There isn’t a single universal air filter part number for every 2006 Civic. The correct number depends on the car’s engine and trim. In this model year, most Civics used a 1.7-liter D-series engine, while the high-performance Si used a 2.0-liter K-series engine, and each engine can have a different OEM part number. To get the exact number, identify your engine code and consult a parts catalog or the filter housing label.
Understanding the 2006 Civic’s engine options
Two main engine configurations were common in the 2006 Civic lineup. The 1.7-liter inline-four (D-series) powered most DX/LX/EX models, while the 2.0-liter inline-four (K-series) was used in the Si. Each engine uses a distinct air filter compliance and part number, so the correct part depends on which engine your car has.
2006 Honda Civic with the 1.7-liter D-series
The majority of non-Si Civics from this year use the 1.7-liter D-series, which requires a specific air-filter element sized for that engine. The exact Honda OEM part number is assigned to this engine configuration and can vary by revision, region, or supplier, making a VIN-based lookup the most reliable method to confirm the correct part.
2006 Honda Civic Si with the 2.0-liter K-series
The Civic Si uses a larger, higher-performance 2.0-liter K-series engine and, correspondingly, a different air-filter part. Because this engine differs from the D-series in fit and specification, its OEM part number will differ from the 1.7-liter models and should be verified via engine code or VIN.
How to determine the exact air-filter part number for your car
Use the following steps to confirm the precise part number for your 2006 Civic, regardless of trim or engine:
- Check the old air filter or its packaging for a part number printed on the filter itself.
- Inspect the air-filter housing label or stamping, which often includes the OEM part number or a cross-reference.
- Find the engine code (for example, D-series or K-series) on the engine block or service stickers under the hood.
- Use the vehicle’s VIN to search Honda’s official parts catalog or a reputable parts retailer’s lookup tool to pull the exact match.
- Consult the owner's manual or a factory service manual for the correct replacement part for your exact model and year.
These steps help ensure you buy the correct filter for your engine, even when multiple Civics from the same year use different part numbers.
Where to verify and cross-reference part numbers
Cross-referencing can confirm you’re ordering the right part and can help you find compatible aftermarket options if needed. Use these methods:
- Enter your VIN in Honda’s official parts catalog or a trusted dealer portal to reveal the exact OEM air-filter part number.
- Check reputable auto parts retailers’ catalogs, which will list the OEM number and common cross-references (Wix, Fram, Bosch, etc.).
- Compare the air-filter dimensions and fit with the housing opening and mounting points to ensure compatibility.
- Ask a parts counter associate at a Honda dealership to confirm the correct number for your engine code and production date.
By validating with VIN-based catalogs and cross-referencing reputable sources, you can be confident you’ve selected the correct air-filter part for your 2006 Civic.
Summary
The 2006 Honda Civic does not have a single universal air-filter part number. The correct number depends on whether your car uses the 1.7-liter D-series or the 2.0-liter K-series engine, and even within a given engine, revisions and regional differences can apply. To obtain the precise part number, identify your engine code or use the VIN to lookup the exact OEM part in Honda’s catalog or a trusted parts retailer. This approach ensures you order the right filter and achieve a proper fit and performance.
