Your 2004-2008 Acura TSX's K24A2 engine is one of Honda's best four-cylinders — but it's being strangled by the stock airbox. This Flashark Cold Air Intake replaces that restrictive setup with a Φ76mm mandrel-bent aluminum pipe and a high-flow red cone filter, giving you sharper throttle response, better mid-range pull, and the induction growl these engines are known for.
Built specifically for the 2.4L DOHC K-series engine, this kit features a dual-breather nozzle design and a reducer coupler for exact fitment. The integrated bracket bolts directly to factory mounting points. No drilling, no cutting — about 60 minutes with basic hand tools.

2004-2008 Acura TSX 2.4L Cold Air Intake Kit FAQ
Q1: What vehicles does this 2004-2008 Acura TSX cold air intake fit?
A1: This cold air intake kit is designed for 2004-2008 Acura TSX models equipped with the 2.4L K24A2 inline-4 engine. It is a direct bolt-on upgrade for the factory intake system on both automatic and manual transmission vehicles.
Q2: Does this intake fit all 2004 Acura TSX models?
A2: Yes, it fits all 2004 Acura TSX models with the 2.4L K24 engine. Always confirm your engine type before ordering, as this kit is not compatible with non-TSX Honda or Acura engines.
Q3: Will this cold air intake fit a 2008 Acura TSX?
A3: Yes, it is fully compatible with the 2008 Acura TSX 2.4L. The intake system is designed to match the factory MAF sensor and OEM intake mounting points.
Q4: What engine is in the Acura TSX 2004-2008?
A4: The 2004-2008 Acura TSX uses the 2.4L K24A2 DOHC i-VTEC engine. This engine responds well to improved airflow modifications such as a cold air intake system.
Q5: Will this intake increase horsepower on a K24 engine?
A5: Yes, but gains are moderate. Most users experience approximately 5–12 horsepower depending on supporting modifications, engine condition, and tuning. The biggest improvements are throttle response and intake sound.
Q6: Does this cold air intake improve throttle response?
A6: Yes, the smoother aluminum intake path and high-flow filter reduce restriction, which improves throttle response especially in mid and high RPM ranges where the K24 engine performs strongly.
Q7: Will this intake make my Acura TSX louder?
A7: Yes, it increases induction sound noticeably during acceleration. The K24 engine produces a deeper intake tone and more aggressive airflow sound compared to the factory airbox.
Q8: Do I need a tune after installing this intake?
A8: No ECU tune is required for basic installation. The factory ECU can adapt to the increased airflow on the K24A2 engine under normal driving conditions.
Q9: Will this intake trigger a check engine light?
A9: A properly installed intake should not trigger a check engine light. Issues typically occur only if the MAF sensor is not installed correctly or if there is an air leak in the system.
Q10: Is this a cold air intake or a short ram intake?
A10: Depending on configuration, this kit may function as either a cold air intake or short ram intake. Cold air setups pull cooler outside air, while short ram designs focus on quicker throttle response.
Q11: Is the filter reusable and washable?
A11: Yes, the kit includes a reusable and washable high-flow cone filter designed for long-term performance use with proper maintenance.
Q12: Is this intake safe for daily driving?
A12: Yes, it is designed for daily driving use when installed correctly. It maintains stable airflow and is suitable for both city and highway driving conditions.
Q13: Can I drive in rain with a cold air intake on my TSX?
A13: Yes, normal rain driving is safe. However, avoid deep water or flooding conditions, as any exposed filter intake system can increase the risk of water ingestion.
Q14: Does this intake improve fuel economy?
A14: Fuel economy improvements are not guaranteed. Some drivers may see slight gains under steady cruising, but MPG depends more on driving habits, maintenance, and vehicle condition.
Q15: How difficult is installation?
A15: Installation is bolt-on and typically takes 30–60 minutes using basic hand tools. No cutting or permanent modification is required for 2004-2008 Acura TSX applications.
Q16: What is the main benefit of upgrading to this intake?
A16: The main benefits include improved airflow efficiency, sharper throttle response, stronger engine sound, and a more performance-oriented engine bay for the Acura TSX K24 platform.
