another part of intakes besides the cold air part is degree of bends, a strait tube will outflow a 90* bend. the stock intake has a lot more bends then most/all the CAI's on the market.

Sorry if this has been answered before, I wasn't successful in searching for this particular question.

The CAI is leagues better than drop in filter, but should combine CAI with performance exhaust. BAsically it can breathe in better and exhale better which create more HP & Torque. I would guess on a Ram 15 to 20 HP with both could be more based on engine size. It helps MPG too.

If "leagues" better is 6-8hp at 4000+ rpm then I guess you are right. Here is a dyno chart. I don't know what percent of your time you spend above 4k rpm but it's not much for me.

As others have stated, the 09-10's have a better(more of a true CAI) intake setup than the earlier Hemi's. A 2004 would see more of a gain than that dyno test shows as it was performed on a 2009.

No worries. Just wanted to make sure that was in the thread as many don't (including myself prior to joining the Z) know that the newer rams have that much of a better intake versus the earlier rams.

after market intakes increase volumetric efficiancy. there is a difference in cold air, and short ram. CAI normally produces more high end horse power but has a down fall since a true CAI routes to the bottom of the engine bay. it can pick up water if there isnt a precaution for it. short ram normally produces not as much but still good power. it draws in warmer engine bay air. an air ram and air dam are often used on this set up. im going to make a video showing the difference. ill send a link when i do.

Yeah, depending on the year of Ram or any vehicle for that matter will affect hp/tprque increase when using Cai and performance exhaust. One thing though I do not believe in spending 300 dollars for K & N intake with so many cheaper intakes out there (or build yourself) that perform as good or better.

One thing about Cai in regards to routing to the bottom and taking in water. I saw on EBay or somewhere a screen that prevent water (unless submerged) from being sucked in as easily. I can't remember seller, but I have seen them. Anyway, your information made me think of that.
