Ciro has re-invented the timeless round air cleaner by creating their very own high-flow, ultra low-profile air filter to be the heart of the new Ciro Tri-Bar air cleaner. A full 1 1/4" thinner than stock, while flowing significantly more air, your leg will not notice this air cleaner, but your engine most definitely will as the Ultra-Flow filter produces a massive 45% increase in air flow over a stock 2014 air filter. The innovative design also incorporates an OEM style crank case breather. Fits all 2008-2016 Touring and Trike, as well as Fuel Injected Throttle-By-Wire Softail and Dyna thru 2017.
