5-Piece Oil Breather Silicone Hose Kit REDOX for Citroën Visa GTI 1.6

High-Performance Silicone Hoses for Citroën Visa GTI - Oil Breather System

The 5-piece REDOX silicone hose kit completely replaces the oil breather system of your Citroën Visa GTI equipped with the 4-cylinder 1.6L XU5J (105 hp) or XU5JA (115 hp) engine. Manufactured from VMQ silicone with special inner layer for hydrocarbon resistance, these hoses offer exceptional mechanical properties against thermal and chemical stresses of the engine oil breather circuit.

Verified Technical Specifications

This kit fits perfectly all Citroën Visa GTI produced between October 1984 and September 1988, equipped with the transverse front-mounted 4-cylinder inline engine of 1580 cc. The Visa GTI shares its engine with the first-generation Peugeot 205 GTI, using the XU5J engine developing 105 horsepower from 1985 to 1986, followed by the XU5JA with 115 horsepower from September 1986. These hoses withstand extreme engine bay temperatures from -50°C to +200°C without degradation of mechanical properties.

Applications and Engine Compatibility

The hoses are specifically designed for the oil breather system of the XU5J/XU5JA engine, connecting the valve cover to the oil filler circuit and breather. This system allows evacuation of crankcase gases while preventing overpressure that could damage seals. Compatible with all 9,516 Citroën Visa GTI produced, whether the 105 hp version (approximately 7,145 units) or 115 hp version (approximately 2,371 units).

Replacement for Original Rubber Hoses

Original natural rubber hoses exhibit limited mechanical properties against chemical attacks from oil vapors and repeated thermal cycles. Rubber expands, cracks and eventually leaks, causing oil losses and vacuum leaks that disrupt engine operation. REDOX silicone hoses permanently eliminate these issues through superior chemical resistance and dimensional stability.

Permanent Stock Availability and Fast Delivery

REDOX maintains permanent stock of silicone hoses for Citroën Visa GTI in French warehouses. Any order placed before 5pm is dispatched the same day via GLS carrier, with delivery to mainland France within 24 to 48 working hours. This immediate availability avoids prolonged downtime of your collector vehicle during preventive maintenance operations.

Frequently Asked Questions (FAQ)

What is the difference between silicone and original rubber hoses? REDOX silicone hoses resist extreme temperatures (-50°C to +200°C) without hardening or cracking, unlike rubber which ages quickly. Silicone maintains its flexibility and sealing over time, even against aggressive oil vapors from the breather system.

Does this kit fit both versions of the Visa GTI? Yes, this kit fits perfectly on Citroën Visa GTI equipped with the 1.6L XU5J engine of 105 hp (1985-1986) and the XU5JA engine of 115 hp (1986-1988). Both engine variants share the same oil breather system.

Are the hose clamps included with the kit? Yes, all stainless steel hose clamps required for installation are included in the kit. The clamps are precisely sized to ensure optimal sealing of silicone hoses without risk of leakage.

How long do REDOX silicone hoses last? REDOX silicone hoses have lifetime warranty. Their exceptional chemical and thermal resistance allows them to maintain their mechanical properties throughout the vehicle's lifespan, unlike rubber hoses requiring regular replacement.

Is delivery time guaranteed even for a rare vehicle? Yes, REDOX maintains permanent stock for the Citroën Visa GTI despite its rarity (9,516 units produced). Order before 5pm = same-day dispatch, GLS delivery 24-48h to mainland France.

Can I install these silicone hoses myself? Installation is achievable for an amateur mechanic with basic tools. The hoses mount directly in place of original hoses, following the original routing of the breather system. No vehicle modification required.

Do silicone hoses improve engine performance? Silicone hoses guarantee optimal sealing of the breather system, avoiding vacuum leaks that disrupt engine operation. They maintain original performance by ensuring correct evacuation of crankcase gases without vacuum loss.

Which color should I choose for my Visa GTI? Color choice is aesthetic and does not affect performance. Red recalls the sporting GTI spirit, blue offers a modern contrast in the engine bay, black ensures total discretion close to original appearance.
