BMW N54 Dual Cone High-Flow Air Intake Filters – Fits 135i, 335i, 535i (1 / 3 / 5 Series)

Unleash More Power from Your BMW with Our Dual Cone Air Filter Upgrade

Unlock your N54 engine’s true potential with our high-performance dual cone air filter set. The factory airbox design is highly restrictive, forcing both turbochargers to draw air from a single, shared intake path behind the front kidney grilles. Over time, this can lead to uneven air distribution and compromised performance — especially as individual turbos age.

Our dual cone setup solves this by giving each turbocharger its own dedicated air source, allowing for maximum airflow, smoother throttle response, and increased horsepower across the rev range.

Key Benefits:

• Boosts Horsepower & Throttle Response: Frees up airflow and improves turbo efficiency for a noticeable performance gain.
• Independent Dual-Cone Design: Each turbocharger gets its own 360° air intake for optimal flow and power delivery.
• Bold Red Filters for Engine Bay Style: Adds an aggressive visual upgrade to your engine bay.
• Secure, Thick Band Clamps Included: Ensures a tight, vibration-free fit during hard pulls and high RPMs.

Fitment: BMW E6X, E8X, E9X, and all vehicles equipped with the N54 twin-turbo engine.

Note: This kit does not include air ducting or intake piping — designed for use with stock or upgraded piping systems.
