FunnelWeb Filter uses a unique pyramid profiled foam. This design vastly improves the dirt holding capacity while delivering consistent optimum air flow. All FunnelWeb Filters utilize the latest technology in open cell polyurethane foam profiling, this substantially increases the filter’s surface area enabling it to trap far more dirt on its outside surface preventing harmful dust from penetrating through. *Works with any foam air filter oil.
