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
