Womala Airflow Channel OE 31294096 Radiator Spoiler for Volvo V40 2013-2019

Core Functions

• A. Cooling System Optimization

  • Directed Airflow to Radiator: The channel’s curved, aerodynamic shape acts as a “funnel,” guiding incoming air from the front bumper directly into the radiator core. This increases the volume of cool air passing through the radiator, which is critical for dissipating heat from the engine coolant—especially during high-load scenarios (e.g., highway driving, towing, or hot weather). Without proper airflow, engine temperatures can rise, leading to overheating, reduced performance, or engine damage.
  • Condenser & Intercooler Support: For V40 models with turbocharged engines (e.g., T3, T4) or air conditioning, the channel also directs air to the intercooler (cools compressed air from the turbo) and condenser (cools refrigerant for AC). This maintains optimal intercooler efficiency (preserving turbo power) and ensures the AC system delivers cold air even in extreme heat.

  B. Aerodynamic Efficiency

  • Drag Reduction: By streamlining airflow under the front bumper, the channel minimizes turbulent air that would otherwise create drag. Turbulence increases fuel consumption by forcing the engine to work harder to maintain speed—this OE channel reduces drag coefficient (Cd) by ~0.005, a small but measurable improvement that translates to better fuel efficiency (typically 1–2% higher MPG during highway driving).
  • Airflow Separation: Prevents air from becoming trapped under the vehicle or swirling around the front wheels, which can cause wind noise and instability at high speeds. The channel’s design ensures air flows smoothly past the radiator and exits under the vehicle, reducing cabin noise and improving high-speed stability.

  C. Component Protection

  • Debris Shielding: Acts as a barrier between the radiator and road debris (e.g., stones, gravel, leaves). By directing airflow upward into the radiator (rather than allowing debris to hit the core directly), it reduces the risk of radiator fin damage—bent or broken fins block airflow and reduce cooling capacity, requiring costly radiator repairs.

 Compatible Vehicles

This Airflow Channel (OE: 31294096) is tailored exclusively for Volvo’s compact V40 lineup, including both standard and Cross Country variants. Below is a consolidated list of models and applicable years:

Notes: “V40 (13-)” denotes the second-generation V40 (launched in 2013), which shares identical front-end cooling system geometry with the V40 Cross Country. For 100% fitment accuracy—especially for models with optional cooling components (e.g., larger intercoolers for high-performance variants)—confirm compatibility with your vehicle’s VIN (Vehicle Identification Number) or Volvo’s official service manual.
