From memory they were around $80-$90 new from Ford.
Can i make a suggestion, i don't know if it will fit over the throttle cables or not, but get a Territory intake pipe, the BA/BF Falcon tube is a little 'squashed' underneath so it can clear the low bonnet as opposed to the Territory's higer bonnet. The intake tube is a little more 'round' where it goes over the rocker cover. BUT you may need some spacers where the tube bolts to the inlet manifold to lift it up a little. Otherwise, just stick with the Falcon intake tube, might be easier haha.
Hope that makes sense.
