Great purchase
Used K&N oil and it is working like a K&N air filter. Getting better gas mileage and crisper throttle response. Good pricing and quality.

Good Air filter
I have gotten K&N exclusively in the past, but this had the same projected lifespan and stuff. So I bought it and I believe it to be equal in quality at a better price than the competition

great air filter for a great price
I needed to replace the factory filter in my GPz900 and I read that this was just as good as a K&N but half the price so I had to try it out. I haven't gotten much of a chance to ride the bike but I'm confident this filter works great. I would recommend it.

Outstanding
Fit was perfect. Great value for the money. I will actually save money over the year if I would follow the replacement schedule on oem filters. I like being able to clean, lube and reinstall this filter. Shipping was much faster than I expected.

Good Alternative
I hate to throw money away. This is a low cost alternative to other lifetime filters and it fit into my airbox very well.
