Ok, I'm bored this morning. Do any of you have any experience with AFE cold air intake filters? I have one on my Chevy 2005, 2500 HD. I also matched the exhaust. I'm contemplating adding the AFE torque tube. The dealer tells me that there is no difference between the aftermarket and the factory intake tube. I'm also going to add a superchip in the near future. I'm looking for a little more horsies and gaining some fuel efficiency. Any other mods you'd recommend?
