Cold Air Intake For Honda Civic (2012-2015) with 2.4L Engine Red

Stop letting your K-Series breathe through a straw; it’s time to hear that VTEC crossover the way Honda intended and reclaim the throttle response buried by factory plastic.

Performance Cold Air Intake for Honda Civic Si (K24Z7)

If you’re driving a 2012-2015 Civic Si, you know the K24Z7 is a workhorse, but the factory air box is a masterclass in compromise. Designed more for silencing the engine than for actual flow, the OEM intake system creates a bottleneck that stifles the 2.4L engine's natural aspirated potential. This Red Cold Air Intake system replaces that restrictive, heat-soaking factory box with a high-flow mandrel-bent tube and a washable performance filter, allowing your engine to pull in cooler, oxygen-rich air from outside the engine bay.

We see it on the forums constantly—owners complaining about the "rev hang" and the muted engine note of the 9th Gen Si. By streamlining the induction path, this kit helps the engine breathe more freely throughout the powerband. The result isn't just a dyno-proven gain of 7-13 HP; it’s a night-and-day difference in how the car reacts when you downshift. This kit is specifically engineered for the 2.4L K-Series architecture, ensuring that MAF sensor readings remain accurate while providing a much more aggressive, throaty induction roar when you hit the high-cam profile.

Whether you're rowing through the gears in a manual or daily driving an automatic, this upgrade provides a crispness that the stock rubber bellows simply can't match. Plus, the vibrant red finish adds a much-needed performance aesthetic to an otherwise dull engine bay.

Why You Need This Upgrade

• Substantial Power Gains: Dyno-estimated increase of 7-13 HP by reducing air intake restriction.
• VTEC Induction Sound: Transforms the muted stock tone into a deep, aggressive growl under heavy acceleration.
• Reusable Filtration: Includes a universal red washable filter, eliminating the need to buy disposable paper filters ever again.
• Improved Efficiency: Enhanced airflow allows for better throttle response and potentially improved fuel economy during cruising.
• Direct Fitment: Engineered to work with your factory warranty and original mounting points.

Installation Notes

Installation is straightforward and can be completed with basic hand tools like screwdrivers and a socket set. Pro Tip: Always disconnect your battery terminal during the install. After the intake is secured, leave the battery disconnected for a few minutes; this forces the ECU to reset and "re-learn" the new air-to-fuel trim parameters based on the increased flow. Please note: This kit is NOT compatible with vehicles equipped with throttle body spacers or aftermarket turbo kits.
