The K24 family, a 2.4-liter engine lineage from Honda, appears in several Honda and Acura models. Key examples include the Acura TSX and various 2.4L Hondas such as the CR-V, Element, and some Accord variants.
Overview of the K24 engine family
The K24 engines are part of Honda’s K-series, built as 2.4L inline-4 powerplants with DOHC and VTEC in many versions. Variants are identified by codes such as K24A1, K24A2, K24A3, K24A4, K24A8 and K24Z1, and they were used across different model years and markets. Engine codes matter for compatibility, swaps, and repairs, because each variant can have slightly different hardware, intake configurations, and ECU calibrations.
Below is a concise inventory of mainstream Honda and Acura models that used K24 family engines in North America, with the variant most commonly cited for each.
- Acura TSX — K24A2 (years roughly 2004–2008). A primary home for the 2.4L K-series in the Acura lineup, known for its i-VTEC setup and sport-oriented characteristics.
- Honda CR-V — K24 family variants include K24A1 in earlier generations and K24Z1 in later US-market models (roughly 2002–2011, with regional variations). This is the most common 2.4L option in CR-V histories.
- Honda Element — K24A1 (early to mid-2000s models; Element used a 2.4L engine in several markets and trims).
- Honda Accord — 2.4L variants appeared in some markets and trims (commonly cited as K24A4 and related variants), depending on year and regional specification.
These listings reflect widely cited configurations in popular service guides and aftermarket references. Exact engine code and compatibility can vary by year, region, and vehicle trim, so double‑checking the stamped engine code is essential before any work or swaps.
How to confirm your specific K24 variant
To identify your exact K24 variant, start with the engine code stamped on the engine block or valve cover. Cross-reference the code with your vehicle’s VIN and the official Honda/Acura service literature for your market. If you’re planning maintenance, repairs, or a swap, verifying the variant helps ensure correct parts and ECU compatibility.
- Check the valve cover or timing belt/chain side for the engine code (e.g., K24A1, K24A2, K24Z1, K24A4, K24A8).
- Use the vehicle’s VIN to pull a factory engine specification sheet from a dealer or reliable online database.
- Consult a qualified mechanic or Honda/Acura specialist if you’re considering a swap, since variant compatibility matters for mounts, sensors, and ECU tuning.
Knowing the precise K24 variant helps with parts sourcing, maintenance intervals, and potential performance work. If in doubt, err on the side of confirming the engine code first rather than assuming based on model alone.
Summary
Key takeaways about Honda K24 engines:
- The K24 family appears in several Honda/Acura models, notably the Acura TSX and various 2.4L Honda models.
- Common North American examples include the TSX (K24A2), early CR-Vs (K24A1) and later CR-Vs (K24Z1), and the Honda Element (K24 variants).
- Engine variant identification is important for maintenance, repairs, and any engine swaps; verify the exact code from the engine itself and cross-reference with the VIN.
