The 2004 Honda Accord offered two engine options in the United States: a 2.4-liter inline-4 (K-series) and a 3.0-liter V6 (J-series). The exact choice depended on trim level and market, with corresponding differences in horsepower and torque.
Two engine options in the 2004 Accord
The U.S.-market 2004 Accord was available with either a four-cylinder or a V6 powerplant. Below is a quick overview of each engine family and typical outputs.
- 2.4-liter inline-4 (K-series) — A member of Honda’s K-family, commonly delivering roughly 160–166 horsepower and about 160–165 lb-ft of torque. Engine codes in this era include variations such as K24A4/K24A8, depending on trim and emission equipment.
- 3.0-liter V6 (J-series) — A larger V6 offering around 240 horsepower and roughly 210–221 lb-ft of torque, with engine codes such as J30A1/J30A5 used in different models and markets.
Note: Exact outputs and engine codes can vary by trim level and regional market, so checking the specific vehicle's VIN or window sticker is the best way to confirm.
Which trims used which engine
Engine choice was tied to trim level in most configurations. The four-cylinder appeared in the DX/LX/EX lineups, while the V6 powerplant was reserved for higher trims.
- 4-cylinder 2.4 L I-4 for DX/LX/EX trims
- 3.0 L V6 for EX V6 (and related higher-end trims)
In some markets or for certain sedan configurations, both engine options were offered, while other regions may have limited one of the powertrains.
Performance and specs at a glance
The 4-cylinder setup emphasized efficiency with modest horsepower, while the V6 provided stronger acceleration and higher torque. Typical figures (varying by year and market) place the 4-cylinder around 160–166 hp and about 160–165 lb-ft of torque, and the V6 around 240 hp and 210–221 lb-ft of torque. Transmission options varied by trim and market, including both manual and automatic choices.
For owners or buyers, the exact engine code and output can be confirmed via the vehicle’s VIN or the original window sticker.
How to verify your specific engine
To verify the exact engine in a particular 2004 Accord, check the engine code stamped on the engine block or consult the VIN plate under the hood. The owner’s manual or dealership records can also confirm whether the car is equipped with the 2.4 L I-4 (K-series) or the 3.0 L V6 (J-series).
Conclusion
The 2004 Honda Accord offered two primary powertrains: a 2.4-liter inline-4 and a 3.0-liter V6. The four-cylinder was more common across the base and mid trims, while the V6 was selected for higher-trim models and variants, delivering notably more power and torque.
Summary
In summary, the 2004 Honda Accord could be equipped with either a 2.4 L K-series four-cylinder or a 3.0 L J-series V6, with the choice depending on trim and market. Verify the exact engine in a given car using the VIN, window sticker, or owner documentation.
