Mercedes SEL 1990 Peace, mercy, and blessings of God be upon you. Dear owners of Benz W126, W124, and other cars that have a G-Tronic injection system distributor. 🔴 The well-known WJ brand, which manufactures and designs most of the parts that fail in European cars like Mercedes, BMW, Bentley, Rolls-Royce, and others.. We have the automatic "shoulder" part from WJ, located next to the distributor. It is a very important part of the distributor's components and constitutes 50% of the system. It is responsible for fuel economy, as well as torque and pulling power of 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 sluggish. - Black smoke (carbon) from the exhaust. - Very high fuel consumption. 🔴 It can be provided to Gulf countries via international shipping ✅ For any inquiries, please message me via WhatsApp or Snapchat: MR560RR. Best regards.
