The K24 is Honda’s 2.4-liter inline-4 from the K-series, used across several Honda and Acura models. The most well-known applications are the Acura TSX and Honda CR-V, along with certain Accord and Element versions.
What is the K24 engine?
The K24 is part of Honda’s K-series family of four-cylinder engines. It displaces 2.4 liters and is built with an aluminum block and head, typically featuring double overhead camshafts (DOHC) and variable valve timing (VTEC) on many variants. Introduced in the early 2000s, the K24 was tuned for a mix of reliability and performance across a range of vehicles. Power and torque vary by variant and market, but most K24 engines deliver strong mid-range torque in a 2.4-liter package, roughly in the 160–210 horsepower range, with torque in the neighborhood of 160–165 lb-ft depending on configuration.
Where you’ll find the K24 in Honda/Acura lineups
The K24 engine has powered a number of mainstream Honda and Acura models, especially in the 2000s. The following models are the best-known examples of factory K24 use in North American market cars.
- Acura TSX (2004–2008) — 2.4-liter engine delivering around 205–210 hp
- Honda Accord (2003–2007, 4-cylinder variants) — 2.4-liter option in higher trims/markets
- Honda CR-V (2002–2006/2007) — 2.4-liter option in early second-generation CR-Vs
- Honda Element (2003–2011) — 2.4-liter engine for most trims
These are the primary, widely known applications of the K24 family in common consumer vehicles. Other regional variants and late-model updates may appear in different markets, but the TSX, Accord, CR-V, and Element are the core examples most enthusiasts reference when discussing the K24.
Variants and performance notes
Engine variants within the K24 family differ by code (for example, K24A, K24Z, and related designations) and by tuning for horsepower and torque. In general, the 2.4-liter K-series engines use a timing chain rather than a timing belt, and many have VTEC on the intake side for improved breathing at higher RPMs. If you’re evaluating a used K24-powered vehicle, check the exact engine code for precise specs and recall/service history, as there are important differences between model years.
Summary
The K24 is a cornerstone of Honda’s 2.4-liter, four-cylinder lineup, powering a range of widely sold models—most notably the Acura TSX, Honda CR-V, Honda Accord, and Honda Element—across the early 2000s to early 2010s. Its blend of performance and efficiency made it a common choice for mid-size sedans and compact SUVs in that era.
