The 2006 Dodge Caravan uses a standard spin-on oil filter, but the exact part number depends on the engine installed. Most early- to mid-2006 Caravans used either the 3.3-liter V6 or the 3.8-liter V6; both take a conventional replaceable oil filter. To be sure, verify your engine type via the VIN or the current filter markings.
Engine options and filter compatibility
Because the Caravan's engine choice affects the correct filter, it's important to identify which engine you have before buying a replacement. Below are the two common options and how to identify their filters.
3.3L V6
The 3.3L V6 version uses a standard spin-on oil filter that is widely covered by aftermarket and OEM cross-references. The exact Mopar factory filter number varies by production date, but most common cross references from Wix, Mann, Bosch, Purolator, and Fram will fit this engine when used with the same thread size and gasket diameter. To ensure accuracy, compare the filter you remove with the replacement or check the vehicle’s service manual.
Before you choose a replacement, confirm the engine by one of the following methods.
- Check the engine code or stamping under the hood for "3.3L" or related engine family codes.
- Look at the current oil filter for any part numbers or branding.
- Consult the owner's manual or service documentation for the exact Mopar part number.
- Ask a parts specialist with your vehicle's VIN to pull the correct cross-reference.
These steps will help ensure you purchase the correct filter for the 3.3L engine.
3.8L V6
The 3.8L V6 also uses a conventional spin-on oil filter, with compatibility across standard aftermarket brands that match the thread size and gasket type used on Chrysler 3.8L engines. As with the 3.3L, the exact OEM part number is best confirmed via VIN or the existing filter's markings.
Before you choose a replacement, confirm the engine by one of the following methods (same list as above).
- Check the engine code or stamping under the hood for the 3.8L designation.
- Inspect the current filter for a visible part number.
- Use the VIN/parts database to pull the proper Mopar cross-reference.
- Consult the retailer with your VIN to ensure compatibility.
Following these steps will help you select the correct filter for the 3.8L engine as well.
What to buy and how to verify
When shopping, you’ll see two main options: a traditional Mopar OEM filter or a reputable aftermarket replacement that matches the engine’s thread size and gasket. Most brands list compatibility for Chrysler/Dodge minivans with 3.3L and 3.8L V6 engines. Always verify the replacement’s compatibility against your vehicle’s year, make, model, and engine code.
- OEM vs aftermarket—OEM (Mopar) filters guarantee exact fit; aftermarket filters (Wix, Mann, Bosch, Purolator, Fram) are widely available and usually cost less.
- Cross-reference—If you know the current filter’s cross-reference, you can confirm a compatible option from your preferred brand.
- Specifications to confirm—Ensure the replacement matches thread size, gasket diameter, and filter height to fit in the engine bay without interference.
Using the correct filter will help maintain oil pressure and engine longevity for your Caravan.
Summary
The 2006 Dodge Caravan takes a standard spin-on oil filter, with the exact part number depending on whether your van has the 3.3L or 3.8L V6 engine. Identify your engine and verify the part using the current filter, the owner’s manual, or a trusted parts retailer with your VIN. From there, you can choose an OEM Mopar filter or a compatible aftermarket option that matches the thread size and gasket type.
