Core-Driven Innovation | Redefining Aftermarket Excellence
Product Introduction
This product is a high-quality repair kit specifically designed for the intake systems of mainstream European diesel engines, particularly the BMW M57/M57N2 series. The kit integrates all critical sealing elements required at the connection between the intake manifold and the cylinder head. It is engineered to resolve issues such as air leaks, unstable intake pressure, and illuminated engine fault lights caused by aging Swirl Flap seals.
As a professional manufacturer of intake system components, our product is manufactured strictly according to factory specifications. It ensures superior sealing performance even in harsh environments characterized by high temperatures, high pressure, and oil vapor exposure.
1. Comprehensive "One-Stop" Repair Kit
No need to source gaskets, seals, or flap covers individually. We provide a complete solution containing all necessary replacement parts.
Includes: 6 Flap Covers, Intake Manifold Gasket Set (Upper & Lower), and Vacuum System Seals.
Customer Value: Reduces sourcing time, prevents installation delays caused by missing parts, and ensures a successful one-time repair.
2. Upgraded Wear-Resistant Materials – Fixing the OE Design Flaw
Bench durability test data indicates that the primary cause of OE intake manifold failure is excessive friction between the plastic actuator drive lever and the stop block under high-frequency engine vibration, leading to plastic adhesion or seizing.
Technical Optimization: Our flap's key contact surfaces utilize a metal-composite structure, effectively avoiding the physical adhesion at high temperatures seen in the OE "plastic-on-plastic" design.
Data Support: The improved material solution has passed over 200 hours of engine bench durability testing, completely resolving the VGIS seizing issues caused by friction welding mechanisms.
3. High-Temperature Resistance & Precision Sealing
Heat Resistance: Constructed from NBR/FKM (Nitrile Rubber/Fluoroelastomer) composite materials. The temperature range covers -40°C to +220°C, far exceeding the weathering limits of OE EPDM rubber, effectively resisting corrosion from coolant and engine oil.
Sealing Pressure: The gasket design withstands intake pressures up to 2.5 MPa, ensuring no leakage when the turbocharger engages and maintaining stable air-fuel ratios.
Suitable for models equipped with BMW M57 (3.0d) and M47 (2.0d) series 6-cylinder diesel engines. This covers major BMW models in European and US markets, as well as select Land Rover models.
Technical Parameters
Application Scenarios
1. Eliminating the Risk of Severe Engine Damage from Swirl Flap Failure
Scenario: In BMW M57 and M47 series diesel engines (especially 1999-2009 models), the intake manifold contains swirl flaps. After prolonged use, the flap shafts wear out, causing the metal or plastic flaps to detach and get ingested into the engine cylinders. This can lead to severe damage to pistons, valves, or even total engine failure.
Our Solution: As a core component of the Swirl Flap Delete Kit, this product uses high-precision gaskets and blanking caps to perfectly seal the flap shaft holes after removing the risky original flaps. This fundamentally eliminates the risk of engine destruction caused by flap detachment, making it a classic solution recommended by professional auto repair shops in Europe and North America.
2. Repairing Intake Air Leaks and Restoring Engine Performance
Scenario: As vehicles age, the original rubber intake manifold gaskets (OE: 11617790198, 11612246945) at the connection between the intake manifold and cylinder head harden and lose elasticity due to high heat, leading to vacuum leaks. Symptoms typically include rough idling, lack of acceleration power, black smoke, and increased fuel consumption.
Our Solution: The various gaskets included in this kit (molded seals, rubber seals) are specifically designed for BMW M57/M47 engines. They perfectly replace aged OE parts and restore the airtightness of the intake system. Installation effectively resolves idle vibration issues and improves fuel economy, meeting the high maintenance standards for older vehicles in European and US markets.
3. Meeting Strict Emission Regulations and Eliminating Fault Lights
Scenario: In European regions implementing EU3 and EU4 emission standards, as well as US areas with strict emission testing, intake system leaks or flap failures will trigger the Check Engine Light, causing the vehicle to fail annual inspections.
Our Solution: Repairing with this product completely fixes vacuum leaks caused by poor sealing or flap failures, ensuring accurate engine intake data. This effectively clears fault codes and helps customers pass vehicle inspections, making it especially suitable for high-volume classic BMW models like the E46, E90, E60, E83, and E53 in European and North American markets.
Installation Guide
Step 1: Remove components.
Step 2: Remove the intake manifold and take out the old parts.
Step 3: Clean the surfaces.
Step 4: Install the new gaskets.
Step 5: Install the blanking plates.
Step 6: Install the intake manifold.
Troubleshooting & Technical Support
Q1: What is this repair kit for? What symptoms indicate that I need it?
A: This repair kit is designed to fix failures in the intake manifold runner control system. If your BMW engine exhibits the following symptoms, it typically indicates that the intake manifold actuator or linkage mechanism is damaged:
Check Engine Light: Illumination with fault codes such as P2004 (Intake Manifold Runner Control Circuit/Open) or P2015 (Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance).
Reduced Power: Especially sluggish acceleration or hesitation at low RPMs.
Rough Idle: The engine may shake or "surge."
Unusual Noises: In some cases, you may hear a "clicking" or "rattling" sound from the intake manifold area, caused by a loose linkage or actuator striking other components.
Q2: Do I need to buy other parts for installation besides this repair kit?
A: To ensure a smooth repair and proper sealing, we strongly recommend purchasing the following consumables:
Intake Manifold Gasket: Once the intake manifold is removed, the original gasket is likely to lose its elasticity. To prevent future air leaks, we recommend replacing it with a new one.
Injector Seals (Optional): Depending on the model, if you disturb the injectors during disassembly or if the vehicle has high mileage, it is advisable to replace the lower injector seals to prevent fuel leaks after reassembly.
Q3: Which vehicles is this repair kit compatible with? How do I confirm the fitment?
A: Your product, corresponding to specific OE numbers, is primarily suitable for BMW models equipped with N52, N54, and N55 engines (such as the 3 Series E90/E92, 5 Series E60, X5 E70, etc.).
Verification Method: You can find the "Vehicle Fitment" list at the bottom of our product page or use the vehicle selection tool to enter your VIN or specific year and model to confirm. If your vehicle has fault codes P2004/P2015 and inspection reveals a broken plastic lever arm, our kit is the correct choice.
