Turbocharger Air Hose OE 31319741 Intercooler Air Hose for Volvo
The Turbocharger Air Hose / Intercooler Air Hose (OE Number: 31319741) is a critical component of the forced-induction system exclusively engineered for select Volvo models, including the V40 series and other compatible variants. It serves as a high-performance conduit, transferring compressed air from the turbocharger to the intercooler (or directly to the engine intake, depending on the system layout) while withstanding extreme under-hood conditions.
Constructed from a premium NBR-CR (Nitrile Butadiene Rubber-Chloroprene Rubber) blend reinforced with Kevlar fibers, this OE-grade hose balances exceptional flexibility, pressure resistance, and thermal stability. Unlike generic aftermarket hoses, it adheres to Volvo’s strict engineering standards—its inner diameter, length, and connection interfaces are precision-molded to match the original turbocharger/intercooler assembly, ensuring zero air leakage and optimal airflow. The Kevlar reinforcement enhances tensile strength, preventing ballooning or bursting under high boost pressure (up to 20 PSI, typical for Volvo’s turbocharged engines), while the NBR-CR rubber resists degradation from oil, heat, and road contaminants.
Core Functions
Optimized Air Transfer: Delivers compressed, high-temperature air from the turbocharger to the intercooler (for cooling) or engine intake with minimal airflow restriction. This ensures the engine receives a consistent supply of dense, oxygen-rich air—critical for maintaining turbocharged performance, fuel efficiency, and reducing emissions.
Pressure & Heat Resistance: Withstands the high boost pressure generated by the turbocharger (up to 20 PSI) and extreme under-hood temperatures (ranging from -40°C to 150°C). The Kevlar reinforcement prevents the hose from expanding (ballooning) under pressure, while the NBR-CR rubber resists hardening, cracking, or melting from heat exposure.
Leak Prevention: Features precision-molded connection ends that mate seamlessly with Volvo’s original turbocharger and intercooler ports. When paired with factory-style clamps (recommended for installation), it creates an airtight seal—avoiding compressed air leakage (which reduces turbo boost, engine power, and fuel efficiency) and preventing unfiltered air from entering the intake system.
Contaminant Resistance: The NBR-CR rubber blend repels engine oil, coolant, and road debris—common contaminants that degrade generic hoses. This preserves the hose’s structural integrity and performance over time, extending its service life.
Compatible Vehicles
This Turbocharger Air Hose / Intercooler Air Hose (OE: 31319741) is primarily tailored for Volvo V40 series models, with confirmed compatibility for the following variants and years . It also fits additional Volvo models as specified by factory engineering:
Model
Applicable Years
Volvo V40 (13-)
2013–2015
Volvo V40 Cross Country
2013–2015
Volvo S40 II
All production years
Volvo V50
All production years
Volvo C70 II
All production years
Volvo C30
All production years
Note: “V40 (13-)” denotes V40 base models launched from 2013 onward. For 100% fitment accuracy, confirm compatibility with your vehicle’s VIN (Vehicle Identification Number) or Volvo’s official service manual—this accounts for engine-specific turbocharger configurations (e.g., 1.6L vs. 2.0L turbo engines) and regional powertrain variations.
Frequently Asked Questions
