I have the opportunity to buy n aFe cold air intake for my 08 5.4 for 75.00. My truck has exhaust already and may get a programmer when my truck is out of warranty. My question is should I just stay OEM or go for it with the aFe?
agreed. the stock air box and filter will flow more air than the engine will ever be able to use.
and it draws the outside air straight from the grill, so there is no added benefit to a cai kit other than making your wallet lighter. .
