Show original supplier description
The K-Tuned 8th Gen Cold Air Intake is a diverse and customizable intake system engineered for the 8th Gen Civic Si. It offers flexibility by allowing easy switching between Short Ram and Cold Air configurations to match your specific setup and driving conditions. This particular part number, KTD-CA8-30F, features 3-inch piping and includes a regular filter. The system includes a throttle body velocity coupler for a perfect transition from the piping to the throttle body, accommodating stock, J35, or ZDX throttle bodies. For those using the 3.5-inch pipe option (sold separately), a MAP-based tune and Flashpro are required. A special K24 Upper Radiator Hose is included to reposition the upper hose downward, and a custom battery tray is designed to lower the battery to the frame rail, creating additional space for installation. All necessary hardware and clamps are provided. Important fitment notes: This intake is designed exclusively for SI models and is not compatible with R18 engines. The V-Stack filter option on the Cold Air Intake configuration will not fit with fog lights due to insufficient clearance behind the bumper. This product is an upgrade piece and not a complete kit.
