From what I've seen Airaid makes the best quality intakes for our cars. Their airboxes are really nice and keep out unwanted hot air from the engine and even connect up to the grille inlet that's on our cars. JLT would be my second choice.
Only one I go with is C&L. They build top quality products and def know their shit. Their tunes are amazing as well for being mail order and are always spot on. They also make some of the best intake manifolds too.
On the 3Vs like Frank has the JLT 110mm CAI and the C&L Racer are the 2 best CAIs. I wouldn't say that the C&L is the best on the 5.0s, while it is a decent design I wouldn't say it is the best.
For the stock intake manifold I prefer the Steeda or the Air raid Cold air intakes as they utilize the factory air intake scoop and not a lot of people have issues with them. If you have the Boss IM than the Steeda CAI made for the Boss or the Parnelli Jones CAI are my two picks.
See I loved my C&L on both. Never any issues and excellent gains. Airaid I avoid because of their close association to imports lol. I prefer full on american parts if possible for my cars unless its a foreign car.
