribed procedures and have the work performed by a recognized specialist to ensure correct installation and, consequently, faultless operation of the high-quality replacement parts. Incorrect installation or minor contamination can immediately lead to malfunction of the injection system.
