These sleeves connect and seal individual intake components, preventing unmetered air from entering the engine. By restoring proper intake sealing across all connection points, the set helps maintain correct air-fuel mixture, smooth throttle response, and consistent engine operation.
Installed between intake runners and associated air ducting, the rubber sleeves provide a flexible, airtight connection while absorbing vibration and engine movement. Working together as a complete set, they eliminate common vacuum leaks that can cause rough idle, hesitation, or lean-running conditions on the 911 SC.
On classic Porsche engines, intake rubber components are prone to hardening, cracking, and shrinking due to age, heat, and fuel vapours. Even minor air leaks can disrupt mixture control and drivability. Replacing all intake sleeves as a complete set ensures consistent sealing across the system and helps restore proper engine performance and reliability.
When to replace:
• Visible cracks, splits, or swelling in the rubber
• Loose fitment or air leaks at the coupling points
• Rough idle, hesitation, or lean-running symptoms (after inspection)
• During intake service or when replacing adjacent intake hoses/boots
• Excessive hardening or deterioration from heat/oil exposure
