Genuine BMW Turbocharger Air Inlet Duct Sealing Ring for M57N2 Twin Turbo - BMW 13717799839
type: Product
description: Genuine BMW turbocharger air inlet sealing ring for M57 3.0L diesel engines This is the large-diameter genuine BMW rubber sealing ring that seals the air intake ducting to the turbocharger inlet on M57 3.0 litre diesel engines. It is a critical sealing point on the intake side of the turbo — any leak here lets in unmetered air and immediately upsets fuelling and boost control. Why replace this seal The ring lives in a hot engine bay and hardens, shrinks and cracks over time. Common symptoms of a failed or tired inlet seal include: Loss of boost or sluggish power under load Whistling, hissing or sucking noise from the turbo inlet area Limp mode and boost-pressure or air-mass related fault codes Rough or uneven idle from unmetered air entering after the MAF sensor A visibly perished, split or distorted ring on removal This is a single-use item. It should be replaced any time the turbocharger, intake ducting or air filter housing is removed — including during a turbo rebuild or an M57 engine swap. It is cheap insurance against chasing a boost leak later.
