can anyone tell me the difference between a 93 cobra intake manifold and a 94-95 cobra intake?  Why is 94-95 better and how do I tell them apart?  

I've never heard the '94-'95 Cobra intake being better. However, a surefire way to tell them apart is the '93 Cobra intake doesn't have the curved inlet like the '94-'95 Cobra intake.  

I'm looking to put one on my 5.0 TBird and was told the 93 wouldn't improve performance but a 94-95 would.  thanx for the info  

Correct me if I'm wrong, but doesn't your T-Bird have the same intake design of the '94-'95 Mustang V8s?  

I believe so, that is why I am asking about swapping the Intake with a Cobra Intake.  Wondering if the cobra Intake would increase low end torque as I seem to be week in that area(great mid range though).  

I've never owned a 5.0 T-bird, so I can't be 100% sure.  What I do know is that the 94-95 Cobra intake is similar in performance to the 93 Cobra intake.  Because the 94-95 intake has the same (or similar) shape at the throttle-body side, it would probably be the easiest to swap with the fewest modifications required.  

thanx-
