Grand Rock - Silicone Charge Cooler or Heater Hose - Blue (Cold Side) or Red (Hot Side) @ 4" x 6"
Grand Rock - Silicone Charge Cooler or Heater Hose - Blue (Cold Side) or Red (Hot Side) @ 4" x 6"
This 4" x 6" blue or red silicone charge cooler or heater hose from Grand Rock is designed for cold-side charge air cooler (CAC) systems or hot-side charge air heater in turbocharged diesel and heavy-duty truck engines. It connects intercooler piping components and allows cooled compressed air to flow efficiently from the charge air cooler to the intake system, helping maintain proper engine performance and boost pressure.
Manufactured from high-temperature reinforced silicone, this hose is built to withstand the demanding conditions found in commercial truck and performance diesel applications. The flexible design helps absorb vibration, accommodate slight misalignment between pipes, and maintain a secure seal in the charge air system. High-quality silicone construction also offers excellent resistance to heat, ozone, and environmental exposure commonly found in engine compartments.
With a 4-inch inside diameter and 6-inch length, this hose fits many heavy-duty truck charge air cooler systems and is commonly used on semi-trucks, diesel pickups, and custom turbo or intercooler piping setups.
