The 2.4-liter inline-four, part of Honda’s K-series family, was used in a handful of models primarily in the 2000s, most notably the Accord, CR-V, Element, and Acura TSX.
Across this report, we break down which Honda models offered the 2.4L engine, the typical years it appeared, and what to know about its variants and compatibility for prospective buyers or current owners seeking parts or maintenance information.
Models that used the 2.4L engine
The following list summarizes the main Honda and Acura models commonly equipped with the 2.4-liter inline-four. Year ranges can vary by market and trim, and some regions offered alternative engines during overlapping years.
- Honda Accord (four-cylinder trims in the mid-2000s, roughly 2003–2007; 2.4L K-series variants)
- Honda CR-V (early-to-mid-2000s; around 2002–2006/2007; 2.4L K-series)
- Honda Element (2003–2011; 2.4L K-series)
- Acura TSX (2004–2008; 2.4L K24A2)
Availability and exact engine code can vary by model year and market. If you’re shopping used, verify the engine designation on the engine block and confirm with the VIN and owner’s manuals for exact specifications.
Engine variants and compatibility
The 2.4L family is part of Honda’s K-series, which includes several variants tuned for different models and emissions requirements. Notable examples include K24A1 and K24A2, used across CR-V, Element, Accord, and TSX in various years. While the displacement is the same, differences in intake, cam timing, and ECU calibration can affect parts compatibility, maintenance intervals, and diagnostic procedures.
To ensure proper parts compatibility, owners should check the engine code stamped on the engine block or consult the vehicle’s documentation to confirm whether a given engine is K24A1, K24A2, or another K-series variant.
Why this matters for buyers and owners
Knowing which Hondas used the 2.4L engine helps with parts availability, maintenance planning, and resale decisions. Aftermarket and dealer support for the K-series 2.4L is robust, but precise variant codes matter for timing belts/chains, compatibility with intake and exhaust components, and ECU programming.
Summary
The 2.4-liter inline-four was a prominent option in several Honda and Acura models during the 2000s, most notably the Honda Accord, CR-V, Element, and Acura TSX. While the exact variant (such as K24A1 or K24A2) varied by model and year, these four vehicles represent the core lineup associated with the 2.4L engine. Prospective buyers and current owners should verify the specific engine code and year to ensure accurate parts compatibility and maintenance planning.
