Review on 🔍 K&N Engine Air Filter: High Performance, Washable Replacement Filter for Toyota/Lexus (Kluger, Highlander, Camry Hybrid, Sienna, Alphard, Solara, Wisdom, ES/RX 300) 2001-2014, Model:33-2260 by Kenneth Witte

Not sure about other people's complaints about the ease of installation. Installing it on my 2012 Highlander took just five minutes. However, they must be installed in EXACTLY the correct orientation or the ribs on the airbox will not fit into the grooves on the filter. This can lead to difficulty closing the air chamber. If you carefully orient the filter in the right direction, it should be snug and the airbox will definitely close without too much effort. This is a very high quality reusable filter. Highly recommended.
