That doesn't make sense even.
No other purpose that that? If that's the case there's another POS I had to pay for, like OnStar, don't want it, don't use it, but I bought it. These cars would be cheaper if they would just sell you what you want. And I know all of them do it. Rant over. Sorry |

And second, sad but true, that is the sound tube's sole purpose. Some car manufacturers are sending engine sound into the cabin with the vehicle speakers. --KLG--

Any reason why I shouldn't just plug the tube coming out of the air intake tube?

you have to make sure the plug cant get sucked into the engine. unless your removing the hole thing theres no reason to do anything. I removed mine to put a catch can in.

I thought the whole point was to quiet down the interior noise. How would the sound tube prevent you from installing a catch can?

I get it.
What does the line from the CC do going to the intake tube? Just curious. |

its a dual exit port.
from Elites sight Q: Do I need a Single Exit Catch Can or a Dual Exit Catch Can? A: You have decided on our E2 or E2-X Catch Can, so the only option is the Single EXIT or the Dual EXIT Catch Can. On a NA engine, during acceleration, the intake manifold vacuum is used as the suction source to evacuate the damaging compounds entering as blow-by from the crankcase before they can settle and mix with the oil. But, when you accelerate, that vacuum drops to zero and no evacuation takes place. It is during these periods that the water, raw fuel, sulfuric acid, and abrasive soot, carbon, and ash particles settle and mix with the oil, and these cause the wear to the engine. The Dual Catch Can (second Exit fitting) is used to tap into an alternate evacuation suction source. This source is typically at a location just in front, or upstream of the throttle body. Note: If you do choose to install the Dual Exit (second Exit Port), you will be required to drill into your existing intake tube and insert a hose barb fitting. In addition, we use one-way inline checkvalves to open and close, to always default to the strongest suction source at the time. This provides full time crankcase evacuation instead of only when not accelerating or at wide open throttle (WOT) when no vacuum is present. Additional comment: Why does the vacuum drop to zero at WOT? The cam lobes all have overlap. That overlap is when the exhaust valve has not fully closed and the intake valve is starting to open (and vice versa). This allows reversion pulses to travel back up each intake runner and these cancel the vacuum present. This is also the period when pressure builds in the crankcase seeking the path of least resistance, which is backwards through the clean, or fresh side of the PCV system pushing oil and contaminate laden vapors into your main intake air tube assy.

Thanks for the explanation. It makes sense.
I just put a 7/8" rubber plug in the plastic 90 at the air intake. I just don't want any extra noise in the cabin. |

Little tip for installing that 2.0T firewall plugl. I originally thought the foam gasket was a little too thick on mine when i compared it to the sound tube one. But actually just putting some water on the foam to slick it up really helps it rotate.

made an improved design of DIYguy's V8 intake plug, which paired well with his firewall plug.
fits tight, without sealant. the plug is designed to tighten up if it starts to get pushed/pulled out. you will need to cut off the 3mm alignment cube on the neck of the intake hose. https://www.thingiverse.com/thing:4631376 before i started yanking anything out, i unhooked the end at the firewall so i could listen to the sound it was contributing.

I don't have a V8, so when designing it I had to rely upon the dimensions provided from another forum member who does have one. Your version looks very nice. Thanks for creating it. My V6 manifold tube plugs however fit nicely and do not loosen up. I have had the threaded version on my car for a very long time and stopped bothering to check it a while back because it just never changes. The difference of course is that the V6 has a hard(er) plastic entry fitting that will very easily split if you apply internal pressure to it. So it is necessary to use silicone RTV as the sealant and gently tighten them to avoid splitting the tube fitting. The V8 intake tube is clearly more forgiving in that regard.
