The 2004 Honda Accord came with two engine options. The base engine is a 2.4-liter DOHC i-VTEC 4-cylinder (K24A4) producing 160 horsepower and 161 lb-ft of torque. This naturally aspirated engine features Honda’s Variable Valve Timing and Lift Electronic Control (VTEC) system for improved performance and fuel economy. The 2.4L engine was paired with either a 5-speed manual or 5-speed automatic transmission. It delivers approximately 24 city/34 highway MPG and runs on regular unleaded gasoline. The V6 option was a 3.0-liter SOHC VTEC V6 producing 240 horsepower.

The 2004 Honda Accord shares most parts with the 2003-2007 seventh generation Accord models. Engine components from the 2.4L K24A4 are largely interchangeable across these years, though minor variations exist in sensors and accessories. Body panels, interior components, suspension parts, and most mechanical systems are compatible within this generation. Some electrical components and ECU modules may have year-specific programming requirements. The transmission used in 2004 models is also found in 2003-2005 models with the same engine. Always verify part numbers when possible, as Honda made running changes throughout production years.

The 2.4L K24A4 engine in the 2004 Accord is generally reliable and can easily exceed 200,000 miles with proper maintenance. The VTEC system is robust and the engine responds well to regular oil changes every 5,000 miles using 5W-30 oil. Common maintenance items include timing chain tensioner replacement around 150,000 miles and valve adjustments every 110,000 miles. The engine is not an interference design, so timing chain failure won’t cause valve damage. Regular coolant changes prevent head gasket issues, and using quality oil prevents VTEC solenoid problems that can cause rough idle.
