K&N High-Flow Panel Air Filter for BMW 3 Series 330d Diesel (E90/E91/E92/E93) 09/2008–2013 – Washable Reusable Cotton OEM Airbox Direct Replacement Engine Intake/Induction Filter Upgrade

High-Flow Panel Filter Upgrade for BMW 3 Series 330d 2008 to 2013

Give your BMW diesel the breathing it deserves. This K&N high-flow panel element is a direct-fit upgrade for BMW 3 Series 330d models from September 2008 to 2013 across saloon, touring, coupé and convertible variants (E90, E91, E92, E93). It replaces the standard paper element inside the factory airbox, unlocking sharper throttle response, stronger mid-range pull and a subtly deeper induction note while maintaining excellent engine protection.
