Intake Manifold Gasket Kit 6-Piece for BMW N52 N54 N55 M57 325i 335i
Eliminate unmeasured air leaks and restore precise fuel metering in your BMW with this direct-fit 6-piece intake manifold gasket kit. Factory seals degrade over time due to repeated heating cycles and vibration, allowing unmetered oxygen past the mass airflow sensor. This replacement set replicates OE 11617800585 and corrects the root cause of rough idling, hesitation under load, and persistent DTC codes like P0171 or P0174. By establishing an airtight barrier between the intake manifold and cylinder head, the kit returns the engine control unit to calibrated airflow parameters and reinstates predictable throttle response.
Installation & Maintenance Tips
- Surface Preparation: Strip all residual gasket material and carbon deposits from mating flanges before installation to guarantee uniform clamp loading.
- Torque Sequence: Fasten manifold bolts in the specified crisscross pattern and follow degree-by-degree tightening steps to prevent flange warping and repeat leaks.
- System Reset: Clear adaptive fuel memory via your diagnostic interface after assembly so the ECU relearns optimal trim values with the new seal in place.
