Yes. The K24 is a 2.4-liter inline-four engine from Honda’s K-series family.
In practice, the designation K24 denotes a family of roughly 2.4-liter engines. Most variants sit around 2,354 cubic centimeters (about 2.35 L), with small, model-year– and market-based differences. This article explains what that means, where the displacement comes from, and which vehicles commonly use these engines.
Displacement basics and variant range
The K24 line is built around a 2.4-liter block. In most variants, the official displacement is approximately 2.35 L (2,354 cc), although exact figures can vary by specific variant and regional market.
Before listing the main variants, it’s useful to know that the K24 family includes several sub-variants with minor differences in bore, stroke, and valve timing. These tweaks can adjust power delivery and efficiency while keeping the overall displacement in the 2.3–2.4 liter class.
- K24A-series engines commonly cited around 2,354 cc (2.354 L) in many markets.
- K24Z-series engines also around 2,354 cc (2.354 L), with small market-specific adjustments in some cases.
- Other K24 sub-variants generally stay in the same 2.35 L vicinity, with minor deviations due to bore/stroke differences.
In practical terms, when people refer to a K24 as a 2.4 L engine, they are noting the broad displacement class rather than an exact factory-stamped figure. For precise numbers, the exact engine code (for example, K24A or K24Z) and the model year should be checked.
Popular variants and where they appear
Below are well-known K24 variants and the vehicles in which they were commonly used. Do note that exact engine codes can vary by market and production year.
- Acura TSX (2004–2008) — commonly K24A2 or K24A3 2.4 L
- Honda Accord (early 2000s) — K24A-based 2.4 L configurations
- Honda CR-V (2002–2006) — 2.4 L K24A
- Honda Element (2003–2011) — 2.4 L K24A
These applications illustrate how the same 2.4 L displacement was adapted across sedans, crossovers, and niche models, with variations in intake, exhaust, and valvetrain to suit different performance and efficiency goals.
Technical notes: displacement, power, and variants
What “2.4 L” means in practice
The 2.4 L label refers to the engine’s swept volume—the total air and fuel that can be drawn through the cylinders during one complete combustion cycle. It’s a structural characteristic, not a guarantee of horsepower or torque. Variants with VTEC or i-VTEC timing, different intake manifolds, and other tuning differences can produce a broad range of power outputs within the same displacement class.
Why displacement numbers vary between variants
Even within the K24 family, differences in bore and stroke, cylinder head design, and auxiliary equipment lead to small changes in exact displacement. Market-specific emissions standards and model-year updates can also yield minor cc fluctuations. For exact numbers, consult the engine code stamped on the block or the official specifications for the vehicle in question.
Summary
The K24 is fundamentally a 2.4-liter engine family. The designation signals a displacement around 2.35 L (about 2,354 cc), but exact figures vary by variant and market. This family has been used across several Honda and Acura models, including the TSX, Accord, CR-V, and Element, often with different intake, cam timing, and tuning to suit each model’s goals. When precision matters—such as sourcing parts or verifying compatibility—check the exact engine code (for example, K24A or K24Z) and the vehicle’s year.
