CAC CONNECTOR HOSE COLD SIDE 3.5X6

This is a cold-side charge air cooler (CAC) connector hose designed to connect the intercooler to the intake piping on turbocharged diesel engines. Its job is to carry cooled, compressed air from the intercooler to the engine’s intake manifold while absorbing vibration and movement between components. Over time, heat, oil contamination, and boost pressure cycles can degrade the material, leading to splits, leaks, loss of turbo pressure, and reduced fuel efficiency, so it should be replaced at the first sign of damage or swelling. Constructed from high-temperature silicone, this straight, 2-hump hose provides a durable and flexible connection for heavy-duty truck applications.
