I recently installed this cabin air filter in my 2024 4Runner, and it fits perfectly. It does a great job of filtering out the dusty Las Vegas air, leaving the cabin smelling fresh. However, I did notice a slight reduction in Airflow, on the highest blower setting, it feels like the output is about 25% lower than usual. It’s still early to tell how it will perform long term, but so far, it's doing its job well. If you prioritize air quality over maximum airflow, this is a solid choice at a good price too!

Filter fits well into cabin filter compartment of 2011 Toyota Avalon Limited.

Fits easily into my cabin filter slot of my 2011 Toyota Avalon Limited. It has performed well after a month of use. The design of this filter appears to be superior to the filters that are utilized at the Toyota dealer. The filter was easy to install via the back of the glove compartment.
