Cheap C.A.I. vs Expensive C.A.I. ???
 
Ive got what I hope is a simple question.

Whats the difference between the cheapo ebay C.A.I. such as this one

http://www.ebay.com/itm/02-08-Ram-15...item4aab8d70bf

and the expensive ones like this one

http://www.ebay.com/itm/K-N-57-1533-...item4159d3f882

Other than $200???

Thanks,

One thing I see missing from the cheaper one is the heat shield; the whole concept between a cold air intake is to pull cool air in from outside the engine compartment. The cheaper one looks like it will pull hot air from the engine compartment.

The "heat shield" seems to me just a big box of plastic. Seems to me like that would be easy to replicate.

I doubt plastic would hold up... I have a CAI on my truck and on my Wrangler and they're both metal. Not too say you couldn't fashion one out of metal either, but I don't think plastic would be a good idea...

well to be truthful prob. about .5-1hp if that you could make a homemade one and it will do the job is all about getting air into the motor and the tb can only suck so much in so it doesnt matter really which you get there is not going to be any real performacnce gains other from one to the other, other then maybe how much the air filter itself flows.

I don't argue that performance gains are minimal, but you need to do some research if you believe that hot air and cold air into the engine produce the same outcome...

yeah i have and if you look at the one in the pic he put up it draws its air from down low behind the the pass. side head light so it would get just as much hot air as the other as with the other he has on there it will get hot air also because the top is not sealed and does not touch the hood so hot air would blow right over the top of it also there may be at most a 5 dregee temp difference between the two if that

Thanks for all the info guys, I am just trying to figure out if there was any major difference. I have seen the threads where guys are making their own CAI, thats what made me look for cheaper ones than the $200+ ones out there.

couldn't tell you the difference but i will say that i just installed the 47 dollar one about a week ago and it seems to be fine

Two things I would be concerned about when buying the cheaper stuff...
1. Installation or Fitment - I some cases companies that offer very inexpensive items tend not to worry about if it actually fits and installs well. They try to produce items for a wide array of vehicles. The higher end manufacturers seem to do more R&D into the item.
2. The quality of the filter - I've heard of some cases where the cheaper filters have come apart after a period of time. Not good for the intake at all!!

I'd recommend getting the kit and replace the filter with a K&N or the like and maybe see if you can construct a heat sheild box. You'd probably still be under the cost of a high end kit.
