Frequently Asked Questions
What size hose does this breather use?
3/8" diameter hose. Verify your bike's stock breather hose size before ordering.
Can I replace just the filter element?
Yes. Harddrive sells replacement filter elements separately so you don't need to buy the whole assembly again.
Is this a direct bolt-on?
Yes — this is a direct replacement for stock crankcase breather systems on V-twin motors.
Why do I need a crankcase breather filter?
The filter separates oil mist and moisture from crankcase vapors, preventing oil from entering your air intake and keeping the engine cleaner.

Having no luck with the harley shops around here it was a pleasure getting them thru you. The main reason I was given, that they could not get them, always on back order. Thank you for being so helpful. <br /> MUTT Duncan

These things are very well built, nice pieces, but huge. I was looking for a small filter for crank pressure bypass but these are simply too large to mount anywhere.
