My prius just turned 20K and I was changing the engine air and cabin filter. I got both toyota brand filters from the dealer when I bought the car. The new engine air filter looked like what was in there. But the cabin filter was completely different. There was far fewer pleats in the filter and the pleats that were there you could see though. It looked like the pleats would rip of they were touched. Did toyota change there cabin filter design to allow more air flow but less filtration ? Is there an upscale filter that comes with the car, but unless you ask for it, you get this cheap one ? If this is what toyota is selling now, does anyone have a recommendation for a good quality cabin filter ? Thanks for any help.
