Review on TYC 800008P vs. 800008C: 🔍 Which Cabin Air Filter is More Effective? by Steven Ferguson

They fit and work well in my Toyota Sienna. I bought them at the same time as the fan motor resistor. Thought since I was in the area it would be wise to go ahead and change the filters. Turns out my van never had cabin air filters. There were spaces for filters, but there were no filters. So all those years, pollen and who knows what else got into the cabin through the ventilation system. When I installed them I noticed a slight reduction in airflow. But that's to be expected when you put an obstacle where none was before.
