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 ZDX or similar throttle body.

Zoe Z. ★★★★★

Installed this coupler over the weekend and the 5-ply silicone is noticeably more rigid than the stock rubber piece, which finally stopped my intake tube from sliding off under acceleration. The integral aluminum barb for the valve cover vent was a nice surprise, saving me a trip to the hardware sto

Charlotte ★★★★★

The 5-ply silicone feels sturdy and the integral aluminum barb made connecting the valve cover vent super clean. Fit my RBC manifold without any leaks on first try.

Samuel ★★★★☆

The 5-ply silicone feels really sturdy, and the built-in aluminum barb for the valve cover vent was a perfect fit on my RBC manifold. Took about 15 minutes to swap out the old coupler, no leaks so far. Only gripe is the price feels a tad high for a piece of hose, but it’s clearly quality.
