Filtrex Performance Air Filter. Filtrex Performance replacement air filter product guaranteed to increase horsepower and acceleration. Professionally engineered with a premium filtration material set within a high specification chassis, Filtrex will deliver increased performance and longevity over OEM and other aftermarket filters. Filtrex air filters consist of four sheets of cotton gauze layered between two sheets of strong galvanized steel mesh coated with epoxy. This rigid construction guarantees against deformation under heat and powerful engine forces. Deep pleating of the filter material increases air filtration area and enhances speed of airflow, creating an overall high performing filter product. Every filter is set within a frame produced from highly durable EPDM which is able to sustain extreme temperatures and still retain its form. All Filtrex air filters are tested on state-of-the-art German made MAHA LPS3000 dynometers, specifically designed for motorcycle and vehicle purposes. Fully washable and reusable Filtrex air filters are available for the majority of the latest sports and street bikes. Features and further details. To fit the following Suzuki’s.
