This is an inlet hose with a cap for the sound generator tube. The engine compartment has been cleaned and a subtle increase in performance has been achieved in combination with a high capacity air filter. I had to replace the air sensor clip because the filter was too big. I hate clamps that have to be held with pliers (I forgot their technical name) so I don't even consider it a loss. Tip: When installing, you can actually completely unscrew the sound generator box and pull it out to the right of the car. There are only two small pieces of plastic holding the tube in place and it pops right out. There will be a small hole where the hose went under the glove box. I just put a piece of tape on it because it's completely invisible and not visible. The sound in the cabin has dropped significantly; Now you only hear the noises that the motor actually makes.
