I just bought 2002 Trans Am WS6 6 Speed and it come factory with the pontiac functional ram air, my question is, is it worth my while to go out and buy say an SLP ram air intake kit, or somethin like an slp intake lid, will it give me gains at all?, aren't they the same thing or no?

 

a lid is worth while....the stock air box sucks.

but for your setup, there won't be much to gain from a ram air over the factory setup.
