Smart Choice Cai
 
What would be the most cost effective way to add a cai to an 03 4.7 Ram. I really dont see the point of puttin down some plastic almost home depot style pipes for 200$ at the cheapest.. Is there a DIY guide to making one?

when i had an old suzuki jeep i had a muffler guy bend some pipe for me and we just stuck it to the throttle body and put a filter on the end. i'll see if i can find a pic. honestly it was pretty ghetto so i usualy dont point peepz down that ally unless you dont give a crap about how it looks or about Reliability

DIY. Very Easy. SUPER easy. Did mine in a couple hours. With painting and dry time.

Couldn't tell you HP or Torque changes without a dyno, but at the very least it is running much cooler on the guage and my MPG city improved about half a mile per gallon.

No real need to have a guide.

Use ABS piping, 3 inch. Will need a rubber 3" coupling for connecting to engine. I used 2x 3" long 90degree elbows. Then just measure out and connect the elbows with 3" pipe. Angled the end (going to the filter) downward just a little bit (not more then 10-15 degrees). Peiced it all together and test fitted it, then ABS cemented them together, painted it all with Krylon Fusion textures silver (feels like sand paper).

Bent a peice of metal that had holes run through it, bolted around the piping then bolted to the frame where the air filter box used to be bolted. Picked up a "Specter" filter from the local Schucks (Napa, Autozone, whatever).

On an 03 or newer dodge you will need to move the IAS sensor (has blue wires) into the CAI. Just drill a lil hole in the first elbow (by the engine) and mount it in there. You can then run the oil breather hose into the CAI or just pop a small filter on it (like I did).
