Great Filter!
Since I started doing long exposures , my variable ND filter of choice was Vivitar. It's worked great over the years but I was in need of a new filter.Since I also own a K&F Concept tripod, and they've treated me well, I decided to give this filter a try. What could be cooler than an ND filter and a circular polarizer in one?! And I'm glad that I did!This filter works incredibly well. With my old ND filter, I had to stack a separate circular polarizer on top which would lead to vignetting on my widest shots. With the K&F Concept 2-in-1 filter, that no longer appears to be a concern at 18mm. At 10mm, I've noticed a very slight vignetting which is almost unnoticeable. But, it's definitely a huge improvement over filter stacking.While it may require 2 hands, this filter is very easy to adjust. It also feels well built and sturdy.All in all, this filter was well worth the money invested.

2 MPG Improvement, classic K&N performance
On a 2013 Ford Escape with the 2.0 Ecoboost engine I installed this filter and made no other changes to the vehicle. Over the past month I've seen a consistent 2 mpg fuel mileage improvement in city driving. The filter is a perfect fit for the vehicle and I had no trouble installing it. I bought the K&N filter recharge kit at the same time so when the filter is ready to be cleaned I already have the stuff on hand to do it. This filter helps put a little more "eco" into the Ecoboost engine as I'm not tossing old filters into the trash any longer. And the bump in gas mileage is nice too.

In my 2011 Volkswagen Golf TDI.
Fits perfectly as a replacement air filter in my 2011 Volkswagen Golf TDI. MPG is about the same, no increase. Turbo lag seems to have diminished considerably after installing this filter.

Great Filter
I switched to this filter after using the original Mopar ones. The engine in my 97 Ram seems to run a tad smoother. I believe this filter has a less restrictive flow.

GM decided to put my Silverado pickup oil filter into the tightest possible place that no hand or standard oil filter & wrench can get into. The K&N nut on these is a savior.
