Yes. In 2004, the four-cylinder Honda Accord uses a K-series 2.4-liter engine (the K24 family). The available V6 variant uses Honda's J-series engine, not K.
What powertrains were available in the 2004 Accord?
The 2004 Accord lineup offered two main engine families. The four-cylinder models used a 2.4-liter i-VTEC from the K-series, while the V6 models used a 3.0-liter J-series. The following list highlights the K-series 2.4L options and how they are identified.
- 2.4-liter i-VTEC inline-4 (K-series): the standard powerplant for most 2004 Accord trims
- Engine codes vary by market and trim (examples include K24A1, K24A3, K24A4, etc.; the exact code depends on year and region)
- The 3.0-liter V6 (J-series) was offered as the alternative, not a K-series engine
Note: The exact K24 code can differ by model year and region, so check the engine stamping or service records for the precise variant.
How to confirm a K24 on your 2004 Accord
To confirm whether your car features a K24 engine, inspect the engine block for the code. The K-series four-cylinders will show a K24 prefix, while the V6 will show a J-series code. You can also verify via the VIN or the owner's manual and service records.
Tips for locating the engine code
- Engine code stamping near the front or side of the block, often visible after removing a shield or cover
- Look for a label on the underside of the hood or on the engine compartment wall that lists the engine code
- Cross-check the code with Honda’s official documentation for 2004 Accord variants
Identifying the exact code helps when ordering parts or researching maintenance, as even within the K24 family there are several sub-variants with different intake, exhaust, or sensor configurations.
Summary
Bottom line: a 2004 Honda Accord with a four-cylinder drivetrain uses a K-series 2.4-liter engine (K24), while the six-cylinder version uses a J-series engine. The precise K24 variant (such as K24A3 or K24A4) depends on the market, year, and trim. Checking the engine code stamped on the block or reviewing the VIN will confirm the exact variant for a given car.
