The K24 engine family appears in several Honda and Acura models, most notably the CR-V, Element, Accord, and Acura TSX, as a 2.4-liter inline-four with multiple variants used across different markets.
Which Honda models used a K24 engine
Below are the best-known Honda and Acura models that used the 2.4-liter K-series in various generations and markets. Engine codes varied by year and region, but these vehicles are consistently associated with the K24 platform.
- Honda CR-V (2002–2006) — 2.4L i-VTEC, K24A1
- Honda Element (2003–2011) — 2.4L i-VTEC, K24A4
- Honda Accord (2003–2007) — 2.4L i-VTEC, K24A1/K24A2 variants
- Acura TSX (2004–2008) — 2.4L i-VTEC, K24A2
In addition, some markets or trims of other models used a K24 variant, and later Honda vehicles shifted toward turbocharged engines or different powerplants for efficiency or emissions goals. When shopping for a used vehicle, confirm the exact engine code with the VIN or dealer documentation.
About the K24 family
The K24 is a family of 2.4-liter inline-four engines produced by Honda as part of the K-series. It features double-overhead cams and i-VTEC variable valve timing, with multiple variants designed to balance power, torque, and efficiency for different models and markets.
Design notes
Common traits across K24 variants include aluminum construction, DOHC architecture, and a chain-driven cam system. The engines were paired with a range of transmissions, from manual to automatic, across front- and all-wheel-drive configurations.
Maintenance considerations include periodic timing chain inspection, proper ignition and fuel system maintenance, and ensuring the i-VTEC system components are in good condition to preserve performance and efficiency.
Summary
The K24 engine remains a notable chapter in Honda’s engineering history, powering several mainstream models in the 2000s and early 2010s. Its legacy lives on in discussions of reliability, ease of tuning, and the brand’s reputation for practical, durable four-cylinder performance.
