VTT Silicone Intakes
Have not seen these on here reviewed so just putting my experience for data.
I just installed these yesterday. They are considerably larger in diameter from the stock plastic tubing. This just replaces that tubing. Comes with its own hardware so that was nice, feels like its quality billet aluminum for the ends that go onto the turbo inlet. I have not measured IATs just yet, will do so soon. This is paired with K&N drop in filters. There are no whooshing sounds like you would get with after market intakes that have cone filters (in bay or front mount). I am ok with that.

So this is a closed box system with larger pipes correct. Plus the drop in filters.. 😎 I have no faith in the open filter ones unless they are way up front of the car. Inside the engine bay they just suck hot air. 🔥

There is an option for new box tops in carbon, but they’re a bit overpriced for what you get. In all honesty, the hoses and filters is enough for most people’s use and it keeps things stock looking and also still utilizes the colder front pickups the stock boxes already have in them. If you wanna get rid of the smaller and accordiony stock tubes, these are a good and inexpensive option in my opinion. Reinforced multilayered silicone intake tubes always work really well for pretty much any car, if you’re looking to keep stock box (if it’s efficient enough and flows well with even minor mods to it) as a solution.

How much of a power gain would these be had over the stock piping?
I'm hoping it would gain at least 20HP on upgraded turbos, BMC filters and e40 custom tune or am I wishfully thinking?

Kinda like replacing downpipes/midpipes - hope for decent power gains. Just not sure how much. |

I might try it out to see if it actually feels faster on the butt dyno

Do you feel any additional power increase and/or throttle response after installing it?

Bringing this back from the dead…..
Any feedback on whether it makes the car sound nicer vs stock piping (which is shit plastic, but not quite as bad as VW/Audi). Since they are bigger, should improve flow. But can the butt dyno tell? |

not sure if the difference is enough for you to notice it

Two more questions for people who know better:
1. How long do these last? Is there a possibility that they would crack at some point? 2. I read on the VTT site that these are impregnated with metal springs, so they shouldn’t collapse. Can they collapse? I would think under some type of extreme stress, but I can’t come up with a scenario. |

To address your concern, yes, they will fail someday, just like every other part on your car. However, under normal conditions, these are built to outlast your ownership of the car by many years.

In terms of collapsing, any time you have a silicone hose in the part of the intake setup that is on the vacuum side of the system, you need to make sure it’s wire/metal reinforced and with strong gauge. If it’s not, the instant air velocity increases through it and a restriction is introduced at the end of the tube (be it a physical open restriction or a plugged up filter) it will collapse on itself. It’s like a straw… if you cover one end and suck on it, the straw collapses. When the turbos really spool up and draw air in through those intake tubes, you wanna make sure they won’t collapse. FYI, if these were built without any reinforcement, even without a filter restriction, collapsing would be evident to some extent. If it was NA, maybe you could get away with a multi-walled (more plys) design, but with FI where a lot of vacuum force is exerted on the intake tubes, they definitely need the wire reinforcement. |
