Crankcase Breather Filters

3 products

Our Crankcase Breather Filters range for Harley-Davidson keeps oil vapour under control on Sportster, Dyna, Softail, Touring and Evolution V-twins. Supplied by Iron City Motorcycles, an Iron City authorised HD dealer in Leeds, these breather filters capture mist from the engine cases and stop it soaking the air filter or staining frame paint. MCS supplies the core of the range with neat, bolt-on solutions that suit bikes running open intakes or high-flow filter kits. Whether you are building a hot-rod Harley-Davidson, cleaning up an older bike that is throwing oil, or fitting a new air cleaner that needs separate breather routing, our catalogue has the parts you need. Every order ships from UK stock with quick despatch and workshop-backed advice from Leeds. Browse the full range below.
