For all of you that dont have the money for a real intake like me at the moment. Did you know on our integras the way they designed the air filter is that it has a plastic pipe coming right out of the filter into the inlet tube. This means you can remove the air box surrounding the filter and you will just have the filter connected to the tube. I did it and it sounds just like a short ram intake. I noticed a little improvement in throttle responce but couldnt reallly notice a differance after 2nd gear. Just some food for thought if you want your car to sound better without sounding rediculous by taking off your axle back.
HOLY SMOKEZORS!
Actually my man, you might want to not do that. Sure it sounds good, but that's about the extent of it. You're not really doing much to improve the performance of your car.
Basically that shitty paper filter inside the OEM air box is going to get extremely dirty, extremely quickly. Those paper filters arent the most amazing filtering devices. Microscopic particles can get through it very easily...and will do so now that you've opened it up to the dust/dirt/other foreign debris that collects in your engine bay.
The noise is just from the fact that the resonator is no longer a resonator. Sure it sounds "like" a short ram intake...but it isn't performing as well. The response you think you're feeling is basically your mind not being used to the new sound and assuming its "better."
And finally why in the world would you take off the axle back to make a car sound "better"?? Removing stock parts and not replacing them with upgraded performance parts is basically just assinine.
