Mercedes SEL 1990 Brothers, owners of the Benz W126, W124, and other cars that have a G-tronic fuel injection distributor. 🔴 The well-known WJ brand for manufacturing and designing most of the parts that fail in European cars like Mercedes, BMW, Bentley, Rolls-Royce, and others.. We have the automatic shoulder piece, W.J., which is installed next to the distributor. It is a very important part of the distributor responsible for fuel economy, as well as torque and pulling power in the car. It is for Benz 560, 420, 300, E230, and E190 models. 🔴🔴 Symptoms of shoulder failure in your car 🔴🔴 - Weak torque and the car feels choked - Black carbon smoke from the exhaust - Very high fuel consumption 🔴 It can be provided to all Gulf countries via international shipping... For any inquiries, please message me via WhatsApp or Snapchat mr560rr.. Greetings to you.
