Mazda Cabin Air Filter KD45-61-J6X → KD45-61-J6X-9U delivers clean, low-resistance airflow for Mazda 3 (2014–2018), Mazda 6 (2014–2021), and CX-5 (2013–2025). Engineered to OE specifications, its dense micro-fiber media captures dust, pollen, soot, and fine particulates while maintaining HVAC efficiency and quiet operation. Rigid perimeter sealing prevents bypass leaks; a precise tab design speeds DIY installation. Optional carbon media reduces odors and NOx/ozone for city driving. Replace every 12–15 months or 15,000–20,000 km (sooner in dusty climates). Improve defogging performance, protect the evaporator, and enhance cabin comfort with a dependable, model-correct filter that fits right the first time.
