This MEAT & DORIA EGR valve, part number 88129, is designed to regulate the flow of exhaust gases back into the engine's cylinders.

Proper functioning of the EGR system is crucial for meeting emissions standards and maintaining engine efficiency. A faulty EGR valve can lead to increased emissions, rough idling, poor fuel economy, and potential engine damage. MEAT & DORIA is a trusted brand known for its quality automotive components. This EGR valve is manufactured to meet or exceed original equipment specifications, ensuring a reliable fit and dependable performance for your vehicle.
