OK, by time I'm due to replace the cabin air filter and the engine air filter on my 2018 Prius Prime. Should I also be looking at the hybrid battery air filter by the back seat? (I probably at least should vacuum it.) Looking at videos online the filter replacements still look as easy to DIY as my older Prius were. AC cabin filter behind the glove box, and engine air filter just a few clips to the box cover. I prefer to use an OEM filter, but recall back in my Yahoo groups days with my previous Prius that there were a few trustworthy dealerships that I could order OEM parts from, that after shipping would still be less than from my local stealership. Are there still a few good dealership parts departments around that offer similar decent pricing and customer service?
