ITESIER Cabin Air Filter Kit for 2012–2019 Mercedes GLE/GL/ML/GLS — 3-Piece OE Replacement with Charcoal + Particulate

ITESIER Cabin Air Filter Kit restores clean, odor-reducing airflow for compatible 2012–2019 Mercedes GLE, GL, ML and GLS models by replacing OEM parts 1668300318 and 1668300218.

If your Mercedes is due for a cabin air filter change, this three-piece ITESIER kit supplies both the under-hood particulate filter and the two charcoal recirculation filters located behind the glove box. Designed to match the fit and function of the original equipment numbers listed, the kit addresses dust, road debris and many common odors that travel into the passenger compartment. The package is tailored to a wide range of Mercedes SUVs around model years 2012–2019 so you can replace all required filters in one order and get back to driving with clearer airflow.

What’s included in the three-piece kit and why each part matters?

The kit bundles two charcoal media filters for cabin air recirculation with one particulate media filter for incoming fresh air. This combination addresses both solid particles and many common odors, giving fuller coverage than a single filter replacement.

• Two charcoal (active carbon) filters: installed behind the glove box to reduce smells and gaseous contaminants during recirculation.
• One particulate under-hood filter: captures dust, pollen and larger airborne debris drawn from outside.
• OEM-equivalent fit: labeled to replace part numbers 1668300318 and 1668300218 for direct swap-in.

How easy is installation and what tools do I need?

Installation is straightforward for a DIYer comfortable with basic vehicle maintenance. The charcoal filters are accessible from behind the glove box; the under-hood filter sits in its housing and can be changed without specialized tools.

• Typical time: about 10–30 minutes depending on model and experience.
• Tools: usually a screwdriver or basic trim tool; sometimes no tools required for glove box panels.
• Instructions: follow vehicle service manual or a model-specific guide for proper filter orientation and housing clips.

Will these filters affect cabin air quality or HVAC performance?

Replacing worn filters with fresh media helps maintain proper airflow and keeps the HVAC system working efficiently. While not a substitute for professional cleaning of the ventilation system, fresh filters reduce particle load and common odors entering the cabin.

• Improves particle capture compared with clogged filters, supporting consistent airflow.
• Charcoal media reduces many odors from outside sources and vehicle interior recirculation.
• OEM part number compatibility ensures correct fit and secure sealing in filter housings.

Who is this kit for: drivers and technicians who own the listed Mercedes GLE, GL, ML or GLS models from 2012–2019 and want a single, OEM-equivalent replacement package for both cabin recirculation and under-hood intake filters. It’s also suitable for fleet maintainers and DIY enthusiasts seeking time and cost savings by ordering all required filters together instead of buying pieces separately.
