Air cleaner

On a TBI, will any 14x3 air cleaner work? will it fit under the stock hood? Because i am looking at this one that has a lowerd base and it is a 14x3.

It'll be fine as long as it's a lowered base and you don't remove the gold spacer ring.

another question now, if i get a TB spacer and have the lowered base, will it still fit?

Don't think so.
