Installing Pedro's Hi-Flo Air Intake 986 2.5L

[Pianohawk]

My wife and I bought all the supplies for this mod. We were really excited to install it and then we opened up the engine compartment and discovered two tubes attached to the OEM air intake (see pictures). What do we do with these? lol Perhaps they're addressed in the DIY (http://www.pedrosgarage.com/Site_3/Make_a_Hi-Flo_Intake.html) but we didn't see any mention of how to connect them to the new tube or if we simply discard them?

I'd like to finish the air intake today if possible. Does anyone have a minute to offer further instruction on finishing this?

thanks!!
