ECS Tuning E39 528 Luft-Technik Intake System - With ASC

Unlock more character and performance from your E39 with the ECS Luft-Technik Intake System.

Designed by BMW enthusiasts for BMW enthusiasts, this intake was engineered specifically around the quirks of the E39 chassis, including its unique factory airbox mount not shared with any other BMW. The result is a clean, direct-fit solution that feels as satisfying to install as it does to drive.

Featuring a clever MAF housing design and factory-style mounting details, the Luft-Technik intake combines precision engineering with enthusiast passion. Once installed, you’ll notice sharper throttle response, a richer induction growl, and an engine bay that looks every bit as purposeful as it sounds.

Whether you’re chasing a more spirited driving experience or simply want to hear your inline-six breathe, the ECS Luft-Technik Intake delivers performance, sound, and style in one complete package.

Key features:

• 21% increase in flow over the stock intake
• Seals to the hood for the largest and coldest air space.
• Unrestricted air flow for maximum induction noise.
• Retains full ASC function, no modifications needed.
• Heat shield designed to fit the E39 chassis perfectly, utilizing factory mounting locations and creates a colder air pocket where the factory inlet duct is.
• 5052 powder-coated aluminum heatshield, stiff, corrosion-resistant, and finished for a long life in the swap environment.
• The black silicone intake elbow and coupler is a compliant, high-temperature silicone that grips clamps and resists blow-off during repeated fitment and heat cycles.
• Retains stock 3.0" MAF, no adapters needed to run the stock MAF in a factory-like location.
• Designed to preserve the stock ICV hose
• Stainless-steel hardware for longevity and corrosion resistance.

Fitment & compatibility:

• Specifically engineered to work with utilizing that maximum air space and retaining the OEM cold air inlet. Mounts to the factory frame rail, no modification required.
