The best carbon accessory in this collection is its single listed part: the CS-Style Carbon Fiber Hood Scoop Duct for the VAB WRX and STI, listed for 15-21 in the product title. If you own a 2015-2021 WRX or STI and want a carbon fiber scoop duct, this Rexpeed piece is the option this collection is built around, so check your year and model before ordering.
On the VAB WRX and STI, the hood scoop is functional, not decorative: it feeds air toward the top-mount intercooler, and the duct around the scoop opening helps manage how that air is directed. A carbon fiber scoop duct replaces the look of the factory surround with a lighter-weight composite piece and a visible carbon finish, so it is both an appearance upgrade and a like-for-like duct replacement in the same location. When you shop carbon accessories, look at the finish and weave in the product photos, confirm the part is made for your exact scoop opening, and plan for careful handling during fitting, since carbon panels reward patience around their edges and mounting points.

Rexpeed is the brand behind the part listed here, and its catalog is known for carbon fiber aero and trim pieces for Japanese performance cars, including the WRX and STI. That focus shows in this collection: a CS-style scoop duct is a niche, model-specific carbon piece rather than a universal trim item, which is exactly the kind of part Rexpeed builds its range around. See the full brand range in the Rexpeed collection, and treat the product listing as the source of truth for finish and included hardware.
Two more carbon brands are worth knowing here. Seibon is known for carbon fiber hoods, trunks, and body panels, and it is a common next step for owners who start with a small carbon accent and later move to larger panels. VIS Racing also concentrates on carbon fiber and composite body parts, offering another route for hoods and exterior panels on Japanese performance cars. Round out the exterior with Exterior Trim and the 2015+ WRX/STI range, and read our post on carbon fiber hoods and trunks before committing to larger panels.
Which cars does this hood scoop duct fit?
The product title names the VAB WRX and STI and lists 15-21, covering the 2015-2021 generation. Check your year and model and confirm your car has the matching factory scoop opening before ordering.
Is the hood scoop on the WRX and STI functional?
Yes — on this generation the scoop feeds air toward the top-mount intercooler, and the duct surrounds that opening. A replacement duct should preserve that path, so fitment to the correct opening matters more than appearance alone.
How difficult is it to install a carbon scoop duct?
It is a trim-level job rather than engine work, but carbon fiber should be handled carefully around its edges and mounting points. Follow the product instructions, test-fit before final tightening, and avoid forcing the piece into place.
How do I care for carbon fiber trim?
Wash it like painted bodywork with mild products, avoid harsh abrasives, and check the mounting points periodically.
