    Heavy Breather Performance Air Cleaner is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from Nice Product I purchased this in conjunction with the HD high flow exhaust, protuner and smart tune. They work flawlessly together and really improved the throttle response as well as the overall power of my 18 Road King Special. The blacked out version I have goes perfectly with the look of the bike. I can't say how it would do by itself, but I am very please with it in this combination. It really feels like a totally different, much better bike.

    Rated 5 out of 5 by from Optimize your Stage 1 in style Had this installed at the dealership as part of a Stage 1 before even taking home my RKS, so I cannot comment on the ease of installation. The new design definitely takes up less space than the previous one. At 6'2", my knee does still touch the curved metal piece, but it's not really an issue. In my opinion, this style of intake looks better, and is more aggressive than any of the other Screaming Eagle air intake options. I believe it also allows more air into the engine than the Hi-Flow or Ventilator. After engine break in, I had the Stage 2 torque cam installed, and now I can actually hear the heavy breather sucking air into the engine. Makes me happy I chose this option vs any of the others.

    Rated 5 out of 5 by from Great looking part Great looking part really goes well with the bike, install instructions were very good only took 15 minutes to install. I would buy this again, a little pricey but worth it in the end

    Rated 5 out of 5 by from New Design I love the new profile. HD squished the air cleaner such that it does not interfere with your leg. Old style stuck out further. Love the look. Great part of a stage 1 upgrade.

    Q & A

    Is this air filter a k&n oiled filter or is it a dry air filter?

    Asked by: Johnhall
    Hello Johnhall, This is a K&N Air filter. The use of cleaning, drying or oiling methods or products other than those shown, damages the filter and can void the manufacturer's warranty. K&N® Air Filter Cleaner is available from a Harley-Davidson dealer, either alone [0.95 L (1 qt) sprayer bottle, Part No. 99883-88T] or a 0.35 L (12 fl oz) sprayer bottle as part of the Filter Care Service Kit (Part No. 99850-92T). K&N Air Filter Oil is also available from a Harley-Davidson dealer, either alone [347 g (12.25 oz) aerosol can, Part No. 99882-88T) or a 184 g (6.5 oz) aerosol can as part of the Filter Care Service Kit. Thank you!
