Designed for the 2012-15 Civic Si with stock manifold and throttle body. The intake requires relocating the battery in front of the transmission to the intake pipe to get behind the bumper. This kit requires the change of the factory clutch line. This can be done with our clutch line kit KTD-CLK-001 or either of our CMC kits.
