What engine is in the 2.4 Honda Accord?

The 2.4-liter Honda Accord uses Honda’s K-series four-cylinder engine. Depending on model year and market, it’s typically a K24A (2003–2007), K24Z (2008–2012), or the Earth Dreams K24W (2013–2017) — all DOHC, 16‑valve, i‑VTEC inline-fours. In the U.S., outputs generally range from about 160–190 hp (2003–2012) and 185–189 hp (2013–2017). Newer Accords (2018-on) no longer use the 2.4-liter engine.

How the answer varies by model year

Honda offered several iterations of the 2.4-liter inline-four across three Accord generations, refining emissions, efficiency, and performance. The exact engine code on your car depends on model year, trim, and region.

2003–2007 (7th generation)

Most markets received the K24A family. In North America, mainstream Accords used the K24A4 initially, updated to the K24A8 from 2006. These are port-injected, DOHC i‑VTEC units producing roughly 160–166 hp and about 160 lb‑ft. They’re chain-driven and known for durability and smoothness.

2008–2012 (8th generation)

The Accord moved to the K24Z series, primarily the K24Z2 in volume trims and K24Z3 in higher-output applications. Still port-injected, these engines typically make around 177 hp (LX/EX) and up to about 190 hp in select EX/EX-L configurations, with torque near 161 lb‑ft.

2013–2017 (9th generation)

The final 2.4L Accord adopted the Earth Dreams K24W architecture with direct injection. In North America, the K24W1 (LX/EX/EX-L) is rated about 185 hp and 181 lb‑ft, while the Sport’s K24W7 tuning yields about 189 hp and 182 lb‑ft, aided by a freer-flowing exhaust. These engines paired with a CVT or a 6-speed manual in some trims.

Key technical features of the 2.4L Accord engines

While codes vary, the 2.4-liter Accord engines share core design and technology traits that define their character and reliability.

• Configuration: Inline-4, 2,354 cc aluminum block and head
• Valvetrain: DOHC, 16-valve with i‑VTEC variable valve timing and lift
• Timing: Chain-driven camshafts (no timing belt)
• Fuel system: Multi-point port injection on K24A/K24Z; direct injection on K24W
• Compression ratio: Typically around 9.7–10.5:1 (K24A/Z); up to ~11.1:1 (K24W)
• Emissions/efficiency: Progressive updates meet tightening standards; Earth Dreams K24W adds DI and friction reduction
• Transmissions: 5-speed auto/manual (2003–2012), CVT or 6-speed manual (2013–2017)

Together, these characteristics deliver the Accord’s well-known balance of smoothness, reliability, and everyday performance.

Typical power and torque by U.S. trims

The 2.4-liter’s output depends on year and trim. The figures below reflect common U.S. ratings; exact numbers can vary slightly by certification and equipment.

• 2003–2005 2.4L (LX/EX): about 160 hp, ~161 lb‑ft
• 2006–2007 2.4L (LX/EX): about 166 hp, ~160 lb‑ft
• 2008–2010 2.4L (LX/EX): about 177 hp, ~161 lb‑ft
• 2008–2012 2.4L (select EX/EX‑L): up to about 190 hp, ~162 lb‑ft
• 2013–2017 2.4L (LX/EX/EX‑L, K24W1): about 185 hp, 181 lb‑ft
• 2013–2017 2.4L Sport (K24W7): about 189 hp, 182 lb‑ft

These ranges capture the evolution from port-injected K24A/Z engines to the more efficient, slightly stronger direct-injected K24W units.

How to confirm your exact engine code

If you need the precise engine designation for parts or documentation, you can verify it directly from your vehicle and paperwork.

• Check the under-hood emissions/engine label: Often lists the engine family/code.
• Locate the engine stamping: Typically on the block’s front side (near the transmission bellhousing) with a code like K24A8, K24Z2, or K24W7.
• Use your VIN: A dealer or parts catalog can decode the exact engine from the VIN.
• Consult the owner’s manual or service records: Many list the engine family and tune.

Verifying the code ensures you get correct specifications and compatible parts for your specific Accord.

Summary

The “2.4” Honda Accord is powered by Honda’s K-series 2.4-liter i‑VTEC inline-four: K24A (2003–2007), K24Z (2008–2012), or direct-injected Earth Dreams K24W (2013–2017). Outputs span roughly 160–190 hp, with the final K24W versions delivering 185–189 hp and improved efficiency. To know exactly which one you have, confirm the engine code via the under-hood label, engine stamping, or VIN.

Is the Honda 2.4 a good engine?

Yes, the Honda 2.4L (K24) engine is generally considered a good and reliable engine, known for longevity, good fuel economy, and decent performance with proper maintenance. However, common issues like oil consumption, timing chain wear, and certain transmission problems can occur, especially with longer oil change intervals or high mileage, but these can often be mitigated with regular maintenance and using the correct oil viscosity.
 
Pros:

• Reliability & Longevity: . Opens in new tabThe 2.4L engine is renowned for its dependability and can last well over 200,000 miles with proper care. 
• Performance & Efficiency: . Opens in new tabIt delivers a good balance of power, low-end torque, and fuel economy, with many users reporting high MPG even on older models. 
• VTEC System: . Opens in new tabThe VTEC variable valve-timing system enhances high-rpm power, making the engine feel more engaging. 
• Timing Chain: . Opens in new tabUnlike older engines with timing belts, the 2.4L uses a timing chain, which is designed to last the life of the engine. 

Potential Issues & Maintenance:

• Oil Consumption: Some 2.4L engines may consume oil over time; this is often manageable by monitoring oil levels and topping off as needed. 
• Timing Chain Wear: The timing chain and its components can wear out, especially with longer oil change intervals, potentially leading to noise (like rattling) or jumping. Regular oil changes with recommended grades are crucial for chain longevity. 
• Sludge Buildup: Longer oil change intervals can lead to sludge, which can affect the engine’s overall health and the timing chain. 

To Keep Your 2.4L Engine Running Well: 

• Regular Oil Changes: Adhere to recommended oil change intervals and use the appropriate oil viscosity to prevent sludge and ensure proper lubrication of the timing chain.
• Monitor Oil Levels: Check your oil level regularly and top it off as needed.
• Address Leaks Promptly: Fix oil leaks as soon as they are detected.
• Routine Inspections: Inspect components like the valve cover gasket and PCV valve to prevent issues.
