The K&N 57-series FIPK intake for Toyota 4Runner V6 4.0L (2015–2019) pairs a washable, reusable high-flow filter with a CAD-designed intake tube for a direct-fit upgrade. Legal in all 50 states, the system drops into the factory airbox and can extend service intervals, while typical installs take under 90 minutes with standard hand tools and K&N warranty coverage.
