Keep you standard air box, just uprate the filter to a green panel one. As with the Cupra/FR the airbox connect to the front of the bumper.
The only
problem with the
ibiza is that the engine bay is packed... nothing will fit in there. Got a green cotton dynatwist and with a forgr TIP the heat sheild wont fit on.
It easier to do a CAI on the Leons more room in the engine bay, the ducting ends up nearly running back on itself in the
ibiza. Depends upon which Leon your looking at also, if it a 225 then no it not the same engine, uprated internals and a K04 turbo. Also no other engine within VW/Audi/Seat has BBU engine code.
I'd stay with the standard air box or go for a TDi airbox only
problem there is its a 3" MAF size so.... that means a new TIP (not the mk4 forge current one) and MAF. Than a Map to accomodate the increaded airflow.
What I'd do.... to get 240bhp is....
Uprated downpipe... Milltek or who ever -
Full exhaust system... Milltek or who ever
Induction kit - change OEM panel for green cotton one.
4 bar FPR - from a passat (order mine from
http://www.eurocarparts.com/)
Then either Revo Stage 2, Custon Code Stage 2, Jabba custom map, P Torque custom map.
No doubt Evo is running roughtly the same setup
