I installed this AirTechnik CF12140 in my Yaris iA 2018, and it's a perfect match for the factory filter. The assembly couldn't be easier—it's a tool-free, 5-minute job located right behind the glove box. The ease of use is a major plus for anyone looking to avoid high dealership maintenance fees.
What I like most is the activated carbon layer; it noticeably neutralizes odors from exhaust and outside air much better than the standard paper filters. Despite the extra filtration, the air flow remains strong with no whistling or restriction. Pro tip: Make sure the "Air Flow" arrow on the side is pointing down when you slide it in. High quality, great price, and a fresh-smelling cabin—highly recommend!
