Ej20 Intake

[Vecz]

So looking through the repco catalouge and it had an DIY intake section which looked fairly good and for roughly 100bucks, i looked under the bonnet today to see what i need to do, and i realised i have to do something with the three breaher pipes going into the current airbox. what can i do with those? how can i hook them up when i put in the new intake system? and it seems i can hook up this system onto the original air inlet, does this all sound alright?
