Kia Universal Air Filter

You'll want SKU12 (Kia Optima 2016-2019/1.6T/2.0T), which is engineered to fit your 2019 Optima with the 2.0T engine. We also offer SKU13 (Kia Optima 2016-2019/2.0T) as an alternative if you need a variant specific to that engine size. When ordering, please confirm your exact engine displacement to ensure the perfect fit.

SKU1 is a combo package that includes both an activated carbon air conditioning filter and an air filter, giving you two filtration upgrades in one order. All other SKUs (SKU2-SKU29) are engine air filters only, designed for specific Kia models and engine types. If you want to service both your engine intake and cabin air quality at once, SKU1 is the all-in-one choice.

Installation is straightforward and requires no modifications to your vehicle. Our direct-fit design lets you replace your existing filter in minutes by opening the air filter box, removing the old filter, and sliding in the new one—the installation guide walks you through each step, including inspecting the housing and ensuring the rubber seals align properly. Most owners complete the job without any special tools.

Yes, our high-efficiency filter media maintains optimal airflow to your engine, which supports fuel efficiency and smooth acceleration. A clean, properly fitted air filter reduces restriction on your engine's intake, allowing it to breathe more efficiently and perform at its best.

The durable construction of this filter provides reliable filtration over extended intervals between replacements, though the exact service schedule depends on your driving conditions and local air quality. We recommend checking your vehicle's owner manual for the manufacturer's recommended replacement interval, and inspecting the filter visually if you drive in dusty or high-pollen environments.
