DISA Valve O-Ring Seal — BMW M52 | OEM 11617504543
Replace the DISA Valve O-Ring Seal on Your BMW M52 — Stops Air Leaks and Restores DISA Function.
The DISA (Differentiated Intake System) valve on BMW M52 petrol engines uses an O-ring that hardens and cracks with age — causing air leaks at the DISA valve mounting, rough idle, and loss of low-end torque. This direct replacement O-ring restores an airtight DISA seal.
Vehicle Compatibility
BMW 3 Series E46, 5 Series E39, 7 Series E38 — with M52 2.0L, 2.5L, 2.8L petrol engine
