This gasket seals the PCV valve to the valve cover. If this leaks, you maybe experience poor running conditions or check engine lights. Replace your leaking seal with a new Elring gasket to ensure long lasting reliability. 

Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!

Fits the following BMW engines:
M60 3.0L 4.0L
M62 4.4L

Transform the character of your E39 with the Luft-Technik Intake System from ECS Tuning.

ECS Tuning developed this intake with a focus on the E39's unique design challenges, particularly its one-of-a-kind factory airbox mount. By engineering a system specifically for this chassis, ECS ensures a precise, bolt-on fit that feels OEM while unlocking airflow the stock system leaves on the table.

At the core of the Luft-Technik system is a high-flow conical filter housed within a powder-coated aluminum heat shield, designed to seal against the hood and isolate the filter from engine bay heat. The result is a colder, denser air charge for improved combustion efficiency. A reinforced silicone intake elbow and precision-machined MAF housing maintain factory functionality while reducing turbulence, delivering smoother airflow straight into the engine.

The benefits are immediate: faster throttle response, a noticeable bump in induction volume, and a cleaner, more performance-oriented look under the hood. Pairing factory-style mounting points with premium materials like stainless-steel hardware, ECS created a system that not only performs but is built to withstand years of spirited driving.

For enthusiasts who want their inline-six to breathe freely and sound the part, the Luft-Technik Intake by ECS Tuning combines OE-level fitment with true performance engineering.

Key Features:

21% increase in flow over the stock intake
Seals to the hood for the largest and coldest air space.
Unrestricted airflow for maximum induction noise.
Retains full ASC function—no modifications needed.
Heat shield designed specifically for the E39, utilizing factory mounting locations to create a colder air pocket where the OEM inlet duct feeds.
5052 powder-coated aluminum heat shield for stiffness, corrosion resistance, and durability in demanding environments.
Black silicone intake elbow and coupler are compliant, high-temperature resistant, and designed to grip clamps securely through repeated heat cycles.
Retains the stock 3.0" MAF with no adapters required.
Designed to preserve the stock ICV hose.
Stainless-steel hardware included for long-term durability.
Fitment & Compatibility:

Tailored to the OBD2 M52B28 with ASC found in the BMW E39 528i.
Mounts directly to the factory frame rail with no modification required.
Designed to maximize available air space while retaining the OEM cold air inlet.

Product Development: The Luft-Technik Intake System was designed, engineered, tested, and quality inspected by ECS Tuning's Research and Development team. Their process incorporates industry-leading tools and methods, including FARO laser scanning for reverse engineering and quality assurance, SolidWorks 3D CAD modeling, in-house 3D printing for rapid prototyping, and rigorous long-term product testing. Performance data is validated using both a Mustang AWD 500 SE in-ground dyno and a Superflow SF-750 Flowbench to ensure precision and reliability.

Includes connector housing with terminals and seals. Commonly used for the idle air control valve (IACV).

ECS Tuning replacement harness connectors include all necessary pins and wire seals for a complete harness repair. Whether you have a broken harness connector or need a complete wiring repair, we have the components you need.

Each connector includes an additional terminal in case one becomes lost or damaged during installation.

 Maximum Flow Pro5R Filter

This intake kit replaces the top-half of both your factory air boxes. It features two 3-angle aluminum velocity stack adapters, 1.6mm powder-coated steel heat shields, trim sealed to seal out hot engine air, two custom aFe brand cotton filters, all hardware, and installation instructions.

This version uses aFe's highest flowing filter media, which uses a light oil gauze to filter out dirt and particulates while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.

By converting your stock intake air boxes, you are improving the most restrictive portion of your M5's intake system, increasing horsepower by 10 hp, torque by 10 lb/ft, improving acceleration as well as throttle response.
