9th Gen Civic Si 3.5-Inch Cold Air Intake

The K-Tuned 9th Gen Civic Si Cold Air Intake is a performance upgrade specifically engineered for 2012-2015 Civic Si models equipped with the stock manifold and throttle body. This intake system features 3.5-inch diameter piping to improve airflow. Installation of this cold air intake requires relocation of the vehicle's battery to the intake pipe, positioning it behind the bumper. Additionally, the factory clutch line must be modified or replaced; K-Tuned offers a compatible clutch line kit (KTD-CLK-001) or CMC kits for this purpose. To ensure optimal performance and drivability with the 3.5-inch piping, a Flashpro or KTuner tuning device is required, and the vehicle must be switched to a MAP-based tune. This intake is explicitly stated not to work with the factory clutch line and does NOT fit R18 engines. Detailed installation instructions are available.
