BMC FBTW70-140 Flat Twin Wire High-Performance Air Filter 70x140mm

The BMC FBTW70-140 is a high-performance replacement air filter from BMC's Flat Twin Wire (FBTW) series, engineered to deliver superior airflow and filtration efficiency over standard paper-element filters. Measuring 70mm x 140mm, this panel-style filter is designed for direct OEM replacement on a range of motorcycles, ATVs, and powersports applications.

BMC filters utilize a multi-layer oiled cotton gauze medium supported by a dual stainless steel wire mesh frame, a construction that provides exceptional filtration of dirt and debris while allowing significantly more air volume to reach the engine — translating to improved throttle response and potential horsepower gains.

Key Features:

• Multi-layer oiled cotton gauze filtration media for high flow and excellent particle capture
• Dual stainless steel wire mesh frame for structural integrity and long service life
• 70mm x 140mm panel dimensions for precise OEM fitment
• Washable and reusable — clean and re-oil instead of replacing
• Engineered to increase airflow volume compared to stock paper filters
• Made in Italy to strict BMC quality standards

The BMC FBTW70-140 is a cost-effective long-term performance upgrade. Rather than discarding the filter at each service interval, simply wash, dry, and re-oil with BMC filter oil to restore full performance. This filter is also known as a BMC foam air filter or performance gauze filter.
