Our 4 ply, reinforced silicone charge tubes directly replace the OEM rubber boost hoses. These charge tubes are so strong that they can support over 80 PSI of boost! Each set comes with both upper and lower hoses as well as high-strength, spring loaded T-Bolt Clamps for the turbo, throttle body and both sides of the intercooler. These top quality clamps ensure a leak proof connection that absolutely will not blow off - even under extreme boost! The tubes have a 1" BOV port and an extra port for a boost gauge. In case you are not running a BOV, a billet anodized block-off plug and clamp are included as well. Not only are our charge tubes super strong and burst proof, but they add a bit of eye candy as well!
