It took us some time to find a way to deliver a boost/vacuum hose that lives up to our high quality requirements. Most aftermarket silicone boost/vacuum hose that you can buy is too thin to carry vacuum! It will collapse under vacuum causing a wide array of problems, including high emissions, incorrect gauge readings, poor gas mileage, and possibly even engine stalling. Finally, we are able to deliver this super high quality silicone boost/vacuum hose with extra-thick walls, providing increased resistance to collapsing under vacuum.
Each kit includes:
- 10 ft - 4mm Black Silicone Boost/Vacuum Hose
- 8 ft - 6mm Black Silicone Boost/Vacuum Hose
- 4 ft - 8mm Black Silicone Boost/Vacuum Hose
- 4 ft - 10mm Black Silicone Boost/Vacuum Hose
Choose from black, blue, or red hose.
Suitable for most Subaru cars.
