After many requests, PRL Motorsports is proud to bring you this Cold Air Intake system that is designed to work with our RBC intake manifold adapter on the 2012 Civic SI. This intake system is made in house from 3.5″ mandrel bent 6061 tubing and utitilizes a blox racing 3.5″ velocity stack with high flow filter. The couplers are 4 ply silicone and use the correct size reducer for either the stock throttle body or the ZDX throttle body. Also included in this kit is a 1.25″ aluminum elbow that installs into the stock upper radiator hose to relocate it further down and underneath the intake to allow for better clearance and move some heat away from the intake.
When ordering, please make sure to select the proper throttle body coupler.
