Auxiliary air hose for Porsche 911 3.0 SC K-Jetronic hose line

Brittle or cracked rubber parts in the intake manifold or intake manifold area are often the reason for rough engine running. Especially at idle speed, the engine often does not run smoothly if it can draw in the wrong air due to aged and hardened rubber parts.
For this reason, sleeves, intermediate flanges, hoses and intake manifolds should be replaced at the first sign of ageing.
Replacing rubber parts is standard for full restorations.
Here you can get a high-quality replacement.
