when i ordered my sri from aem everything was there for me....and the thing you circle is simple... on your oem intake there should already be a tube connecting to it.. when you take it out and put the new sri in the tube should just fit right into place considering you have the same year car i have..... it is easy as pie....

 

ya, for some odd reason i didnt get 2 couplers that secured the rubber tube to the intake and the housing.
so i gotta go to like napa or schucks and get those.
but heres a pic of what it looks like nontheless.
pretty awesome, and definetly sounds better...

 

very nice congrats!!!! for a i4 you better get every hp you can get lol

 

thats for sure.
it definetly feels like it has more of a pull when accelerating just in general since it
never had an intake on it
so im definetly happy with it.
first few mods done, now to get down to the niddy griddy...
