Cabin Engine Air Filter Kit for Elantra 2017 2018 2019 2020

COCOAUTO's 2-in-1 air filter kit replaces both the cabin and engine filters to restore airflow, reduce interior odors, and protect your Elantra-series vehicle's performance.

Designed for Hyundai Elantra (2017–2020), Forte (2019–2024), and Elantra GT (2018–2020) models, this kit bundles an activated carbon cabin filter with a high-flow engine air filter so you can perform routine maintenance with a single purchase. Each filter is manufactured to near-OEM fit and finish to make installation straightforward and to match factory dimensions. The set includes common OEM replacement numbers so you can confirm fitment before ordering and avoid unnecessary returns.

How will this kit affect my car's interior air and odors?

The included activated carbon cabin filter helps capture particles and reduces common odors entering the passenger compartment. It won’t cure mechanical smells, but it significantly improves perceived cabin air quality when compared to a clogged or original-fitted filter.

• Activated carbon layer reduces smoke, exhaust, and mild odor penetration.
• Traps dust, pollen, and road grime for cleaner vent airflow.
• Matches OEM dimensions for proper sealing and fit inside the HVAC housing.

Will the engine air filter improve performance or fuel economy?

The high-flow engine filter in this kit restores designed intake airflow that a dirty filter restricts. While it won’t transform power, a clean filter helps maintain stable idle, consistent throttle response, and the fuel economy your vehicle was built to deliver.

• High-flow media reduces intake restriction compared to clogged filters.
• Helps prevent debris from reaching the engine air box and MAF sensor.
• Easy to replace in about 10 minutes; follow recommended service intervals.

How often should I replace these filters and how do I verify fit?

COCOAUTO recommends replacing the cabin and engine filters every 12 months or every 12,000 miles under normal conditions. If you drive in dusty, urban, or pollen-heavy environments, check and replace filters more frequently. Before purchasing, confirm compatibility using vehicle-specific fitment references or tools to ensure you order the correct kit.

• Standard replacement interval: 12 months / 12,000 miles.
• Shorten interval for dusty roads, heavy pollution, or frequent off-road use.
• Cross-reference OEM numbers (listed below) or use your online vehicle lookup tool.

What does the kit include and how long does installation take?

This two-piece kit contains one activated carbon cabin air filter and one high-flow engine air filter packaged together for convenience. Both filters are designed so most owners can complete replacement in roughly 10 minutes without special tools, making routine upkeep fast and cost-effective.
