Thanks very much for the info. Have you noticed any increased cabin noise coming from the A/C blower after changing the filters? I used exactly the same WIX filters you recommended, and I now hear the blower when the heater goes on (either with A/C on of off, and either using outdoor or recycled air). The noise is proportional to the air speed -- the more air the louder the noise.
I double-checked that both filters are properly installed.

Hey Dave,
Thanks very much for the info. Have you noticed any increased cabin noise coming from the A/C blower after changing the filters?

Any thoughts?
