air intake duct & airbox queries

Post by JLawson90 »

right so, decided to have an investigate into my air intake system & airbox etc and found some things im not sure about..

first up .. why does my intake duct right at the front have a big hole in? when ive found others that dont .. am I right in guessing the one WITHOUT the hole would provide better/colder air? and more induction noise? (i like noise)

secondly, I'm guessing this partially covered hole and plastic pipe is drainage just in case water gets in?

and finally, this mesh like plastic grate in there.. is this there for further noise reduction?
