K&N Washable Reusable Panel Air Filter for BMW 5 Series F10 F11 F18 520i 523i 528i Petrol (2010-08/2011) - Performance Intake/Sport Air Filter, Cotton Gauze, Lifetime OEM Drop-In Replacement, Direct-Fit Stock Airbox Upgrade

Lifetime Performance Panel Filter for BMW 5 Series F10 F11 F18 - 520i 523i 528i - 2010 to 08/2011

Give your BMW a sharper, freer-breathing intake with a genuine K&N cotton gauze panel element. This serviceable sports filter slots straight into the standard airbox on petrol 5 Series models listed below, helping the engine inhale more efficiently for crisper throttle response and smooth acceleration, while maintaining excellent dust protection.

Why this upgrade makes sense

• High-flow cotton media for improved engine breathing and stronger mid-range pull
• Reusable and washable - a one-time purchase that can be cleaned and re-oiled for the life of the vehicle
• Straight swap for the factory paper element - no coding, no remap, no cutting
• Engineered to work with the OEM ECU and sensors
• Long service intervals - often up to 50,000 miles between cleans under normal road use
• Backed by K&N’s Million-Mile Limited Warranty
• Cost-effective alternative to repeatedly buying disposable filters
