Does a 2004 Acura TSX have VTEC?
Yes. The 2004 TSX uses a 2.4-liter i-VTEC engine with VTEC engaged on the intake cam, delivering about 200 horsepower.
The TSX, launched in 2004, was Honda’s sport-oriented sedan built on the Accord platform. Its VTEC system is designed to boost high-RPM power while preserving low-end torque for everyday driving, aligning with the model’s balance of performance and practicality.
Engine and VTEC details
Key facts about the engine and how VTEC works in this model:
- Engine: 2.4-liter inline-4 (K24A2)
- Valvetrain: i-VTEC with VTEC on the intake cam (exhaust cam is not VTEC)
- Configuration: Double overhead camshaft (DOHC)
- Horsepower: ~200 hp
- Torque: ~164 lb-ft
- Redline: around 7,000 rpm
- Drivetrain: Front-wheel drive
These specifications describe the TSX engine setup typical for the 2004 model year, with variations by market. The i-VTEC system is specifically designed to alter the intake cam profile to improve top-end power while maintaining low-end responsiveness.
Driving experience and maintenance
In practice, VTEC in the TSX engages at higher RPMs, shifting to a higher cam profile to unlock more power. For daily driving, the engine remains tractable and refined, while at highway speeds or during spirited driving, the power spike from the VTEC sequence becomes noticeable. Regular maintenance—oil changes, timing belt/drive belt replacement, coolant service, and proper valve-cover gaskets—helps ensure the VTEC system and overall engine stay healthy.
Practical notes for prospective buyers
Before reviewing or purchasing a 2004 TSX, consider the following:
- Confirm the intake-cam VTEC operation and listen for the VTEC transition sound at higher RPMs (typically around 5,000–6,000 rpm).
- Check service history for recommended maintenance: timing belt replacement intervals, water pump, and oil changes using appropriate oil grade.
- Inspect for common wear items: suspension components, brakes, and any oil leaks around the valve cover or cam seals.
Proper evaluation can help determine if a used TSX with this engine is in good shape and capable of delivering the intended driving experience.
Summary
Yes—the 2004 Acura TSX features Honda’s i-VTEC 2.4-liter engine with VTEC on the intake cam. This setup provides a balance of strong high-RPM performance and everyday drivability, backed by around 200 horsepower and a refined driving character. With regular maintenance, the TSX can remain a capable and engaging sports sedan within its era.
