The Racor Eco Series Air Cleaners with the revolutionary spin-on design, completely disposable and supreme efficiency, offers faster, safer, more trouble-free service than any other air cleaner today. Built for rugged use, it combines maximum engine protection with fuel-efficient performance and long service life. The ECO Series provides two significant improvements in engine protection. When the filter loads with dirt, collected dust and debris stay safely contained inside the disposable housing, eliminating the chance of contaminating the air intake system during air filter service. Since the ECO Series uses no clean air gaskets, you never have to worry about gasket leakage. The ECO-SE has an elastomeric outlet that can be attached directly to a turbocharger or clean air ducting without the use of rubber adapters. This reduces the cost and complexity of the intake system.
