Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-812. 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 2017 Audi Q7 and interchanges with OE part 4M0 254 200 NX. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Broken after 6 weeks of use
Color: White
Bought this so I didn’t have to heat my milk before frothing. No longer heated after 6 weeks. Too late to return. I consider this a bad buy. Wound up in the landfill.

Works great and easy to use
Color: Black
I feel like I’ve finally found a decent milk frother! I’ve gone through (or returned) several models over the last few years, but this one has a different design and hasn’t frustrated me like the others. It has plenty of power to froth milk, foam quality is good, heating is good. I checked the temperature a few times, since a few reviews were critical of that, and it was within a degree or two of what I’d set, so I’d say it’s good! I appreciate that it remembers the last settings so most days are a 1-click operation. But even changing the settings is easy - easier than others I’ve used while having more options.

Best addition to our coffee bar
Color: Black
BEST milk frother we've owned. It is on the larger size but worth it. I love that there are multiple temperature settings. It is easy to use and figure out. The frother spins inside of the stainless steel cup and is magnetically attached inside so it does not come off easily. We use agave for sweetener and being able to throw the cup into the dishwasher to clean off residue has been the biggest plus of this frother. Highly recommend. Worth the cost.
