Engine air filters for a 2018 Honda Civic typically cost about $7–$40, depending on brand and whether you choose an aftermarket or OEM part. Cabin air filters usually run about $15–$40. If you have a shop replace either filter, labor adds roughly $20–$100, depending on location and labor rates.
To understand the question fully, you need to specify which filter you’re buying—engine air filter or cabin air filter—and whether you’re purchasing OEM or aftermarket components. This article breaks down typical price ranges and what affects them for the 2018 Civic, including DIY replacement versus professional service.
Engine air filter price
Prices vary by brand, retailer, and whether you choose OEM Honda or aftermarket. The ranges below reflect common options found in North American auto parts stores as of 2024–2026.
- Aftermarket engine air filter: typically $7–$25
- OEM Honda engine air filter: typically $25–$40
- Premium/high-performance or specialty filters: around $30–$50
In practice, many Civic owners opt for a reputable aftermarket filter to save money, while others choose OEM for guaranteed fit and warranty considerations. Engine air filters are generally straightforward to replace at home with basic tools.
Cabin air filter price

- Aftermarket cabin air filter: $15–$30
- OEM Honda cabin air filter: $25–$40
- Premium/HEPA or carbon cabin filters: $35–$60
Cabin filters are commonly replaced during routine maintenance and are easy to DIY. Pricing reflects filtration level and brand reputation, with carbon or HEPA variants costing more.
Labor and total costs
If you hire a shop, labor and service fees add to the parts price. Below are typical scenarios and ranges to help you estimate total cost.
- DIY replacement: pay only for the filter(s) themselves (engine: $7–$40; cabin: $15–$60)
- Professional replacement (engine air filter): total typically $40–$90, depending on labor rate and parts
- Professional replacement (cabin air filter): total typically $30–$70
For maximum savings, many owners replace filters themselves when comfortable with the process, which avoids labor charges entirely. Prices can vary by region and shop, so check local quotes for the most accurate figures.
Where to buy and how to save
You can source filters from auto parts chains, Honda dealerships, or online retailers. To save money while ensuring proper fit for your 2018 Civic, compare prices across retailers, verify compatibility with your exact model and engine, and consider loyalty programs or bulk purchases. Reading user reviews can help gauge long-term reliability of aftermarket options.
Shopping tips to save money include checking for coupons, looking for bundled deals (engine and cabin filters purchased together), and ensuring a return policy in case the filter doesn’t fit your vehicle. Always confirm the filter orientation and installation instructions before replacing.
Summary
For a 2018 Honda Civic, engine air filters typically cost $7–$40 and cabin air filters $15–$40, with higher-end options reaching $50 for engines and up to $60 for cabin filters. DIY replacements mainly involve the cost of the filter itself, while professional service adds labor—often making total costs in the $40–$90 range for engine filter jobs and $30–$70 for cabin filter jobs. The exact price depends on brand (OEM vs aftermarket), retailer, and regional labor rates. Checking the owner's manual for recommended replacement intervals (usually roughly every 15,000–30,000 miles for the engine filter and 15,000–25,000 miles for the cabin filter, depending on driving conditions) can help you plan and budget accordingly.
