REDOX Silicone Turbo Intake Hose - Citroën DS3 Racing 202hp 207hp - EP6DTS Engine (2011-2015)

High-performance silicone turbo intake hose for DS3 Racing

The REDOX silicone turbo intake hose represents an essential upgrade to the intake system of your Citroën DS3 Racing equipped with the 1.6 THP EP6DTS engine producing 202 or 207 horsepower. This hose connects the air filter housing to the Twin-Scroll Borg Warner turbocharger, a critical component directly influencing turbocharged engine performance.

REDOX silicone technical specifications

Manufactured from premium VMQ silicone, this hose features a 4-ply construction with 5mm wall thickness ensuring exceptional mechanical strength. REDOX silicone withstands extreme temperatures from -50°C to +180°C, performance levels unattainable by original rubber. The multi-layer structure provides optimal rigidity eliminating deformation under boost pressure whilst maintaining necessary flexibility during installation.

Verified DS3 Racing applications

This silicone hose fits specifically Citroën DS3 Racing models produced between February 2011 and July 2015, equipped with 1.6 THP EP6DTS engine:

• DS3 Racing 202 hp (149 kW) at 6000 rpm
• DS3 Racing 207 hp in certain markets
• Engine torque: 275 Nm from 2000 to 4500 rpm
• Engine code: EP6DTS (5FF)
• Turbocharger: Twin-Scroll Borg Warner with air-to-air intercooler

The DS3 Racing, high-performance version developed by Citroën Racing, requires components capable of withstanding increased thermal and mechanical stress from the optimised turbocharged engine.

Replacing the failing original hose

The original rubber hose on the DS3 Racing presents several structural weaknesses. Natural rubber used by the manufacturer progressively degrades under repeated thermal cycles between the hot turbocharger and ambient air. This degradation manifests as surface cracks evolving into deep fissures. Loss of elasticity in ageing rubber causes excessive expansion under pressure, creating air leaks reducing effective boost pressure. In advanced cases, complete hose rupture causes total power loss and risks turbocharger damage from foreign object ingestion.

Replacement with a REDOX silicone hose permanently eliminates these issues through silicone's superior molecular stability against thermal and chemical stress.

Permanent stock and rapid delivery France and Europe

REDOX maintains permanent stock of DS3 Racing silicone hoses in its French warehouse. Orders placed before 5pm are dispatched same day throughout mainland France. Delivery occurs via GLS carrier within 24-48 hours. For Europe, a second warehouse ensures distribution within 72 hours maximum to Germany, Spain, Italy, Belgium, Netherlands and Luxembourg.

This immediate availability allows rapid replacement of a failing hose without immobilising your DS3 Racing for weeks awaiting parts.

Benefits for your DS3 Racing

Replacing the original turbo intake hose with this REDOX silicone hose brings several measurable benefits. Eliminating expansion and air leaks maintains optimal boost pressure from the Twin-Scroll turbo, preserving the 202-207 horsepower intended by Citroën Racing. Silicone's chemical resistance to hydrocarbons and oil vapours ensures durability vastly superior to original rubber, eliminating periodic replacement needs. Three available colours allow aesthetic customisation of the engine bay whilst maintaining identical mechanical properties.

Frequently asked questions

Does fitting this hose require specialist tools? No, replacement is performed with a screwdriver or spanner to loosen original clamps. The procedure takes approximately 15 minutes. Supplied stainless clamps position at the same locations as originals.

Is this silicone hose suitable for modified DS3 Racing models? Yes absolutely. REDOX silicone withstands pressures far exceeding those generated by the original turbo. DS3 Racing with engine remapping or turbo modification can use this hose safely provided pressure remains below 3 bar.

What difference between 202hp and 207hp versions for fitting? No difference for this hose. The 202 and 207 horsepower versions use the same EP6DTS engine and identical intake architecture. The hose suits both power outputs.

Does colour choice influence performance? No, all three colours (blue, black, red) share exactly the same silicone composition and identical mechanical and thermal properties. Choice remains purely aesthetic according to your preference.

What does the lifetime warranty cover? The warranty covers all manufacturing and material defects: cracks, tears, ply separation, silicone degradation. It does not cover damage caused by incorrect fitting, use outside specifications or mechanical accident.

Can this hose fit other PSA models with EP6DTS engine? The EP6DTS engine indeed equips other Peugeot and Citroën models, but hose geometry and dimensions vary according to applications. This hose is specifically designed for DS3 Racing and may differ for other vehicles despite identical engine.

Should I replace other silicone hoses simultaneously? Not mandatory but recommended if your DS3 Racing exceeds 80,000 km. The intake circuit comprises several rubber hoses ageing simultaneously. Complete replacement avoids multiple interventions at short intervals.

Does REDOX silicone resist E85 ethanol? Yes, VMQ silicone resists E85 ethanol perfectly unlike original rubber which can degrade with prolonged contact with this fuel. If you have converted your DS3 Racing to bioethanol, this silicone hose is particularly suitable.
