Honda Air Filter 17220-PZA-000 / -505 – Honda Civic (2003–2005, later replaced by -505) delivers a precise, OE-grade seal and high-surface-area media to trap dust and pollen while maintaining strong intake flow. The result is steadier idle, sharper throttle response, and protected MAF/throttle components on aging D-series platforms. Moisture-stable frames resist warping across heat cycles; rattle-free geometry helps reduce induction noise. Drop-in dimensions make DIY service fast—no special tools required. Replace at factory intervals, or sooner in dusty climates, to preserve fuel economy and keep emissions systems happy. For the superseded “-505” reference, expect identical fit with incremental media and durability refinements.
