This Silicone Boost/Vacuum hose is perfect for a variety of applications.

-Replace any rubber hose in your engine bay

-Installation of aftermarket accessories such as a boost gauge or BOV

-Improve the appearance of your engine bay

BE AWARE! Most aftermarket silicone boost/vac hose does not work because it's thin wall and collapses under vacuum causing a wide variety of problems including incorrect gauge readings, poor running engines, false MAP signals, etc. 

It took us a lot of work to get this custom thick wall hose made to our specs that provides increased resistance to collapsing under vacuum while still having all of the other benefits of silicone.

Thick walls are more resistant to puncture, cut, and rubbing damage.

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.

Fitment:

3mm (1/8") ID / 9mm OD fits original PiMP, though we sell specific hose for this application elsewhere. 

4mm (5/32") ID / 12mm OD is a tight fit on our Blow Off Valves and Boost Controllers (Manual & Electronic). 

6mm (1/4") ID / 14mm OD will also work on the Boost Controllers and BOV's but will certainly need clamped. It also works on external wastegates though so if you're hooking up all of these items, this may be best to avoid needing adapter fittings of different sizes.

8mm (5/16") ID / 14mm OD Coming Soon?

10mm (3/8") ID / 16mm OD will fit the larger ports on most vacuum trees and intake manifolds, and is typically the size that goes from the intake manifold or throttle body to the vacuum tree, as well as the vacuum tree to the brake boost. It will also fit the large ports on our billet vacuum tree. 

FITMENT NOTE: This hose is very flexible and expands over barbed fittings well so the 4mm hose for instance will stretch over a 6mm barb fitting. So if you're connecting a 4mm port on your vacuum tree to a wastegate with a 6mm barb fitting, using 4mm hose allows it to work without any adapters while using 6mm hose would require an adapter to get it down to 4mm on one end. 

Sold by the foot - if you order 10 of these, we will ship you a continuous 10-foot length of hose.

Our silicone hose is temperature rated to 392 degrees F, and pressure-rated to 43.5 psi at that 392-degree temperature.

You are purchasing this per foot. So if you want 10 ft, make the quantity 10, if you want 25 ft, make the quantity 25, etc.
