Nice filter, a little eye candy under the hood.

Installation can be a bit confusing, but it's not difficult. Didn't notice any change with mileage as far as regular unleaded goes, but it was slightly better with premium. This is aside from the normal increase in mileage I got with premium before I installed the k&n. It's not loud, and performance feels about the same.

I installed this filter on my 2005 Ford Escape XLS 2.3 four cylinder. I combined it with&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Bosch-4459-HGR9DQP-Spark-Plug-4-Pack-of-1/dp/B000GZEKNW/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Bosch (4459) HGR9DQP Spark Plug +4, Pack of 1</a>

Though I did not get a noticeable increase in MPG, the ride does feel a bit smoother and the engine a bit stronger and slightly more responsive.

There is a small precaution you need to take into consideration though. It is common for these filters to come with a bit of excess of oil and that can affect your vehicle's AIT valve.

All in all, I personally recommend this filter.

After leaving this thing in my car for a long time unchecked it got a little dirty, but she kept on going for a long time.  The material is great, the wire mesh is strong and holds its form, and although it isn't really meant to be submerged in water (it may or may not have been and i may or may not be wearing a cowboy hat and sponge bob underpants right now) it deals pretty well with getting wet through the daily grind.  The filter recharge kits for these filter are recommended, and you can use them for years if you take care of them.  They look nice too, you might say, and yes they do, as long as you don't get an under-the-fender cold air like i put on my subaru.  The only complaint i had is they changed the inlet design and put little ribs on it to keep it from falling off, which sounds nice, but it makes it impossible to get on your piping unless you trim it a little (which takes all of five minutes). So, aside from that little issue, this is the best filter ever.  They perform slightly better than the other similar looking brand, and if thats what you truly want, its worth the extra change, and if you already own an injen intake, i wouldnt get any other filter for it.  Like ever.

I was happy to see that these are, in fact, actual, genuine SUBARU filters. Fit perfectly in my 2011 Forester. If this is your first time replacing your a/c filter (or cabin air filter, depending on which reference you look at) please know that it does involve a bit of "man-handling" to 1) get the glove box to drop down out of the way and 2) to maneuver the filter out of the blower housing. You open the glove box, pop off the glove box dampener (located on the right side on mine), then you have to force the two sides of the rear of the glove box passed the plastic that makes up the rest of the dash. The glove box uses floating hinges so it will actually come off completely without any tools. The filter itself just pulls out using four small finger tabs located on the face of the filter tray. I kind of had to twist the filter tray to the left and down to wiggle it passed the dash plastic and out of the blower housing. Installation is just the reverse of all that. Takes five minutes at most but, as I said, expect to feel like you're sort of breaking something trying to get the glove box to drop down. I'd give these filters five stars if the price was a little lower. I'm pretty sure I replaced my filter this time last year so, as you can see in the photo, it's certainly a good idea to stick to the manufacturer's recommendation on this one.

A bit annoying to install, but not the products issue.  Fit properly and after watching a few videos had it installed in maybe 30min.  Can;t really tell any difference, but the filter I replaced was completely dirty.

Work super well as an additional filter. I think the inner components can be arranged better to maximize filtering capacity.

I do like the fact that you can screw the filters into each other to customize the amount of macro that you get, but there's a very small window of clarity in the pictures that you take due to a blurred fish eyed effect around the outside that takes up most of the image.

This is an excellent Filter.  Yeah, it's pricy, but it's one of those things that you get what you pay for, and I enjoy my camera and my lens to much to trust it to the lower end of the spectrum when it comes to filters.  Go With It!

Decent filter, only thing they only have the 52mm size but no markings to identify the manometers.  Would not have been that much more effort to add 690nm, 1000nm, ect... on filter. My other filter was also like that so 4 stars. Also I have a 950nm filter, with a full spectrum cam the 950 is much darker then the 1000nm... maybe the 950 I have is better at blocking viable light then this 1000nm. But gives nice b&w look.

Slightly small/loose fit, but great filters!  I have used several of these, they seem to trap more dust and debris than other filters I have used. They do have a slightly smaller fit, in fact if the filter slides off center it may not completely seal the opening. I resolve that easily by placing some small black magnets around the filter housing to keep the filters centered. Now they work great, Im extremely happy.

The filters are great, while the lens hood is hard to unthread off a filter, due to it being made of plastic, which deforms.

A great little set of filters to allow experimentation with ND photography and avoid those "blown out" skies on very bright days.
I take off a star though as the threads are a little tight and could have been machined better.

Upon unboxing and holding this cabin filter in my hand, I was impressed by the build quality. It most definitely has some heft to it compared to the stock Toyota filter and the Fram brand I've used before. More pleats and it fits snugly in my 2009 Rav4. A nice perk is that you don't need to worry about air direction.
As for how well it works, I can't say it's better or worse than any other cabin filter yet as I've only had this for a little over a month. Some variables also are how well your door gaskets are in keeping out exterior odors. So far it has been working well while I sit in traffic with the AC on behind trucks or cars with exhaust issues. The air flow coming in through my vent doesn't feel any worse, about the same considering how thick the filter seems to be. I have noticed a slight hint of coconut or something similar, no offending scent from this cabin filter. Just might pick up another one for my Civic to see how my better half likes it.

Ran over the filter that came with my cold air intake. Couldnt find a replacement at any local parts store or any parts store in a fifty mile radius. Took a chance and ordered this one. Decent quality for a brand I never heard of. Bit of a pain to install but I got it on there. Only took a six pack and a pack of smokes to do it. Anyway, would give it five stars if it wasn't for the installation difficulty. Its a little too precise on the diameter so use a flathead screw driver to pry it on.

Awsome filter, oil stays clean just fine. Filter is a tad bit bigger than aftermarket, I love that.

Perfect fit could be built a little better the filter spins inside the housing but can be fixed with some adhesive
