Is this sound normal? Does your air intake make this noise?

By TeeHizzleNizzle
- Thu May 17, 2012 10:44 pm #305276 My air intake (Not the manifold) makes a loud sucking noise. Some people have told me this isn't normal, some people said it is.

I have a Spectre short ram intake.

THIS AUDIO IS WITHOUT THE SPECTRE FILTER
The sucking noise is coming from the intake tube

I also seem to be getting only average MPG even with a short ram intake and a full exhaust and headers (Stock catalytic :roll: )

It just seemed unusually loud compared to some of my friends cars, as if there was some resistance.
What do you guys prefer , Spectre (oiled) filter or AEM (Dry flow) for performance and MPG

Thanks man, you're totally right
At first I thought the noise was just because of my filter, but the noise still occurred without the filter on

The noise is normal and will vary depending on intake pipe design.

There is no fuel mileage increase from modifying the intake or exhaust system. It's a myth that has been repeated as dogma online since the advent of car forums. Modifying a car can increase your VOLUMETRIC efficiency, but that is almost the opposite of FUEL efficiency.

There is a slight exception... underpowered cars will see a gain in mpg in certain environments ie hilly streets because you power up to cruising speed faster. Cruising requires about 12hp while acceleration requires up to 100% available hp.
