Progressive Labs Methyl B12 60 tabsDescription Methyl B12 (methylcobalamin), a co enzyme form of vitamin B12, is the principal circulating form of B12 in the body and the form that is active in the central nervous system. Cyanocobalamin, the form of vitamin B12 most often used in supplements, must be converted to methylcobalamin in a lengthy and sometimes inefficient process.

Way easier to replace than I thought. I’ve done a cabin filter before, but never the engine air filter. After this, I’ll never pay someone to do it again. I actually went into a store first, and the cabin filter alone was the same price as this set that includes both the cabin and engine filters. Since I needed both, this was a no-brainer. Install was quick and straightforward, even for someone who’s not a "car guy". I can’t speak scientifically on how well they filter, but they’re definitely better than the mouse-destroyed ones that were in this car before. Huge improvement. Highly recommend if you’re looking to save money and do it yourself. They fit well and seemed to be exactly what was needed and expected.

Quality air filters

Size: For Accord 2018-2022 1.5L

The Honda dealership quoted over $100 for parts alone. I purchased both filters for $25 and they where a perfect fit and easy to install without any tools.

Solid 4 stars

Size: For Mazda 3 2019-26|CX-30 19-26|CX-50 23-26

4.5 2025 cx-50 : Cabin filter fit perfect. Engine filter was not as precise , it was a perfect edged rectangle whilst the new filter had round edges, it did fit after all. Way better than paying 100$+ at the dealer. I will come back once I notice any airflow changes & or smells .

Good Product, But Doesn't Fit All RAV4 Models

Size: For Avalon 19-22|Camry 18-24|19-25 RAV4/ES350, Size: For Avalon 19-22|Camry 18-24|19-25 RAV4/ES350

Both filters seemed to be of high quality, but the engine air filter did not fit in my 2019 RAV4 XSE Hybrid. Please note that ordering this was my mistake -- I didn't realize that the hybrid and gas-only filters were different sizes -- and that StaunchAuto also offers a hybrid version of the kit, which I have just ordered.
