I recently installed the Injen cold air intake and was wondering what (if any) is the difference in sound that I should expect? At times (usually only in the mourning when I first start the car, I will hear a "hissing". Almost like I can hear the intake sucking in the air. This noise goes away in a minute or two. Is this normal. Do I need to tighten the clamp around the filter and the intak? The car drives fine and I notice a slight increase in performance, but I don't want to be inadvertently sucking dirt particles into the engine. Thanks.

hearing that sound is normal. you will also hear that sound when you shut off the car. the car will have a deeper sound when you drive it harder.
