What acuras have a K24?
The primary Acura model that used a 2.4-liter K-series engine is the TSX, which relied on two different K24 variants over its production run. Specifically, the TSX used K24A2 in its early years and transitioned to K24Z3 in later years.
To understand what this means in context: the K24 family is Honda’s 2.4L line of inline-four engines, and Acura’s adoption of this family has been relatively limited compared with other Honda models. This article focuses on verified, production-vehicle usage in the Acura lineup as of today, with notes on how to identify a K24-powered car.
K24-powered Acuras
Below is a concise breakdown of the confirmed K24-powered Acura production model(s):
- 2004–2008 Acura TSX — K24A2
- 2009–2014 Acura TSX — K24Z3
These two TSX generations cover the documented K24 applications in Acura's lineup. Other Acuras have not used the K24 as a standard, widely advertised engine option.
Notes on verification and broader context
How to verify whether a specific Acura uses a K24 engine: locate the engine code on the engine block or valve cover. For the TSX, the codes you’ll see are K24A2 (earlier TSX) or K24Z3 (later TSX). Engine codes can vary by market and model year, so a direct VIN-based check or dealer confirmation provides the most reliable verification.
Where to find the engine code
Inspect the front or side of the engine block or the valve cover; the code is usually stamped or plated in that area. Cross-check the code with production-year information to confirm it is a K24 variant rather than another K-series engine.
Summary
In Acura’s current production history, the K24 engine is most closely associated with the TSX, appearing in two generations: K24A2 (2004–2008) and K24Z3 (2009–2014). Other Acura models have not featured a widely documented K24 variant in production. If you’re evaluating a used Acura for K24 power, prioritize a TSX and verify the engine code on the block to confirm the exact K24 variant.
