i just installed a short ram air intake on my 98 jetta, and my vacuum house and another hose are pretty much just sitting there free. now when i hit the gas (when driving, not idle) my car makes a loud growling type of noise almost like a muscle car, is this normal? or is this because those 2 hoses are unused now? ive been told to remove one and plug the vacuum but im only good at putting things together, i dont even know which one is the vacuum hose or which one to plug or remove or what.
you wont get a growling noise, get a whistling sound from the filter. if you have a exhaust, such as flowmasters the intake works really well with flowmasters muffler, giving it a deeper note.
the original air box was designed to muffle the sound you now hear and as far as telling the difference of the vacuum line to the other the one that sucks air while running is the vacuum line plug it and you should be fine.
Just put it back the way it was. Intake kits don't do nothing for you and particularly VWs are FRAGILE so I wouldnt be surprised if your motor locked up next week from that stupid crap.
