   Hi guys.
   
   Got one of these, and I need to know a few things
   
   - I've got the 90o hose, what do I use to create a cold air feed?
   
   - Also i've heard a lot about breathing mods? could someone tell me what this is and why it's needed?
   
   Thanks

   just need some pipe that goes from the filter to the front grill so when your driving along cold air is pushed in to the pipe therefore feeding the air filter with cold air and not warm air from around the engine. breather mods just get a engine breather filter job done

   ahh okay, can the pipe just sit in the grill? like the current one?
   
   also can I do the breathing mods or is it more complicated?

   If you have got the kit brand new you should have some black metal piping. just cut to the size you need. make sure the end of the hose is somewhere where it can access fresh cold air.

   I just connected mine to the black air scoop that was left from the standard airbox, you can see it in the first pic right on the slam pannel

   90o bend is part number A90-70
   
   70mm to 57mm reducer is part number S70-57
   
   the reducer will only be of use to you if youve got a furio throttle body or maybe a vtr? better if you check the size yourself
