Unleash the high-revving potential of your Civic Si with a precision-engineered Cold Air Intake System designed specifically for the 2012–2015 2.4L DOHC i-VTEC engine. This system is built to dramatically improve airflow, throttle response, and overall engine performance—while adding that aggressive intake growl every enthusiast craves.

Unlike stock airboxes that draw in warmer air from inside the engine bay, this cold air intake relocates the filter to a cooler location in the fender well area. By delivering colder, denser air to the engine, it increases the oxygen available for combustion. The result is a more powerful explosion in the cylinder, translating into increased horsepower and torque—especially in the high-RPM range where the K24 engine comes alive.

But this intake doesn’t stop at just cooler air. Its inlet pipe is carefully tuned in length and diameter to optimize the resonance and air velocity for the Civic Si’s naturally aspirated setup. This 'air tuning' helps the engine breathe more efficiently throughout the RPM band, maximizing power gains without sacrificing drivability or low-end torque.
