REDOX Silicone Turbo Hose Kit Alfa Romeo 156 2.4 JTD 175hp - Boost System

High-Performance Silicone Hoses for Alfa Romeo 156 2.4 JTD 175hp

This REDOX silicone hose kit replaces the original rubber hoses in the boost system of your Alfa Romeo 156 equipped with the 2.4 JTD 20-valve engine producing 175 horsepower. Designed to withstand the extreme demands of turbocharged diesel engines, these hoses guarantee reliability and sustained performance.

Advanced Technical Specifications

Manufactured from VMQ silicone (polysiloxane) with specially formulated inner layer for diesel hydrocarbon resistance, these hoses offer exceptional mechanical properties. The 4-ply construction with 5mm total thickness ensures optimal resistance to boost pressure generated by your 156's Garrett turbocharger. Unlike original rubber that expands, cracks and eventually punctures under heat and pressure effects, REDOX silicone maintains its shape and seal within the -50°C to +180°C temperature range.

Applications and Alfa Romeo 156 Compatibility

This kit is specifically developed for the Alfa Romeo 156 (type 932) equipped with the 2.4 JTD 20V inline 5-cylinder engine producing 175 horsepower (129 kW), manufactured between October 2003 and September 2005 for the sedan, and until May 2006 for the Sportwagon. The 2387 cc engine develops 385 Nm of torque at 2000 rpm, generating significant boost pressure that only high-performance hoses can handle durably.

The kit mounts on the circuit between turbocharger and intercooler, a particularly stressed area where temperatures and pressures reach their maximums. These hoses directly replace original parts, offering perfect fitment without modifications.

Replaced Alfa Romeo OEM References

This REDOX kit replaces the following Alfa Romeo manufacturer references: 60676179, main reference for upper boost circuit hoses of the 2.4 JTD. Also compatible with equivalent references 60676178, 60688599, and 60688600 depending on production years. Check the reference printed on your original hoses before ordering to guarantee exact compatibility.

Benefits of REDOX Silicone Permanent Stock

Unlike typical lead times for specific Alfa Romeo parts, REDOX maintains permanent stock of this kit. Order before 5pm, your kit ships same day via GLS courier for delivery within 24 to 48 hours across Europe. No more endless waiting for unobtainable hoses from your dealer or prohibitive prices for original parts. Our European logistics guarantee immediate availability and competitive pricing.

Why Replace Your Rubber Hoses with Silicone

Original rubber hoses on the Alfa Romeo 156 2.4 JTD are designed for economical mass production, but their limited mechanical properties inevitably cause premature degradation. Natural rubber hardens over time, loses elasticity, develops microcracks, then eventually punctures or bursts, often at the worst moment. REDOX silicone permanently eliminates these problems thanks to its exceptional chemical resistance to diesel hydrocarbons, ozone and extreme temperature variations.

Frequently Asked Questions (FAQ)

Why do my original hoses degrade so quickly? Original rubber hoses are subjected to extreme stresses: turbo heat, boost pressure, contact with oil vapors and hydrocarbons. Economical natural rubber doesn't durably resist these attacks, hence cracks and punctures after a few years.

Do silicone hoses improve engine performance? Silicone maintains constant internal diameter without expanding under pressure, unlike rubber. This optimizes airflow to the intercooler and preserves boost efficiency, particularly beneficial on an engine delivering 385 Nm torque like the 2.4 JTD.

Can I fit these hoses on a 2.4 JTD with different power output? This kit is specifically developed for the 175hp version (October 2003 to 2006). The 150hp and 163hp versions use different circuits with other references. Absolutely verify OEM reference 60676179 on your current hoses.

Which color should I choose for my hoses? The choice is purely aesthetic: blue for sporty look visible under bonnet, black to remain discreet close to original, red for racing appearance. Mechanical properties are identical regardless of color.

Are hose clamps included in the kit? No, clamps are not supplied. You can reuse your original clamps if in good condition, or opt for stainless steel aviation-type clamps for optimal clamping and maximum security.

What does the lifetime warranty cover? The REDOX lifetime warranty covers all normal road and sporting use. It doesn't cover damage resulting from incorrect fitting, insufficient clamp tightening, or extreme engine modifications far exceeding original specifications.

How long does delivery take to the UK? Order before 5pm, your kit ships same day. GLS typically delivers within 24h in mainland UK, maximum 48h for more remote areas. You receive a tracking number upon dispatch.

Do these hoses withstand engine tuning? Yes, REDOX silicone withstands pressure and temperature levels higher than original, making them compatible with moderate tuning (remapping, performance intercooler). For extreme tuning, contact us for validation.
