The 2007 Acura TSX uses a 2.4-liter inline-4 i-VTEC engine from Honda’s K-series family, typically identified as the K24A2 for US-market cars. It produces about 200–205 horsepower and roughly 160–164 lb-ft of torque.
Engine family and specs
The TSX from 2004 through 2008 is equipped with a single, high-revving 2.4-liter four-cylinder from Honda’s K-series. This engine pairs variable valve timing (i-VTEC) with dual overhead cams to deliver a broad power band that suits the TSX’s sporty yet refined character. In most documentation and owner references, the US-market engine is noted as the K24A2.
Key technical details for quick reference:
- Engine displacement: 2.4-liter (approximately 2,350–2,400 cc range)
- Configuration: Inline-4
- Valvetrain: DOHC with i-VTEC
- Induction: Multi-point fuel injection
- Power output: About 200–205 horsepower
- Torque: About 160–164 lb-ft
- Redline: Roughly around 7,000 rpm
- Fuel system: Port/fuel injection with variable valve timing
- Ignition: Electronic ignition system (distributorless)
- Timing mechanism: Chain-driven
- Engine code: K24A2 (US market)
Concluding, the 2007 TSX centers on Honda’s reliable 2.4-liter K-series inline-4 with i-VTEC, delivering a competitive blend of power and refinement for a compact sport sedan of its era.
Notes on variants and maintenance considerations
While the US TSX consistently relies on the K24A2 configuration, there are occasional market-specific calibrations and emissions tuning. For owners, the most relevant maintenance considerations center on the timing chain-driven nature of the engine, regular oil changes with appropriate viscosity, and attention to VVT solenoids and related sensors, which can influence performance and fuel economy over time.
In practice, keeping up with routine maintenance is key to preserving the engine’s responsiveness and longevity. Common checks include oil level and quality, coolant condition, and periodic inspection of the variable valve timing system to ensure smooth power delivery across the rev range.
Summary
The 2007 TSX is powered by Honda’s 2.4-liter K-series inline-4 with i-VTEC, widely identified as the K24A2 in US models. It offers a practical balance of horsepower and torque for a sport-oriented compact sedan, with a dependable timing-chain setup and a design that emphasizes rev-friendly performance and smooth, linear delivery.
