Porsche 718 Cayman/Boxster (982, 2016+) Prepreg Dry Carbon Fiber Finned Side Air Duct

Engineered for Porsche 718 Cayman/Boxster (982 chassis, 2016+) owners, this Prepreg Dry Carbon Fiber Finned Side Air Duct is the more aggressive, race-inspired finned variant of our standard 718 carbon side air duct. It gives your mid-engine sports car a motorsport identity at the side intakes while visually emphasizing airflow. Manufactured in Europe and quality-controlled by BYC Performance, this Porsche 718 finned carbon side air duct bolts directly to OEM mounting points.

If you are building a serious Porsche 718 tuning project and want a side intake trim more aggressive than both the factory plastic and the standard carbon version, this finned dry carbon side air duct is built for you. The fin geometry echoes GT-series Porsches and motorsport styling. Autoclave-cured prepreg carbon is noticeably lighter, far superior in strength, and outstanding in UV resistance.

Key Features

• Prepreg (Dry) Carbon Technology: Autoclave-cured under high heat and pressure; homogeneous resin, a more consistent weave.
• Finned Design: Multi-fin race-inspired profile; more aggressive visual impact than the standard carbon version.
• Weight Reduction: Noticeably lighter than the factory plastic part.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug and play installation on 982 Cayman and Boxster side bumper intake frames.
• Pair Set: Ships as left and right panels; symmetrical design.
• UV and Chemical Protection: Long-life clear coat protects against fading, cracking, and stone chips.

Prepreg (Dry) Carbon vs. Wet Carbon - Which Is Better?

Most aftermarket carbon parts are made using wet lay-up, where resin is applied by hand and cured at room temperature - leaving air voids and inconsistent weight. Prepreg (dry) carbon:

• Cured in an autoclave under high heat and pressure - a more consistent weave
• A controlled resin ratio - lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use
