Here at HPSI, we have been selling vehicle specific silicone vacuum hose kits since 1999. We focus on making the best silicone hose kits and intakes on the market. When considering temperature range, ability to handle pressure and vacuum, bend radius, appearance and other factors, we think our hoses are the best. Notice that due to our vacuum hose's superior wall strength and sizing in most cases they do not require clamps, not even on the pressure side of a forced induction car. This keeps the installation neat and makes servicing easier. Most other companies vacuum hoses need plastic zip ties to stay on.
We sell hoses on our web site & through various distributors. Chances are that if you see superb, high quality silicone products at a retailers shop or store, we manufacture it. On top of that, our return/exchange policy is the best in the business. All our silicone has a limited lifetime warranty, and will last the life of your car. OUR GUARANTEE: If any of our silicone hose fails for any reason, we will replace it at no charge to you.
We appreciate your business, and please let us know if there's anyway we can help you.
