if i buy a mass air flow sensor do i still buy a cold air intake even though the MAF is all of the same piping except for the filter or do i just buy a regular filter?

to see what i am talking about...http://www.sacramento-mustang.com/cgi-bin/cart.pl (its at the very bottom)

 

if you're not forced induction, the stock MAF flows more than adequate for bolt ons.

 

so dont even bother buying a MAF just get a cold air intake?
