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.

aftermarket boost/vacuum hose
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.

Comments about 4mm Blue Silicone Boost/Vacuum Hose Per Ft.:
This was a fantastic find. A few of the rubber vacuum lines in my old beater 1990 GMC G2500 were brittle, one had disconnected completely it was so badly rotted out. Replacing the lines that had failed with the 4MM silicone lines not only got rid of the horribly rough, low idle speed, but it restored function to my air vents! The vents were stuck on defrost, after I replaced the fubar'd lines I could select the rest of the vents as intended. Super happy with the quality of these hoses, plus they're blue. Wholeheartedly recommend.
BOTTOM LINE? Yes, I would recommend this to a friend Was this review helpful? Yes / No
