REDOX Silicone Oil Breather Hose Kit Ferrari 348 TB TS GTB GTS Spider

Definition and Technical Specifications

The REDOX breather hose kit for Ferrari 348 provides a complete solution for replacing crankcase ventilation hoses. These high-performance silicone hoses are specifically designed for the dry sump lubrication system equipping all Ferrari 348 models.

The Ferrari 348's V8 3.4L engine uses a dry sump system requiring an efficient ventilation circuit to evacuate oil vapors and maintain optimal crankcase pressure. Original rubber hoses deteriorate over time and high temperatures, compromising system efficiency.

This REDOX kit completely replaces the crankcase ventilation hoses, ensuring perfect sealing and superior resistance to extreme temperatures (from -50°C to +200°C). The high-quality silicone used guarantees exceptional durability against oil vapors and hydrocarbons.

Each kit includes all hoses necessary for complete breather circuit replacement, precisely dimensioned according to original Ferrari specifications. Suitable hose clamps are also provided to ensure perfect installation and leak-proof connections.

Applications and Verified Compatibility

This kit is compatible with the entire Ferrari 348 range produced between 1989 and 1995:

Ferrari 348 TB (1989-1993) - Berlinetta version equipped with Tipo F119D 300 hp engine. The configuration with transverse gearbox and longitudinal mid-rear engine requires an efficient ventilation system, particularly during sporty track use.

Ferrari 348 TS (1989-1993) - Targa version sharing the same engine architecture as the TB. The crankcase ventilation system is identical, making this kit perfectly suitable.

Ferrari 348 GTB (1993-1994) - Improved Berlinetta version with Tipo F119H 320 hp engine. Despite engine evolution, the crankcase ventilation system remains compatible with this hose kit.

Ferrari 348 GTS (1993-1994) - Targa version benefiting from the same improvements as the GTB. The breather system maintains the same configuration.

Ferrari 348 Spider (1993-1995) - First mid-engine Ferrari convertible since the Daytona Spider. Equipped with the Tipo F119H engine, it uses the same ventilation system as GTB/GTS.

The dry sump system equipping all 348 models implies specific constraints. Unlike traditional wet sump lubrication, oil level can only be accurately checked with engine running. The system uses an external pump maintaining constant oil flow, making proper ventilation circuit function critical to avoid crankcase overpressure.

Benefits of Permanent Stock and Fast Delivery

REDOX maintains permanent stock of this kit in French warehouses. Any order placed before 5pm is dispatched same day by GLS courier, with guaranteed delivery within 24 to 48 hours in mainland France and most European countries.

This immediate availability represents a considerable advantage for Ferrari 348 owners. Original hoses are often out of stock at official dealers, with delivery times reaching several weeks. The Ferrari distribution network does not systematically maintain these service parts in permanent stock.

For enthusiasts using their Ferrari 348 in amateur competition or track days (Ferrari Challenge events), having rapid access to reliable spare parts is essential. A crankcase ventilation problem can quickly damage the engine, particularly during intensive use.

The lifetime REDOX warranty covers the entire kit against any manufacturing or material defects. This exceptional warranty demonstrates the manufacturer's confidence in the quality of its high-performance silicone products.

Main Technical Characteristics

Material: Reinforced multi-layer high-performance silicone Temperature resistance: -50°C to +200°C continuous operation Chemical resistance: Compatible with engine oils, gasoline, diesel, E85 ethanol Operating pressure: Up to 1.5 bar (suitable for forced ventilation systems) Wall thickness: Reinforced according to stress zones Finish: Smooth inner surface for optimal vapor flow Clamps: Stainless steel hose clamps included for each connection Warranty: Lifetime REDOX against manufacturing defects

The silicone used in these REDOX hoses exhibits superior mechanical properties compared to original rubber. Its stable molecular structure resists degradation from ozone, UV radiation, and extreme temperature variations. Unlike rubber hoses that harden and crack over time, silicone retains its flexibility and elasticity even after years of use.

The multi-layer construction with integrated textile reinforcement prevents any risk of crushing or deformation under vacuum. The crankcase ventilation system generates variable vacuum depending on engine speed, which can reach significant values at high rpm. The hoses must absolutely maintain their flow cross-section to guarantee optimal ventilation throughput.

Inner diameters are precisely machined to correspond exactly to Ferrari Tipo F119 engine fittings. No adapter is necessary, installation is performed as direct replacement of original hoses. This perfect compatibility guarantees absence of leaks and optimal ventilation system function.

Frequently Asked Questions

Q1: Is this kit suitable for my Ferrari 348 Challenge prepared for competition?

Yes, this REDOX kit is perfectly suitable for Ferrari 348 Challenge and competition-prepared versions. High-performance silicone resists higher temperatures generated by an optimized engine and increased stresses from track use. Many tuners use silicone hoses for their superior reliability under extreme conditions.

Q2: What is the lifespan of these silicone hoses compared to original rubber hoses?

REDOX silicone hoses have a considerably longer lifespan than rubber hoses. While an original rubber hose may require replacement every 5 to 8 years due to hardening and cracking, silicone hoses retain their properties for 15 to 20 years or more. The lifetime REDOX warranty testifies to this exceptional longevity.

Q3: Does installation require modifications to the engine?

No, no modifications are required. This kit installs as direct replacement of original hoses. Diameters and lengths correspond exactly to Ferrari specifications. Only basic tools are required: screwdriver for clamps and possibly cutting pliers to remove old clamps. Installation can be performed by any competent mechanic or skilled DIY enthusiast.

Q4: Can these hoses withstand intensive track use?

Absolutely. REDOX silicone hoses are designed to resist extreme stresses from track use. They handle without problem rapid temperature variations, significant vibrations, and prolonged high engine speeds. Their resistance to +200°C continuous operation offers a comfortable safety margin even under most demanding conditions.

Q5: How can I tell if my current hoses need replacement?

Visually inspect your breather hoses. If you observe cracks, rubber hardening, significant discoloration, or if the hoses have become stiff and brittle to touch, replacement is necessary. An oil leak at connections may also indicate faulty hoses. On an original Ferrari 348, preventive replacement is recommended after 10 years of age.

Q6: Does the kit include all necessary hose clamps?

Yes, the REDOX kit includes all necessary stainless steel hose clamps for complete installation. These clamps are specifically sized to guarantee optimal clamping without risk of silicone damage. It is recommended to use the supplied clamps rather than reuse old clamps.

Q7: Are these hoses compatible with modern synthetic engine oils?

Yes, REDOX silicone is compatible with all engine oils, whether mineral, semi-synthetic, or fully synthetic. It also resists modern additives contained in high-performance oils. This universal compatibility allows use of your oil of choice without any restriction.

Q8: Can I install this kit myself or should I go to a Ferrari specialist?

If you possess basic mechanical skills and suitable tools, you can install this kit yourself. The procedure is relatively simple: remove old hoses, clean fittings, install new hoses with supplied clamps. However, if you are not comfortable with this type of intervention, it is preferable to entrust installation to an experienced mechanic or Ferrari specialist.
