BMC FB348/04 High-Flow Cotton Panel Replacement Air Filter

The BMC FB348/04 is a high-performance replacement panel air filter engineered to drop directly into your vehicle's factory airbox in place of the stock paper filter. Built with motorsport-derived technology, this filter delivers increased airflow and superior filtration efficiency compared to standard OEM paper elements.

Key Features:

• Superior Filtration: Captures airborne contaminants as small as 7 microns — compared to 10 microns for a typical OEM paper filter — for cleaner air and better engine protection
• Multi-Layer Cotton Gauze Construction: Filter media consists of multiple layers of cotton gauze soaked in low-viscosity oil, providing excellent air permeability and particle capture
• Epoxy-Coated Alloy Mesh: Protective alloy mesh with epoxy coating shields the filter media from fuel vapors and moisture-related oxidation
• Full Moulding Manufacturing: Produced from a single mould with no welded corner joints, eliminating common failure points and ensuring long-term durability
• High-Quality Rubber Surround: The rubber gasket seal offers outstanding adhesion to all factory airbox shapes and sizes, preventing unfiltered air bypass
• Washable & Reusable: Pre-oiled at the factory and designed to be cleaned and re-oiled using a BMC regeneration kit, saving on long-term replacement costs
• OEM Drop-In Fit: Installs directly into the stock airbox with no modifications required
• 1-Year Manufacturer Warranty

BMC has been producing high-performance air filters since 1973, with technology originally developed for Ferrari's Formula 1 program. The FB348/04 brings that same F1-derived engineering to your street vehicle, offering a straightforward performance and filtration upgrade over the factory paper filter.
