The intake system for the 6-cylinder 981 and 982 (718) Porsche Caymans is uniquely crafted from prepreg carbon fiber and infused carbon fiber, both cured in an autoclave. This is the only complete intake system available on the market for these Porsche models.
Featuring built-in snorkels, the system facilitates air ducting from a higher point on the side of the car, resulting in lower intake temperatures, more laminar airflow, reduced turbulence, and maximized performance. Extensive testing and development have ensured this intake system delivers optimal results for your Porsche Cayman.
The system is fully reversible and requires no cutting or modification of original parts, except for trimming the plastic cover under the roll hoop. It also enhances the driving experience with a great induction noise from the engine, located right behind the driver's ears. Designed to maintain an OEM+ look, the system boasts a stunning carbon fiber appearance in various finishes, all providing excellent UV protection.
Additionally, the existing lower side ducts will now function as auxiliary air-cooling channels for the engine, similar to the GT4 RS.
Installation Process
The installation process of the RS Style Carbon Intake is straightforward and can be undertaken by professional technicians or experienced car enthusiasts. It includes a detailed installation video to ensure a smooth and hassle-free process. Following the provided guidelines carefully is essential to achieve the best results.
