Review on Banks 42142 Ram Intake System by Jay Koterba

Some people will tell you that this system is no better than any other cold air intake system. I think it's really important. I installed mine on a 2007 Duramax LBZ and I have to tell you the motor ran with a lot less effort than it did half an hour ago. It climbs a 1 1/2 mile hill that I climb everyday with less engine workload. On the freeway on the ramps the engine revs faster and revs seem smoother and once I got up to my cruising speed it just stabilized and revs dropped and it just seemed to run and purr effortlessly. I have installed this system on several of my previous trucks and have noticed a difference in each one. I wish they were a little cheaper, yes, but I remember gas at 0.33 cents a gallon when I was a kid. So yes I would recommend this product to anyone with diesel fuel. I recently towed my stock 4 Angus head trailer with this kit installed with no other mods installed and it pulls better. It's hard to describe "pull better" if you don't know your truck, but I know mine and I'm satisfied. I don't spend money on things that don't work. I'm glad I spent the money on another excellent Banks system.
