SET OF 2
We strongly recommend replacing coil springs in pairs.
Fits:
Porsche 997.1 C2 / C2S Coupe 2005 - 2008
* cars with "PASM" electronic damper control (option code: 475)
Porsche 997.1 C4 / C4S Coupe 2005 - 2008
* cars with "PASM" electronic damper control (option code: 475)
Diagram ref no 6
This spring set supports the axle load and manages suspension movement during braking, acceleration, and cornering. Replacing both springs together ensures even load distribution, symmetrical ride height, and predictable handling characteristics.
Installed within the suspension assembly, the coil springs compress and rebound with suspension travel to absorb road impacts and stabilise the vehicle body. Working together as a matched pair, they help maintain consistent tyre contact, steering precision, and ride comfort.
Coil springs weaken and sag over time due to constant load, mileage, and road conditions. Replacing only one spring can result in uneven ride height and compromised handling. Installing a pair restores correct suspension geometry, factory stance, and predictable driving dynamics.
When to replace:
• Ride height has sagged or become uneven
• Springs show fatigue, corrosion, or damage
• During shock or strut replacement
• Suspension refurbishment or alignment correction
• Reduced handling precision or ride comfort

Diagram ref no 6
This coil spring supports one side of the vehicle’s suspension, managing compression and rebound during braking, acceleration, and cornering. It helps maintain proper ride height and contributes to stable, balanced handling.
Installed within the suspension assembly, the spring compresses and expands with suspension travel to absorb road impacts and control body movement. Correct spring performance is essential for maintaining suspension geometry, steering accuracy, and ride comfort.
Over time, coil springs can weaken or sag due to constant load, mileage, and road conditions. A worn spring can alter ride height and suspension geometry, negatively affecting handling and tyre wear. Replacing tired springs with new components restores factory-style suspension balance and driving confidence.
When to replace:
• Ride height has sagged or become uneven
• Springs show fatigue, corrosion, or damage
• During shock or strut replacement
• Suspension refurbishment or alignment correction
• Reduced handling precision or ride comfort

- Porsche 928 4.5L 1978-82
- Porsche 928S 4.7L 1981-83
An OE-Match air intake rubber sleeve set, consisting of eight identical sleeves, engineered to replicate the fit, function, and durability of the original Porsche intake connectors. It seals and connects intake system components.
SET OF 8
Fits:
Porsche 928 4.5L 1978 - 1979
* with Engine type: 2801
Porsche 928 4.7L 1983 - 1984
* with Engine type: 2819, 2820 * USA, Canada, Japan models Only
Diagram ref no 37
These sleeves connect and seal intake components, preventing unmetered air from entering the engine. By renewing all connection points at once, the set helps maintain proper air-fuel mixture control, smooth throttle response, and reliable engine operation.
Installed between intake air distributor and intake manifolds, the rubber sleeves provide flexible, airtight connections while absorbing vibration and minor engine movement. Working together as a complete set, they eliminate common vacuum leaks that can lead to rough idle, hesitation, or lean-running conditions in the Porsche 928.
Aging intake rubber can crack, harden, or split from heat and oil vapours, leading to air leaks and unstable engine running. Replacing worn sleeves restores proper sealing, helping maintain correct airflow measurement and drivability.
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

This kit is comprised of the following items:
- Porsche 911 1978-1983 3.0L / SC
An OE-Match air intake rubber sleeve set, consisting of six identical sleeves, engineered to replicate the fit, function, and durability of the original Porsche intake couplers fitted to the 911 SC. It seals and connects intake system components.
SET OF 6
Fits:
Porsche 911 SC 1978 - 1983
Diagram ref no 10
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
