The Best Header and Intake Combo for K24 Power: a 100 Hp Increase in a Weekend

by

The K24 engine is a popular choice among car enthusiasts looking to enhance performance. With the right modifications, it’s possible to achieve significant horsepower gains in a short amount of time. In this article, we will explore the best header and intake combo for the K24 engine that can yield a remarkable increase of 100 horsepower over a weekend.

Understanding the K24 Engine

The K24 is a 2.4-liter inline-four engine produced by Honda. Known for its reliability and performance potential, it provides a solid foundation for tuning. It features a DOHC design and is commonly found in various Honda models, including the Accord and CR-V. Tuning the K24 can lead to impressive power increases, especially when focusing on the intake and exhaust systems.

Benefits of Upgrading the Header and Intake

Upgrading the header and intake system is one of the most effective ways to enhance engine performance. Here are some key benefits:

  • Increased airflow: A high-performance header and intake allow for better air circulation, leading to improved combustion.
  • Enhanced throttle response: Upgrades can reduce restrictions, resulting in quicker acceleration.
  • Higher horsepower: Optimized airflow directly correlates with increased power output.
  • Better sound: Many aftermarket headers provide a more aggressive exhaust note.

Choosing the Right Header

When selecting a header for the K24, consider the following factors:

  • Material: Stainless steel headers offer durability and resistance to corrosion, while mild steel is often cheaper but less durable.
  • Design: Long-tube headers typically provide better performance at higher RPMs, while short-tube headers can enhance low-end torque.
  • Compatibility: Ensure the header is designed specifically for the K24 engine and fits your vehicle model.

Here are some top-rated headers for the K24 engine:

  • DC Sports 4-2-1 Header: Known for its excellent performance and fitment.
  • Skunk2 MegaPower Header: Offers a great balance of power and sound.
  • Greddy Header: Renowned for its quality and performance gains.

Selecting the Right Intake System

The intake system plays a crucial role in how effectively the engine breathes. Here’s what to consider:

  • Type: Cold air intakes typically provide better performance than short ram intakes due to cooler air temperatures.
  • Filter quality: High-flow air filters can significantly improve airflow and filtration.
  • Design: Look for intakes that minimize bends and restrictions in airflow.

Here are some highly regarded intake systems for the K24 engine:

  • K&N 69 Series Typhoon Intake: Known for its excellent airflow and filtration.
  • AEM Cold Air Intake: Offers significant horsepower gains and a great sound.
  • Injen SP Series Intake: Features a unique design for improved performance.

Installation Process

Installing a new header and intake system can typically be done over a weekend with basic tools. Here’s a brief overview of the installation process:

  • Gather necessary tools: You’ll need basic hand tools, a torque wrench, and possibly a lift or jack stands.
  • Remove the old header: Disconnect the exhaust and unbolt the old header from the engine.
  • Install the new header: Position the new header and secure it with bolts, following the manufacturer’s torque specifications.
  • Replace the intake system: Remove the old intake and install the new one, ensuring all connections are secure.

Tuning for Maximum Performance

After installing the new header and intake, tuning the engine is essential to maximize performance gains. Here are some tuning options:

  • ECU Reflash: A software update can optimize fuel maps for the new modifications.
  • Standalone ECU: For serious tuners, a standalone ECU allows for complete control over engine parameters.
  • Dyno Tuning: A professional dyno tune can ensure your engine runs efficiently and safely.

Conclusion

Upgrading the header and intake system on a K24 engine can lead to impressive horsepower gains, potentially reaching 100 additional horsepower with the right combination of parts and tuning. By selecting quality components and following proper installation and tuning procedures, enthusiasts can enjoy significant performance improvements in a short amount of time. Whether you’re a weekend warrior or a dedicated tuner, these upgrades can transform your K24 engine into a powerhouse.
