fits my Sienna 2006 with a little adjustment - sturdy, clean and happy that I brought it
Size: 8.3" x 8.4" x 0.6"
I brought this for my Camry 2006 and I have a Sienna 2004 as well that use the same regular cabin filter with the exact model. But when I put this K&N filter on my Sienna it doesn't fit well. The K&N filter sits in the plastic cabin filter frame exactly but there are four little plastic square on the side of the plastic frame sticking out that were in the way. I trim off the K&N border a bit and also the frame too in order to fit in. Beside a little adjustment, it works perfectly for my Sienna 2004. The smell is gone. I also use an oil pen to note on the K&N filter that "Do not replace" in case the dealer replace it during a maintain. I would buy more but this is life time I will buy another one for my camry. I am more than glad introducing this to my friends

Make sure it fits your vehicle cabin filter.
Size: 8.3" x 8.4" x 0.6"
I like that it last long and I don't need to buy replacement every time a funky smell starts appearing after turning on the car or truck AC or heater. Saves money by easy to maintain without replacements.

buen material
Size: 8.3" x 8.4" x 0.6"
Es una buena compra excelente producto calza perfectamente en mi Fj cruiser 2011, en cuanto a su durabilidad lo diré cuando pueda hacerlo por lo pronto está instalado cuando haga los primeros lavados volveré a comentar si se mantienen en buen estado como promete. Lo que difiere con el original es que un lado va para abajo el que tienen una felpa tipo algodón y el otro para arriba en cambio en este filtro de cabina K&N no se sabe cual lado ba abajo o cual arriba, por eso menos una estrella

It works as advertised
Size: 8.3" x 8.4" x 0.6"
The one thing I haven't found out is if the product will remove exhaust smells - I don't believe it will, but the nice thing is that air flows a little bit better then the Toyota FJ carbon filter that was in there. I don't believe the previous owner even knew it had a cabin filter. Glad to have this in there.
