Replace your intercooler boots or almost any other boot or hose on your rig with a set of upgraded heavy duty Silicon Hoses from PPE. PPE's Silicone Hoses are constructed using Fluorocarbon lined, silicon rubber that is strengthened with five plies of Nomex fibers. This design results in a hose that resists fuel, oil, UV, ozone, as well as various other chemicals plus it has a burst rating of over 200 psi from negative 76 degrees to 437 degrees Fahrenheit. Simply put, these will be the last hoses and boots you will ever buy. Available in various bends and straights with sizes from 2.5 inches up to 6 inches in diameter. Complete intercooler boot kits for many late-model diesel equipped vehicles are also available.
