People always ask us why it took us so long to add boost/vacuum hose to our product lineup. Well the answer is simple:


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.

Our Silicone Boost/Vacuum hose has extra thick walls to prevent collapsing under vacuum.
Thicker walls also make our hoses more resistant to nicks and cuts.
Smooth, slick, shiny and easy to clean, this is show quality hose.
Substantially more resistant to cracking or fading than regular rubber engine bay hoses.
Higher heat and chemical resistance than regular rubber engine bay hoses.
Sold by the foot - if you order 10 of these, we will ship you a continuous 10-foot length of hose.
