The FunnelWeb CRF 300L pre-filter is designed to fit into the mouth of the air box intake, the open pore foam base of the pre-filter simply pushes into the snorkel opening and does not require anything further to hold it in place. This pre-filter will help to prevent dust from entering the airbox without any noticeable airflow restriction and can be easily removed and replaced without tools. Foam Profile: Designed and manufactured in Australia, utilizing the latest technologies in open cell foam 3D profiling, the pyramid profile effectively doubles the filters outside surface area without increasing its overall size and, compared with conventional foam air filters. Pyramid profile is designed to: Provide a 100% larger surface area Trap dust evenly over the increased outside surface area while allowing optimum airflow Maintain optimal airflow by spreading dust build over an increased surface area Effectively reduces the frequency of filter changes and cleanings
