The 2004 Honda Accord LX uses a 2.4-liter inline-4 i-VTEC engine from Honda’s K-series family, delivering about 160–166 horsepower and roughly 160 lb-ft of torque.
In the 2004 model year, the LX trim line used this four-cylinder engine as standard, part of Honda’s seventh-generation Accord introduced in 2003. A 3.0-liter V6 option was available on higher trims, but LX models with four cylinders were equipped with the 2.4L engine.
Engine specifications
Here are the core technical specifications for the 2.4-liter i-VTEC engine commonly found in the 2004 Accord LX:
- Displacement: 2.4 liters
- Configuration: Inline-4
- Valvetrain: i-VTEC, double overhead camshafts (DOHC)
- Horsepower: about 160–166 hp (varies by market and emission tuning)
- Torque: around 160 lb-ft
- Engine code: K-series (K24A family, a common variant in 2004 Accords)
- Fuel system: Sequential multi-point fuel injection
In practice, most U.S.-market 2004 Accord LX models with the 2.4L engine produced roughly 160–166 horsepower and 160 lb-ft of torque, delivering a balance of everyday responsiveness and fuel efficiency.
Context and maintenance considerations
For the 2004 Accord’s 2.4L engine, Honda relied on a timing chain rather than a timing belt, reducing the risk of belt-change maintenance intervals. Routine maintenance remains critical for longevity, including regular oil changes, coolant maintenance, and air/fuel-system upkeep.
- Oil changes roughly every 5,000–7,500 miles depending on driving conditions and oil specification.
- Check and replace air filters, and monitor coolant levels as part of the cooling system maintenance.
- Inspect the drive belts/passages (if any) and ensure ignition components are in good condition.
These maintenance steps help ensure reliable performance from the 2.4L i-VTEC engine in the long term.
Verification and quick facts
If you own or are shopping for a 2004 Accord LX and want to confirm the exact engine variant, check the engine code stamped on the engine block or consult the vehicle’s VIN-based build sheet. Most LX models in the U.S. used the 2.4L i-VTEC engine, but regional or rare market variations could differ.
Summary
The 2004 Honda Accord LX is powered by a 2.4-liter inline-4 i-VTEC engine from Honda’s K-series, producing roughly 160–166 horsepower and about 160 lb-ft of torque. It represents the standard four-cylinder option in the seventh-generation Accord, with a V6 available on higher trims. Proper maintenance remains key to ensuring long-term reliability and performance.
