• Porsche 997 MKII GT3 / GT3 RS 2010-11  

Designed to replace hard-to-source original intake components, these ducts provide large air openings that can be connected to additional brake cooling hoses, helping direct fresh air towards the braking system.

Manufactured from glass-fibre-reinforced Polyamide 6, the kit offers a lightweight, temperature-resistant solution for motorsport-inspired Porsche builds.

What Does It Do?

The air ducts capture airflow entering the front bumper and provide connection points for additional brake cooling ducting.

When connected to suitable hoses, they can help channel fresh air towards the brake assemblies, supporting heat management during demanding driving.

Why Upgrade?

Repeated heavy braking generates considerable heat, particularly during track use.

Additional brake cooling airflow can help:

• Manage brake temperatures during repeated braking
• Reduce the risk of heat-related brake fade
• Support more consistent braking performance
• Improve airflow routing towards the brakes
• Restore the appearance of GT3 RS / Cup-style bumper intakes

Actual cooling improvements depend on the completed ducting installation and have not been independently tested by the manufacturer.

Construction & Design

The ducts are reverse-engineered reproductions of an original component that is no longer readily available.

They are manufactured using a modern additive process and glass-fibre-reinforced Polyamide 6 for strength and temperature resistance.

Two versions are available:

• Without Indicator – Plain brake cooling intake
• With Indicator – Includes a smoked indicator lens and orange bulb

The indicator version requires connection to the vehicle's wiring harness.

Installation Notes

The kit is supplied without mounting hardware. A suitable fixing method must be fabricated, and the ducts require surface preparation and painting.

Additional brake cooling hoses and associated fittings are required for a complete functional cooling installation.
