The K-Tuned 9th Gen Civic Si Cold Air Intake is a performance upgrade designed for 2012-2015 Civic Si models with a stock manifold. It features 3.5-inch piping to enhance airflow. Installation requires relocating the battery and may necessitate changes to the factory clutch line.
Show original supplier description
The K-Tuned 9th Gen Civic Si Cold Air Intake is engineered specifically for the 2012-2015 Honda Civic Si models equipped with the stock manifold and throttle body. Featuring 3.5-inch piping, this system is designed to optimize airflow for improved performance. Installation of this intake requires relocating the vehicle's battery to a position in front of the transmission, allowing the intake pipe to fit behind the bumper. Additionally, it is incompatible with the factory clutch line, requiring the use of an aftermarket clutch line kit such as K-Tuned's KTD-CLK-001 or one of their CMC kits. To ensure proper operation and to take full advantage of the 3.5-inch piping, a performance tune is mandatory. This includes using either Flashpro or KTuner software and switching the engine's fueling strategy to a MAP-based tune. It is important to note that this cold air intake does NOT fit R18 Engines.
