Great filter!
Color: 1Pc-CA10755
Perfect fit in my 2024 Toyota Tacoma TRD Sport! My original one has 25,000 miles on it and honestly, wasn't that bad. But, I knew that if I didn't spend $20 and change it myself, the dealership guys would hound me everytime and try to sell me a $75 filter.

Great value for DIY procedure for my BMW
Color: 1Pc-CA11118
Vehicle information: 2011 BMW 535i GT F07 The fitment is perfect, installation is simple certainly a DIY maintenance procedure. BMW wanted 300$ for install. I compared my oem to this and certainly equal or greater quality so great value. The package includes a manual and a manufacturers sticker with a feedback card. It was sealed with package inside its cardboard. The filter is a beautiful vibrant red. So when it starts to collect debris you will notice I imagine because it’ll shift color but it’s recommended you repose like every 10-15k miles So intend to repurchase this exact filter when needed

Works great. Better air flow and engine power than the stock Honda air filter. Also cheaper than the OEM air filter.
