Direct-fit, washable foam air filter for the BMW X3 E83 with M52B25 or M54B30 engines - no mods, no trimming, no jiggery-pokery. Drops straight into the stock airbox.

• More airflow, less restriction - low-pressure-loss design sharpens throttle response and breathing efficiency
• Better filtration than paper - tri-foam construction + filter oil traps fine dust without clogging
• Reusable and long-lasting - clean and re-oil every 15,000-20,000 miles; lasts 4x longer than disposable filters
• Fast-road and track-day proven - trusted by UK drivers who want real-world gains, not just dyno theatre
