In this video, we show the step-by-step process for replacing the factory air filter on the Porsche 718 Cayman and Boxster, covering both the 2.0L and 2.5L four-cylinder engines. This is a straightforward maintenance and performance upgrade that most owners can complete in about an hour with basic tools. We walk through airbox access, filter removal, and proper installation of a BMC performance air filter, along with tips to ensure correct fitment and sealing. Compared to the OEM paper filter, the BMC filter offers improved airflow while maintaining effective filtration, making it a solid option for both stock and lightly modified 718 cars. For owners looking to optimize intake efficiency without introducing noise or drivability issues, a high-quality drop-in filter is one of the simplest upgrades available. This guide is intended to help you confidently perform the install yourself or better understand the process before having the work done. If you have questions about air filter options, service intervals, or how this upgrade fits into a broader performance plan for your 718, feel free to leave a comment or reach out. #porsche718 #porschecayman #flat6motorsports *BMC Performance Air Filter (718 Cayman / Boxster)* https://flat6motorsports.com/collecti...
