For a 2018 Honda Accord, the price you pay depends on whether you need an engine air filter or a cabin air filter. Engine air filters generally run about $10–60 for aftermarket or OEM parts; cabin air filters usually cost about $15–60. Labor and installation, if you have a shop do it, can add to the total.
Filter options and current price ranges
The 2018 Accord uses two common types of air filters. Understanding the difference helps you budget and decide where to buy.
Engine air filter prices
The following list outlines typical price ranges you’ll encounter when shopping for the engine air filter separately from the car’s HVAC system.
- Aftermarket engine air filter: typically $10–$25
- OEM Honda engine air filter: typically $25–$60
Engine air filters vary by brand and material (paper, oiled paper, or performance media). If you opt for OEM parts, you’ll likely pay toward the higher end of the range, but this can ensure exact fit and filtration performance.
Cabin air filter prices
The following list covers the most common pricing you’ll see for the cabin (HVAC) air filter, which helps keep the interior air clean and free of odors.
- Aftermarket cabin air filter: typically $15–$40
- OEM Honda cabin air filter: typically $25–$60
Cabin filters often have multiple media options (standard, activated carbon, or odor-absorbing variants), which can push price upward, especially for OEM or carbon-activated versions.
Where to buy and installation considerations
Prices can vary by retailer and whether you want the convenience of online ordering or the assurance of in-person help. Consider these common buying channels and what to expect in terms of installation.
- Dealership (Honda dealership): typically higher prices, but guaranteed fit and availability of OEM parts
- Auto parts chains (oō AutoZone, Advance Auto Parts, O'Reilly): broad aftermarket options with frequent promotions
- Online retailers (Amazon, RockAuto, manufacturer websites): often competitive pricing and wide selection; verify compatibility with your VIN or engine option
If you’re having a shop replace the filter, you’ll also see labor charges added. Cabin filter changes are usually quick and inexpensive, while engine filter replacement may involve slightly more labor. Always ask for a price estimate that separates parts and labor.
Maintenance notes and quick tips
Regularly checking and replacing both filters helps maintain engine efficiency and interior air quality. Common maintenance guidelines are:
- Engine air filter: typically inspected during routine service every 15,000–30,000 miles, depending on driving conditions
- Cabin air filter: often recommended every 15,000–30,000 miles in normal conditions; more frequent changes may be needed in dusty environments
- Signs you need replacement sooner: reduced airflow from the HVAC system, noticeable engine misfires or reduced performance, or foul interior odors
Prices and availability can vary by region and time, so it’s wise to compare several sources before purchasing.
Summary
For a 2018 Honda Accord, plan for two filter types: engine and cabin. Engine air filters generally cost about $10–60, while cabin air filters run about $15–60, with OEM parts tending toward the higher end of the range. Shopping at dealerships tends to be pricier but ensures exact OEM fit, while aftermarket or online retailers often offer lower prices. If you factor in installation, total costs can vary further depending on labor charges. Regular replacement helps protect your engine performance and cabin air quality.
