Dealer wanted to charge an insane amount of money for a cabin air intake installed so I just went around town pricing different after market brands. I know trdsparks sells them for $18ish but I found one at Advance Auto Parts for $8.49. The brand is Drive Works which is the commercial brand of Purolator and it should be a great filter. The difference is night and day for the air quality and smell coming through the vents...plus for $8.49 their is really no reason someone should not be running a cabin air filter.

 

How do you install one of these?

 

Right behind the glove box.

What was the reason again that toyota didn't put them in at the factory?

 

Install is pretty simple. Remove your lower glovebox, find the white horizonal panel to the left behind the glovebox, remove the panel, insert the filter, make sure the right side is facing up.

Because they would rather have you breathe in this crap

FYI...there is already a thread on this.
