Cold Air Intake for Honda Accord LX EX (2008-2012) 2.4L Engine

High-Flow Short Ram Intake for 2008-2012 Honda Civic (K24/FG4)

What it Does: Replaces the restrictive factory air box and corrugated rubber tubing with a high-velocity aluminum mandrel-bent induction system to lower intake air temperatures (IAT) and increase oxygen density.

The Stock Civic Induction Weakness

The OEM intake system on the Honda 2.4L power plant is engineered primarily for NVH (Noise, Vibration, and Harshness) reduction rather than volumetric efficiency. The factory plastic housing and accordion-style intake hose create significant internal turbulence, disrupting laminar airflow into the throttle body. Furthermore, the stock enclosure is highly susceptible to heat soak during prolonged operation, causing the ECU to retard ignition timing as intake temperatures rise, which directly results in a loss of torque and sluggish throttle response.

The Engineering Solution

This short ram induction kit utilizes 6061 aluminum alloy piping, known for its superior thermal dissipation and lightweight properties. The mandrel-bent design ensures a constant diameter throughout the intake tract, eliminating the pressure drops associated with the stock restrictive curves. By utilizing a high-surface-area, washable cone filter, the system increases total CFM (Cubic Feet per Minute) capacity, allowing the K24 engine to breathe more freely during high-RPM transitions. This modification yields a documented increase of 7-10% in horsepower and 6-8% in torque by optimizing the air-to-fuel charge and providing a more aggressive, deep induction note under load.
