hey jon,
i did have a pod filter on but then i put the airbox back in, as i was tolf 1 intake mod at a time so i ditiched the pod to keep the cooler!
and yeh i do had an aftermarket i was installed as a return flow but 'its not a return flow' so there are heaps of bends, and joiners all the way to the intake pipe that crosses the coil pack valley.
im after a close pic of where the factory pipes meet up with the factory cooler ( or a return flow fmic)!
i hope this helps a lil more
cheers anyway
