The lower intakes are the same. The GT40 also shares the same lower. I belive a few years explorer had an external EGR so no EGR passage. The uppers flow much the same. They are pretty much identical.
Basically looks, except that the '93 cobra intake had a built in EGR spacer while the Explorer setup uses an EGR spacer I believe. And for the SN owners out there, an SN95 adapter elbow will work plug and play with the explorer intake while it needs some fabrication on a 93 unless you do a Fox TB swap.
