• A first layer of aerated foam traps dust, sand and impurities.
• The second, denser layer of foam stops even the finest particles, while facilitating airflow.
• Specially developed for Twin Air filters, the glue that holds the foam parts together is resistant to various solvents and petrol.
• Twin Air filters are significantly smaller than the original elements, to increase the volume available in the airbox and promote air circulation.
• The unique design of the "breathing seal" ensures maximum contact surface with the filter housing body.
• Bonding the two foam envelopes together eliminates the risk of dust and impurities becoming lodged between the two layers.
