Review on K&N Engine Air Filter: High Performance, Premium, Washable, Replacement Filter for Toyota/Lexus/Mitsubishi 🔧 (Highlander, RAV4, Sienna, Avalon, Camry, ES 350, NX300, Rx350, L200, Triton) 2010-2019, Part Number 33-2443 by Jack Robi

The mileage hasn't really increased, but that's because of all the other driving-related variables. Load weight, number of passengers, type of gas and above all driving style. My highs reach about 24 miles per hour. But I will say my lows went from about 14mph to about 16mph. The main advantage is that it costs about the same as buying a Toyota OEM filter. But you only buy it once instead of every other oil change. The filter cleaning sets have lasted about 2 years even with regular cleaning. It's very worth it.
