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
Q: How to determine if the bumper bracket needs replacement?
A: Signs of a failing bumper bracket include visible damage or
deformation, misaligned bumper panels, unusual noises from the
front end, or if the bumper appears loose or sagging on one side.
Q: What should be paid attention to when replacing the bumper
bracket?
A: For optimal results, we recommend professional installation. Key
considerations include ensuring proper alignment of all mounting
points, checking for additional damaged components, and verifying
all fasteners are properly torqued to specification.
