The BMC FM178/07 air filter provides a reliable response for the air intake of demanding roadsters. Designed by BMC, a recognised specialist in filtration elements, this replaceable component focuses on longevity and engine air cleanliness — ideal for the Yamaha YZF 1000 R Thunderace (2000/2001) and the FZR 1000 mentioned in compatibility.

• Monobloc construction without a weakening seal for enhanced mechanical stability.
• Special cotton filter media soaked in low-viscosity oil to capture particles while facilitating airflow.
• High-strength epoxy mesh resistant to petrol vapours and oxidation, to maintain its shape and efficiency.
• Washable and reusable cotton filter: maintenance possible with BMC cleaning products.
• Optimised airflow to reduce losses related to the intake circuit compared to traditional paper filters.

The performance of a cotton filter relies on four criteria:

• Permeability — limit resistance at the intake to preserve engine responsiveness.
• Filtration — prevent foreign bodies from entering the engine.
• Retention — keep captured particles within the filter matrix.
• Reusability — possibility of cleaning and reusing for repeated use.
