We believe that installing this Electronic Ignition in your pre 1973 Mercedes Benz 4 CYLINDER GAS ENGINE is absolutely the best upgrade you can make to your old classic. Elimination of the contact breaker points is the key to this modification. In its place there is an optical trigger with a light beam that is broken by a rotor that has small slits in it (see picture below). There are no points to burn, wobble, corrode or adjust. Along with the optical trigger an electronic ignition module is used to boost the intensity of the spark across the spark plug electrode. You will be amazed at just how well this unit works.
We cannot confirm application for EURO MODELS. If you have a Euro model please do not order!

PLEASE NOTE: In both videos Kent refers to this unit as the "CRANE IGNITION." As of the fall of 2016 the name has been changed but it is still the same unit in design and application.
Here are the advantages of installing this electronic ignition 1. Faster starts in the morning thus saving battery and starter 2. Smoother idle and cleaner fuel burn producing less smoke 3. No more constant fouling of spark plugs 4. More power and faster acceleration 5. Better fuel economy 6. Easier starts after long storage (no points to corrode) 7. Loose distributor shaft bearings do not affect performance 8. Easy to change back to original points if need be When you consider all these advantages it is pretty hard to argue for any reason why not to do it, especially when you consider the moderate costs involved. The unit does come with complete instructions and adapters to install in a variety of old car makes. This means the factory instructions are lengthy and may overlap to cover all the different styles of distributors on the market. It may be confusing to determine just what procedure you need for your Mercedes. Kent's included manual was written to supplement the manufacturer's general instructions and his manual is specific to Mercedes Benz. These instructions will eliminate trial and error and greatly speed up the installation process. Just follow along step by step and you will be done in less than 2 hours.
The printed manual that we include with this kit covers installation in a 6 cylinder engine. All of the install procedures and adjustments are the same except for installation of the 4-slot rotor disk (shutter). This procedure is included in a supplemental video done by Kent that is also included free of charge. This picture shows how the rotor disk is installed using the techniques show in the supplemental video instructions.
