  1. Exactly what I was looking for, no more, no less 4 Star Review

    Posted by on 3rd Mar 2021

    I have a 2000 Audi A4 and I was having some issue with the turbocharger vacuum system. It turns out that the hoses weren't the issue, but I did want to refresh the hoses anyways. I replaced all of the hoses that I could use this for, and despite not having any issues from the vacuum system itself, I actually noticed that my vacuum and boost were much more consistent, so this hose has managed to help me fix a leak I didn't even know I had. It fits onto the connectors very well, and with a relatively thick wall it works well with hose clamps.

  2. Auto Vacuum line 5 Star Review

    Posted by on 5th Feb 2021

    Used the 3.5mm hose to replace the IWE Vacuum line on my Ford F-150. As anyone who owns one of these trucks may know the factory vacuum line is a cheap, thin, hard plastic. The line will quickly become very brittle and crack constantly. Ford replacement parts are the same cheap material and cost more then I spent on this silicone line.

    The silicone line itself is perfect, thickly walled and easy to work with. This should be a permanent fix for an obvious flaw in Fords design.

    Product arrived quickly, well packaged and as described. Will be using for any future vacuum line needs.

  3. They make a very good silicon hose product 5 Star Review

    Posted by on 27th Nov 2020

    I used the 3.5mm hose. It's a good product and good choice for replacing the smaller Toyota vacuum hoses. The only issue is the Black color is really more of dark gray. It was fine more my older Camry. But if you need it to match existing black silicon or rubber hoses it is going to be a concern. Be aware the hose OD is larger than the OEM so it may not fit correctly into the hose retainers as the OEM did. But its going to last a long time!

  4. Best Vacuum Hose I've come across, & at a great price! 5 Star Review

    Posted by on 26th Oct 2020

    This Vacuum Hose was not only the correct size for my application, (3.5mm,) but it installs very easily, fit into all of the plastic hose holders that "Mazda" (in my case,) used to hold all of the original hoses into place, for routing them around the engine compartment. I also noticed a difference in how my car drives because it helped correct a feeling of pulsing under acceleration, which i had been trying to figure out & fix. So, I highly recommend these Vacuum Hoses from SiliconeHose.com, because they truly are an awesome product from an awesome company!!

  5. Absolutely destroys local part stores quality! 5 Star Review

    Posted by on 9th Feb 2018

    Replaced all vacuum lines on my 1999 Audi A4 with 202k which were still STOCK and practically crumbled in my fingers upon removal. I am still waiting for a new check valve to arrive as the one already installed(which sure didn't seem stock because it was relatively clean), I could not blow any air through either way; so my system still isn't functioning completely properly, but I don't think my car is arguing with me as for the rest of it because off of my first tank I instantly noticed an improvement in MPG's. And a bonus, my BMW uses the same size tubing so I ordered more than enough to do that vehicle also when it's nice enough to come out from hiding ;)

  8. Made in USA and it shows! 5 Star Review

    Posted by on 31st Oct 2016

    Definitely a 5 star quality product. Sigficantly nicer and built to a higher standard than the import versions of silicon hose. Might be slightly more expensive but DEFNITELY worth it. Excellent customer service staff too.
