Detailed Description

Wix 49461 is a replacement engine air filter engineered for BMW intake systems that call for a panel filter in this size and configuration. Its cellulose media and moisture-resistant treatment are intended to maintain airflow control while capturing contaminants during stop-and-go traffic, short trips, dirt-road use, construction-zone driving, and highway travel. This part cross-references BMW (e.g., 13 71 7 556 961) for the same application.

Compatible BMW fitment includes 2007-2011 BMW 335i, 2007-2008 BMW 335xi, 2008-2010 BMW 535i, and 2009-2013 BMW Z4 applications, along with additional BMW coverage listed below. The Wix 49461 is also a direct reference point for buyers searching for a BMW 335i air filter, BMW Z4 engine air filter, or BMW 535i panel air filter replacement.

What It Helps Address

• Restricted airflow caused by a dirty or loaded engine air filter.
• Dust and debris entering the intake system during severe driving conditions.
• Moisture exposure that can shorten filter service life.
• Fitment uncertainty when replacing the original BMW air filter by part number.

Installation Notes and Tips

Verify the filter dimensions and OE reference before installation: 14.016 inches long, 11.339 inches wide, and 1.614 inches high. The closed top design and panel format should match the factory airbox configuration on the listed BMW applications. Replace the filter at the OEM air filter change interval or sooner if driving conditions are severe.

Quality Assurance

Wix Premium Panel Air Filters are recommended for OEM air filter change intervals and are laboratory tested to ISO 5011 standards. The Wix 49461 is built to deliver durable filtration performance for BMW 1 Series M, 135i, 335i, 335is, 535i, and Z4 applications.
