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
