'09 Coupe 2.5L swap
Yes the 70mm DBW throttle body still requires an adapter for the bolt pattern. The TB outlet diameter is bigger than the 2.5 manifold inlet, so the adapter is internally fluted to match them up. There are pictures of it above.But still takes a adapter ?
Since it’s a DBW engine in a DBW car, there is no IAC as idle is managed electronically via the TB. So the adapter does not need a provision for the IAC valve as there is not one on my car.
