Damaged internal vanes commonly trigger Check Engine lights, cause harsh cold starts, and allow uncalibrated air into the combustion chamber. This aftermarket intake blocker permanently seals the disconnected ports using machined 6060-T66 billet aluminium and high-temp Viton sealing rings. Mechanics and DIY owners install this straightforward swap to stabilize idle speed, restore full turbo boost, and prevent expensive downstream sensor damage—all while bypassing the recurring failure cycle of the original plastic mechanism. Cross-compatible with reference numbers 1168515685 and 11618507335, the unit mounts directly onto existing manifold studs without requiring fabrication or welding.\u003c\/p\u003e \u003ch3\u003eInstallation Benefits \u0026amp; Technical Tips\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFit during a standard intake manifold removal to save labor hours and avoid repeated disassembly later.\u003c\/li\u003e\n\u003cli\u003eAlways torque fasteners to factory specifications to prevent flange warping or compromised seal surfaces.\u003c\/li\u003e\n\u003cli\u003ePair with a fresh cabin air filter change after swapping airflow configurations to maintain optimal HVAC efficiency.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConstruction Material: 6060-T66 billet aluminium alloy\u003c\/li\u003e\n\u003cli\u003eSealing Components: Temperature-resistant Viton gaskets and O-rings\u003c\/li\u003e\n\u003cli\u003eOEM Replacement Reference: 1168515685 \/ 11618507335\u003c\/li\u003e\n\u003cli\u003eCompatible Engine Codes: N57N, N57Z, N57X\u003c\/li\u003e\n\u003cli\u003eFuel System Application: Direct injection diesel models only\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cb\u003ePackage includes:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1x Swirl flap deletion plug\u003c\/li\u003e\n\u003cli\u003e6x Pre-cut sealing gaskets\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eSafety Warning \u0026amp; Fitment Reminder\u003c\/h3\u003e\n\u003cp\u003eThis plug is strictly designed for the revised N57N, N57Z, and N57X engine iterations.
