Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-439. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed specifically for the 2010-2012 Mercedes-Benz GLK350 and interchanges with OE part 204 490 34 20. Hardware is included to eliminate the hassle of working with corroded factory parts.

Won't be returning this one, will actually buy it for the rest of my cars! ⭐️⭐️⭐️⭐️⭐️

Female with no knowledge about cars seal of approval!
Size: For Mazda 3 14-18 2.0L/2.5L|Mazda 6 14-21 2.5L
Perfect for my 2016 Mazda3. I am a young female with zero tools and zero knowledge about cars. My dealer was asking over $60 to change these out, and after a 5-minute course at YouTube University, I was able to do everything myself in under 15 minutes. It’s my crowning achievement of 2026. I recommend gloves when you go to change out the engine and make sure it’s wiped out and cleaned before you put the new one in! But other than that, it’s honestly just popping a few things out, changing the filters, and then popping them back into place. They look almost identical to the filters that were already in there. There was no wrestling with making them fit because they just slid easily into place. Great buy and unbeatable price if you have a few minutes to spare to do it yourself!

Easy Install - Looks like the Original
Size: For Ascent 19-26|Crosstrek 2.0L 18-22/2.5L 21-22
Both of these filters, cabin and engine are really easy to install at home with NO tools needed and at a fraction of the price that dealers charge. These filters are for a Subaru Impreza and look almost identical to the originals and fit perfectly. Cabin filter installation is by dropping the glove box - detach damper rod and unclip sides. Unclip filter cover behind glove box and remove/replace filter checking airflow direction is the same as the old filter. Reinsert glove box and push up to locate side clips. Re-affix damper rod and you're done. Engine filter is equally easy. Unclip air filter housing (not necessary to remove entirely) slide out old filter and insert new on in same orientation. Re-attach clips and done. Took me 10 minutes to change both filters. Longest part was emptying all the cr*p out of my glove box. Good quality filter, easy to install and saves time and money. I bought a second set for a Mazda CX-5 non turbo and quality was the same. Installation exactly the same as above for the Subaru
