Left Intake Manifold DISA Valve Assembly 11617579114 for BMW Improved Engine Performance

Left Intake Manifold DISA Valve Assembly 11617579114 for BMW Improved Engine Performance Description

11617579114 / 11617560537 / 11617522929 Left Intake Manifold Baffle Regulator Assembly (DISA Valve) Key benefits Restores proper intake airflow control: replaces worn or failed DISA valve components to reestablish correct intake runner operation and engine breathing. Resolves common performance issues: helps eliminate symptoms such as reduced torque, poor throttle response, rough idle, or related diagnostic trouble codes caused by a faulty left intake manifold baffle/regulator. Exactfit replacement for vehicles using the listed part numbers: engineered to meet OEM form, fit, and function so installation is straightforward and reliable. What this part does The left intake manifold baffle/regulator assembly (DISA valve) manages the intake runner geometry to optimize engine torque and power across RPM ranges. When the assembly is defective, the engine can lose lowend torque and drivability suffers. Replacing this assembly restores the proper variable intake function. Key attributes Functionality: Variable intake runner control (left bank) - baffle and regulator mechanism that opens and closes to change intake tract length and airflow characteristics. Compatibility: Direct replacement for part numbers 11617579114, 11617560537, 11617522929. Designed for vehicles that require these OEM part numbers (verify fitment with your VIN or parts catalog before ). Fit & dimensions: Manufactured to OEMequivalent dimensions and tolerances for a proper seal and mechanical fit into the left intake manifold assembly. Durability: Built to withstand typical underhood temperatures and operating conditions associated with intake manifold service (materials engineered for intake system use). Performance impact: Restores correct intake runner timing, contributing to improved low and midrange torque, smoother idle, and normalized engine management behavior. Use cases / applications a failed DISA valve showing symptoms such as loss of lowend torque, fluctuating idle, or intakerelated error codes to restore original engine performance. Install during intake manifold service or engine maintenance to ensure a fresh, reliable baffle/regulator assembly and prevent future drivability issues. Use as part of a when diagnosing vacuum leaks or airflow irregularities on the left bank intake manifold to ensure the variable intake system operates correctly. Installation and notes Intended as a direct replacement for the left intake manifold assembly that uses part numbers 11617579114, 11617560537, 11617522929. Confirm compatibility with your vehicle by checking the VIN or parts reference. Inspect associated seals, gaskets, and vacuum lines during replacement to ensure a complete and prevent related leaks or faults. Professional installation recommended if you are not experienced with intake manifold components. Parts included Left intake manifold baffle/regulator assembly (DISA valve), corresponding to part numbers 11617579114, 11617560537, 11617522929. with confidence when you need an OEMequivalent left intake manifold baffle/regulator assembly to restore proper variable intake function and engine drivability.
