Upgrade your Curl Control Kit to Grow with your Mods:

Already own a Curl Control cold air intake but need a new throttle body coupler to convert the kit to work with a different throttle body or intake manifold? We've got you covered! These are the same couplers that are supplied in our Curl Control kits, just sold separately. All couplers are made from 5-plies of woven polyester reinforcements and 6-plies of silicone for excellent rigidity and strength. Each coupler also has an integral 6061-T6 aluminum barb for connection to the valve cover breather. The CURL CONTROL silicone couplers are designed with reliefs where they connect to the throttle body, carbon tubing, and velocity stack to provide a smoother transition as air enters and exits the intake. This coupler allows use of the CURL CONTROL intake with an RBC or similar intake manifold and ZDX or similar throttle body.
