Does the ILX have a K24?
Yes — the ILX can be equipped with a 2.4-liter K-series engine in certain trims, while the base model uses a smaller 2.0-liter K-series engine.
The Acura ILX, launched in 2013 as a premium compact sedan, has offered two inline-four options from Honda’s K-series family. The 2.4-liter variant (K24) provides more power, but its availability depended on model year and market. This article explains whether the ILX uses a K24 and how to identify which engine your car has.
Engine options in the ILX
Two K-series configurations have appeared in the ILX lineup. Here is a concise overview:
- 2.0 L i‑VTEC inline-four (K20 family) — the standard engine in the majority of ILX models.
- 2.4 L i‑VTEC inline-four (K24 family) — an optional upgrade on select trims and model years (notably around 2014–2015 in the U.S.).
The 2.4L option is part of Honda’s K-series family and offers a displacement increase over the base 2.0L. Availability varied by year and market, so not every ILX received the K24.
How to verify your ILX’s engine
To confirm the exact engine in your ILX, check these indicators:
- Engine code stamped on the valve cover or near the timing area (examples: K20Z1, K24Z3).
- VIN and build sheet to cross-check the original engine specification.
- Owner’s manual or the window sticker/Monroney—often lists the engine type.
- Under-hood labels or service history indicating which engine was installed.
Directly inspecting the engine code on the block or consulting a dealer with the VIN is the most reliable way to confirm whether you have a K24 or a K20 engine.
Summary
The ILX can use a 2.4-liter K-series engine in certain trims, but the standard model typically uses a 2.0-liter K-series engine. If you’re unsure which engine yours has, verify the engine code (K20 vs K24) via the engine stamping or VIN to ensure accurate identification for maintenance or parts needs.
