The pressure pipe is manufactured in 3”; mandrel bent seamless aluminium pipe. CNC machined sensor flange for best fitment.

Custom made high quality silicone hose with 4 layers of polyester/aramid reinforcement. These hose can handle very high temperature and pressure!

Always remember that the OEM intercooler pipes and hoses was designed for the power level the car was built for and a power increase or even very hard use of the car in a standard version may cause that the OEM pipes and hoses don’t have the performance you need. So only after engine software tune do88 pressure pipes will give a performance increase over the OEM pipes!
