Oil is now black at oil changes. Doesn't smell burt or look gritty just black. I have been using fhram ultra filters and my oil was always a dark brown after 6000 miles but never black. Have 3 vehicles i tried theses k&n filters on and all now have black oil. Not sure if its the filter or the oil but the filter is the only thing i changed in my setup thinking i was improving things. I will not buy again going to try napa platinum filters next

Installs like a regular filter But with the nut feature on top, it's easier to remove. I believe these filters perform really well for the price.

very good for my car, i only use that from that company. My car breathes better purrs.

Such a great feature. All filters should have that.

K & N is a well known brand however at about $17.00 for just one filter is a bit much I think. If it was offered in a multi pack for $13-14 each, that would be more reasonable.

I have used these for years, when I raced boats

Quality filter, I've been using K & N filters in all of my cars and trucks over the years. Never had an issue.

The only filter I use because the nut allows easy installation and removal.
