did some searching and literaly every post was a CAI for either a hemi or a 4.7... none for a 5.9.

Im not in a position to buy one of the 300$ ones, so i was wondering if anyone has made there own or found a cheap one.

You can use this post as a guide. The only difference might be the diameter of your throttle body. Not really sure as I have a 4.7. Somebody will chime in if I'm wrong though.

 

You could try looking in the 2nd Gen Ram section, since the 5.9 was only in the 3rd Gens for one year...

 

try a round air cleaner.. i have a 10x3 sitting around... its cheap... i defiantly noticed an increase in acceleration. if interested lmk

 

A round filter is really the only way to go if you do not want to spend $200+ for a K&N or Volant. I tired to use one from a 2001 5.9L off of ebay and it didnt work out. I just put a K&N drop in filter in and it works fine. I know Shiloh has a cone filter on the end of his existing tube where the air box sits now and he said he can feel it suck pretty good.

 

the only way that I could see would be cutting the throttle body connector off your factory set up then attaching a tube with a filter on it. Or buy a volant!! I have one and love it!!!

 

you can can a round filter at advance auto,14x3 for like 40 bucks

 

I like the idea of a round filter, ill do that. thanks guys

 

there's one company that does make a full cai for the 5.9 but I still feel that any CAI on our 5.9's is useless, we don't have the hemi hat or anything like it. Just place a K&N drop-in in the box.

 

here is mine when i had the round filter.... youll have to fab up your own bolt though, and youll need a 10" round cleaner for the 3rd gen, i couldnt get a 12" to work dp to the placement of the a/c pump on the 3rd gens
holley makes a 10" kit


the bolt will need to be bent like this
