The 2006 Acura TSX comes equipped with a 2.4-liter DOHC i-VTEC inline-4 engine designated as the K24A2. This naturally aspirated engine produces 200 horsepower at 6,800 RPM and 166 lb-ft of torque at 4,500 RPM. The engine features Honda’s Variable Valve Timing and Lift Electronic Control (VTEC) system, which optimizes performance and fuel efficiency across the RPM range. The K24A2 uses a timing chain rather than a belt, reducing maintenance requirements. It’s paired with either a 5-speed automatic transmission or a 6-speed manual transmission, delivering an EPA-estimated 23 mpg city and 31 mpg highway with the manual transmission.

The 2006 Acura TSX shares most parts with the 2004-2008 first-generation TSX models, as they’re built on the same CL9 platform. Engine components from the K24A2 are largely interchangeable across all first-generation years. Body panels, interior components, and most mechanical parts interchange within this generation. Some electrical components and ECU modules may have year-specific programming requirements. The 2009-2014 second-generation TSX uses a different platform and has limited parts compatibility. Suspension components, brakes, and many engine accessories are direct fits across 2004-2008 models, making parts sourcing relatively straightforward for this generation.

The K24A2 2.4L engine in the 2006 TSX is generally reliable and can easily exceed 200,000 miles with proper maintenance. The timing chain design eliminates belt replacement concerns, and the engine responds well to regular oil changes every 5,000 miles. Common maintenance items include valve adjustments every 30,000 miles and spark plug replacement every 60,000 miles. The VTEC system is robust but requires clean oil to function properly. While carbon buildup on intake valves can occur over time, regular highway driving and quality fuel help minimize this issue. Overall, this engine offers good longevity when maintained properly, though manual transmission models should have the clutch inspected regularly due to known premature wear issues.
