      I bought research for my nissan titan and they are great, the old ones looked like the inside of a vacuum cleaner bag, nasty! So I figured I would get some for my 2003 gmc sierra as well. Guess what? 2003 doesn't have them. So just make sure you can get to your filters before you order, I know for sure 2003 gmcs DO NOT HAVE THEM

      The filter fit my 2002 996T as described. It has been used now for a month. It took away that slight musty smell from an old filter that was dirty. Glad I changed it. It is made in China like everything is these days but the quality and feel were very similar to the original I pulled out. It fit just fine and was very easy to install. Takes about 5min. Will buy again once I need another one.

      This ended up being bigger (thicker) than the OEM Volvo filter that I pulled out. I almost sent it back, thinking it was the wrong part. But once I got the orientation correct, it slid right into place. Make sure you pay attention to the way the old filter comes out. There's a plastic part that, if I recall correctly, should slant up to the left on the top of the filter when you're holding it and facing toward the front of the car.I found the easiest way (with the most room to work) was to remove the carpet mat and the air filter cover (after removing the main cover under the glove box).All in all, it was very easy to install. Maybe 10 mins, including some initial frustration with the size. Remove a plastic panel by loosening a plastic fastener by the passenger seat (helps to move the seat all the way back). Then unscrew the two Torx screws attaching the panel below the glove compartment. Then remove the smaller screws that hold on the actual filter...

      The is the same product that I have purchased before and I am staisfied with its performance just like the OEM. And I think Mazda uses this brand as their OEM since there is no differences when visually inspected.

      Arrived quickly and did what it should do. A marvelous filter. Installed quickly and easily. Was a treat to breathe the freshly filtered air.

      This filter is just like the factory original. It fit perfectly. It works fine, and is less than half the price of the filter from the local auto parts store.

      Much less expensive than the dealer cost for the in cabin air filter. Fit is perfect, just like the factory equipment.

      Easy to replace in my 2000 Volkswagen EuroVan Camper. Pop the hood open, remove the 3 snap locks, separate the old filter from the holder, slide and twist this new one in and work your way backwards. This filter actually arrived in San Diego in less than a week!

      Not even the A/C specialist I work with knew about this second pair of interior cabin air filters for the recirculate air function of the climate control system. The pair of large fresh air intake filters on the hood are commonly replaced for the dirt and leaves/twigs they capture, but the inner cabin filters capture the finest, nastiest dust imaginable. I just bought a well-maintained 1998 740i, and the inner filters were clogged with what looked like powdered graphite. Of course, for both outer and inner, opt for the activated charcoal filter elements, as opposed to plain paper - the cost is justified.

      I started replacing my own filters last year. My 2007 Forester was a bit tricky due to all the screws in the glove compartment ( you always miss one!) Since then they have made an improvement and my 2011 doesn't require screws to be taken out. You just take off the hinge and pop out the glovebox. It is a bit scary popping out the glovebox since it takes a bit of force to do it. I was afraid of breaking something but I have replaced my filter twice and so far so good. This saved me around $100 in labor at the dealer!

      This is working perfectly in my volvo XC90 2006. My husband installed it a couple months. Great price too, way less than ordering from the Volvo dealership and the hassle of taking it there to change. There is no smell and the air seems fresh. Don't be nervous about off brands, just buy it.

      I have looked all over for replacement cabin filters for my BMW 530i. In the past, people (including BMW enthusiast sites) would send me the thin, flimsy cardboard-lined filters that always seemed cheap, poor fitting, and ineffective.The filters I've purchased from AutoPartsWAY have the OEM rubbery/plastic surround and fit beautifully!I'm a very satified customer and will purchase these from AutoPartsWAY for as long as I keep my vehicle.

      This was an easy DIY part that costs a faction of what the car "stealership" would charge you! Took me less than five minutes to install.

      Easy to install. Will not work on some Silverados. I have a 2001, works for me. My Son has a 2002, same heater, but the filter chamber has been covered over.

      Ever try to find the in-cabin air filter for your car at your local car parts store?Just order it through AutoPartsWAY.com and it shows up at your door a few days later - is there any other way to buy?Installation can be a little tricky, but it's worth it instead of giving your car dealer $80 to do it.

      They fit. Why pay twice the price for something as simple as this. They are not super deluxe but do what they are suppose to do. I change mine every 10K miles.

      Will purchase this filter again. I know I saved $10+ over other vendors. It takes 2 minutes to replace in my Toyota Highlander.

      It took less than a minute from start to finish to replace the cabin air filter. Slid right in, no problem.

      5 stars. The shipment came 3 days eariler. Exactly like my offical BME 745 Li filter. But remember to order 2. The serial number within the description may lead one to think it say 2 per car.

      Fits my 1996 Volvo GLE like the factory made stuff, only it costs 1/3 the price, fits perfectly into the clips and everything and so far I am not smelling any gas exhaust from cars in front of me. Great product, unlike the junk I bought from Bosch!!

      15 Mar, 2012
      The product is just fine, but know what you're getting into. I have a 2007 Nissan Altima 2.5S and I had to pull my glove box out of the dash to install the filter. Do yourself a favor if you're going to do this and look up videos on youtube so that you know what you're getting into.

      This is a perfect fit and exact OEM part. The ones from Fram, STP and others at the car parts store, do not fit and leave a gap that will cause motor problems. I have a 1998 528i and this is a perfect and exact fit. I ordered mine from AutopartsWAY and they were super fast! Why pay $80 each at the dealer? Get them here. I'm a fan!

      This filter did not fit my 2007 Lexus,Ls 460. This filter was for the Ls 460 L model and was for the rear cabin rather than the front cabin. Correct front cabin filter is smaller than the rear filter. The return procedure was easy and I received a check for a refund,minus shipping costs, within days.

      So, yeah, it filters. Seemed a little flimsy going in, but heah filtering nicely, so no complaints. Definitely cheaper (in price) than what they had at the store. The cheapest I could find there was $40, so very good deal.

      Arrived as promised, on time and well packaged. Instructions said it would take about 15 minutes to change, but it only took about 2 on the Scion xa. Doesn`t seem to restrict air flow. Makes a difference on high pollen, dusty days.

      Replaced old cabin air filter in Jaguar 04 X-Type with this. Fits fine. Appears to be less dense/cheaper then the oem filter. When I tested the air conditioner I found it actually blew much much harder and I would attribute that to this filter being less dense hence easier to pull more air through.If you want a cheap filter this works fine but I think next time I might invest a little more in a higher quality charcoal type filter

      At a fraction of the dealer's price, this filter is perfect for my 2004 V70 2.5T Volvo. Installation is somewhat easy with the instructions that can be found on the web.

      1998 Honda Accord EX/V6 Automatic: I am glad I made a choice to do most DIY. After 140K I don't think any dealership nor mechanic shop bothered to replace this filter even if I asked them to do the required maintenance on my car. The filter location is very inaccessible but it's worth replacing it. The filter seems to be the OEM exact replacement and fit. I needed 2 of this Pollen Filter for my Honda Accord.

      Thank you for the quick shipping. It helps if you're a gymnast when you install this. That would be the case with any brand filter. The under dash location in the Mini is tight.

      It is about the same size as the original but it does feel a little longer. Not hard to install either. So far air quality is nice but need to test more to give it a full 5 star.

      This fit the bill and cost much less than buying on Maui. Easy install when the never-changed filter on my 1998 Volvo was completely clogged and uncleanable.

      Ordering online saved me TIME and $$$. Ordered on blind faith b/c there's no image. But this is a prefect fit for my '99 RX 300. Dont see a difference between this filter and the bosch i had.
