A blown intercooler boot can quite literally ruin your day, leaving you stranded on the side of the highway. Whether you are replacing a cracked or blown boot, or just looking to add some insurance against it happening, this direct replacement hose is a great upgrade from the flimsy stock rubber boots. Due to the silicone construction, this boot will not only withstand years of abuse on a truck producing factory spec boost levels, but also on heavily modified trucks. This 2-1/2" ID x 5" long hose is used in four locations on the intercooled 1st Gen Cummins, making its application very universal. These are a great replacement for your brittle stock hoses and will withstand significantly more boost, providing years of trouble free service! Available in a glossy black, and with or without spring loaded clamps.
