 Simply the best air filters this world has to offer. I've put K&N Filters in everything I've ever owned that had an engine and they made a filter for it. Wish more companies built things to last most people's life time instead of the planned obsolesence path.

 I look forward to getting this installed in my 2010 gl1800. Had one on my other Goldwing. Worked out great & the hat was nice also.

 One nice thing I like about your product is you can go 50,000 miles without cleaning it which is very difficult to replace the filter on the Honda Goldwing. Go on YouTube and see how difficult it is. I also have them on all 3 of my vehicles. Thank you.
