Detailed Product Overview

The Bosch 6088C cabin air filter uses a high-efficiency particulate design to capture fine airborne contaminants before they enter the passenger compartment. Its filter media combines spunbound polyester with synthetic meltblown fibers to support efficient airflow while trapping allergens, dust, and other particulates. This makes it a practical choice for daily driving in urban traffic, seasonal pollen conditions, and environments with elevated airborne debris. The Bosch HEPA Premium Cabin Air Filters line is engineered around strict filtration standards, and 6088C reflects that focus in a direct replacement format for select Kia and Hyundai models.

This part number, 6088C, is a fitment-specific cabin filter for 2016-2020 Kia Optima, 2016-2019 Hyundai Sonata, and 2020 Kia Cadenza applications. If you are searching for a Bosch 6088C cabin air filter for Kia Optima or Hyundai Sonata, this part is built for those vehicle platforms.

What It Helps Address

• Dust entering the cabin through the HVAC system

Installation Notes

Replace the cabin air filter according to the vehicle service schedule or sooner if airflow drops, odors increase, or the filter shows visible contamination. Confirm the vehicle year, make, and model before installation. Bosch 6088C is an OEM-standard cabin filter, so it is intended to install in the factory filter location for the listed applications. No activated carbon pre-filter is included in this design.
