A Charge Air Hose (also known as a Turbo Hose or Intercooler Hose) is a critical component in turbocharged engines. It carries compressed air from the turbocharger to the intercooler, and then to the intake manifold. Its purpose is to deliver high-pressure, cooled air for optimal combustion, improving engine performance, fuel efficiency, and power output.
Common symptoms of a failing or leaking charge air hose include:
Loss of engine power or boost pressure
Whistling or hissing noise during acceleration
Black smoke from the exhaust
Check Engine Light (CEL) or Boost Pressure Fault Codes (P0299, etc.)
Reduced fuel efficiency
A cracked, loose, or collapsed hose can cause air leaks, reducing turbo efficiency and engine performance.
To ensure a perfect fit, verify:
OEM part number (printed on the original hose or found via VIN lookup)
Vehicle make, model, year, and engine code
Connection type (clip-on, clamp, or quick-connect)
Position: Turbo to intercooler, intercooler to intake, or turbo outlet
If you’re unsure, contact us with your VIN or chassis number, and our team will confirm compatibility.
Charge air hoses are typically made from reinforced rubber, EPDM, or silicone, often layered with textile or wire reinforcement to withstand high pressure (up to 2 bar) and temperatures (up to 200°C).
EPDM Rubber: Excellent heat and oil resistance (OEM-grade).
Silicone: Ideal for performance and aftermarket upgrades (high flexibility).
Material choice affects durability, boost pressure retention, and resistance to oil vapors.
Yes. A leaking or collapsed charge air hose can cause:
Turbocharger over-spooling (increased wear)
Incorrect air-fuel mixture, leading to poor combustion
Increased exhaust emissions
Overheating of engine components
Addressing leaks promptly prevents turbo and intercooler damage and maintains fuel efficiency.
Yes. Our Charge Air Hoses are manufactured to OEM specifications, ensuring exact fitment, proper sealing, and long service life. Each hose is pressure-tested and heat-resistant to handle turbocharged systems.
Depending on the model, hoses may include factory-style clamps or connectors. All products are covered by a warranty against manufacturing defects.
