Breathe clean air with a fresh Cabin Air Filter in your 2020 Chevy/GMC 3.0L Duramax. Shop now at XDP and ensure your HVAC system is properly operating with a new cabin filter! Found on many newer vehicles, these filters should be replaced regularly to avoid allergen and debris buildup, and to also ensure there is no extra restriction in the HVAC system. Cabin Filters install inside the vehicle HVAC ducting and help remove pollen, dirt, dust, and outside contaminants before it is circulated through the passenger compartment. In most cases the cabin air filter is easily accessed inside the vehicle interior or under the hood.
