Intercooler Pipe
A metal or reinforced rubber pipe that channels pressurized intake air between the turbocharger, intercooler, and intake manifold.
An intercooler pipe (or charge pipe) is a rigid metal or high-strength reinforced silicone tube that connects the turbocharger output to the intercooler inlet, and the intercooler outlet to the engine's throttle body. These pipes channel the hot, compressed air produced by the turbocharger to be cooled by the intercooler before it enters the engine.
Because the air inside these pipes is under boost pressure (often 10 to 30+ psi), the pipes must be constructed to withstand high pressure without expanding or bursting. The connections are secured with heavy-duty T-bolt clamps and flexible silicone couplers to accommodate engine movement.
If a pipe cracks or a coupler blows off under boost, it creates a massive boost leak. This causes a sudden loss of engine power, a loud rushing air noise under acceleration, black smoke from the exhaust (in diesels), and a check engine light. Mechanics inspect these pipes for cracks, soft rubber spots, and secure clamps to prevent boost leaks.
