Constructed with corrosion-resistant aluminum motor housing, reinforced durable impeller blades, and high-temperature sealed internal wiring connectors, this air injection pump matches all original mounting bracket holes, electrical plug pin layouts and air outlet pipe dimensions. It installs at the front engine bay secondary air circuit position, fitting all production years of E-Class and ML-Class E350, E550, ML350, ML550 without cutting, drilling or custom adapter modifications.
This upgraded secondary air pump resolves common factory part flaws including thin plastic impeller cracking, weak motor winding insulation, loose electrical terminal corrosion, and premature motor burnout after repeated cold-start cycling. The reinforced internal motor winding design delivers consistent air flow pressure across all temperature ranges, extending service life far beyond stock pumps. Pre-assembled with fully sealed wiring connectors and pre-aligned mounting feet, it enables direct bolt-on replacement to drastically cut labor time for DIY mechanics and professional repair shops.
