Description

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 OEM (stock) throttle body.

Emma N. ★★★★★

The integrated aluminum barb for the valve cover vent is a nice touch—it saved me from buying a separate fitting. Bolted right up to my RBC manifold with zero clearance issues, and the 5-ply silicone feels like it'll outlast the car.

William ★★★★★

Wasn't sure the barb would clear my valve cover vent hose, but it lines up perfectly and the hose slides right on. The 5-ply silicone is noticeably thicker than the cheap coupler I had before, so it doesn't flex under boost. Solid piece.

Zoe ★★★★★

Snug fit over the RBC manifold with no trimming needed, and the 5-ply silicone holds boost without flexing. That little aluminum barb for the valve cover vent is a smart touch too.
