Renault 5 GT Turbo silicone intercooler hose kit: the end of bulging hoses
This silicone intercooler hose kit for the Renault 5 GT Turbo replaces the original rubber hoses, which have become porous after thirty years of service. On a tuned C1J turbo engine, a worn hose deforms under pressure, boost pressure drops, and acceleration becomes sluggish: braided silicone eliminates this weak point.
Why switch to silicone hoses
- Braided multilayer silicone: fabric layers prevent the hose from bulging when pressure rises.
- Temperature resistance: silicone withstands the heat of the engine bay much better than aging EPDM rubber.
- Oil and ozone resistance: no hardening or cracking after a few summers.
- Twelve colors: from discreet black to red or blue that bring a classic engine bay back to life.
- Original dimensions maintained: each hose matches the shape and diameters of the R5 GT Turbo intake system.
- Complete kit: all hoses for the boost air system, ready to install.
The R5 GT Turbo air system, link by link
On a turbo engine, the air compressed by the turbocharger passes through the air-to-air intercooler before reaching the manifold. Between each component, intake hoses provide the connection: they are the ones subjected to pressure and heat. A silicone hose is not just prettier; it maintains its cross-section under load, so the full pressure reaches the engine. It is one of the most cost-effective upgrades for a classic Renault 5 GT Turbo, along with replacing the hose clamps.

Installation and maintenance
Allow 1 to 2 hours on a cold engine. Remove one hose at a time so you never lose track of the mounting order, clean the pipe ends, and reassemble without grease. New worm-drive hose clamps are highly recommended: a new silicone hose on a worn clamp will eventually slip. Check for leaks after 50 km, then tighten if necessary. Compatibility should be checked according to the version and any modifications already present on the system before installation.
Frequently asked questions
Does silicone add power?
Not directly. It prevents the pressure loss caused by a bulging hose, so it restores the performance the engine had originally.
Should the clamps be changed at the same time?
This is strongly recommended. A loose clamp is the leading cause of a hose slipping under high pressure.
Is silicone resistant to oil vapors?
Yes for road use. If your system is connected to an oil-filled breather, plan for an oil catch can upstream.
What does custom color mean?
It is a shade outside the eleven standard colors, produced on demand. The preparation time is longer than for a color from the catalog.
Do these hoses fit an R5 Alpine Turbo?
The system differs. This kit is based on the GT Turbo dimensions: compare the lengths and diameters before ordering.
Restore the pressure your R5 GT Turbo has lost: a set of silicone hoses, two hours in the garage, and the turbo regains its responsiveness.
