Lid?

i was looking into buying a lid for my 98 Trans Am, I do not have Ram Air and was looking to get that in the future, but i was wondering if i were to go get the lid , will i beable to keep it on when i get the ram air..
and also what r the best lids to go for, what fits the best and add the most power.
Thanks

I think all the lids fit either of the airboxs.

There is a lower WS.6 airbox which enables the hood scoops to work.
Then the stock one.

Pretty sure any aftermarket lids will fit both.
