Like I said...

 

gains will be minimal overall. potential savings of a DIY is huge. You may be able to do a DIY, Sonnax, Jetscoop and still come a head than buying that K&N

 

ok so if i make one how will i accommodate the crank case vent hose into the pvc pipe? I saw someone list the things needed for their custom CAI and i didnt see anything that addressed that...

 

you can either drill a hole and put the tube in the PVC, put a $7 filter on it or install a catch can...

 

have you made one for a 4.7 liter? the crank case vent hose is long and on the left of the motor. THe hose goes on back a ways. Kinda hard to get to the other end. I dont see how i could but a filter on the hose and just leave it laying there. i guess my only option would be to drill a hole in the pipe and shove it in there and seal it up ????

I think i am going to make one. i just wanna know what to buy before i head to town...

 

I think I've done four in 4.7 Rams, plus one in a Dak and one in a Grand Cherokee, so that'd be a half dozen.

 

oh ok i see... i may just try to get a mini filter. I will rig it up some how. Im going to get some of my materials today. hopefully when i get this done i notice a little bit of gain in performance. wish me luck. i will try to post before, during, and after pics. Thanks hammer.

And i am like you as well .... im over here in bama and do alot of hunting on the family land. Cant do the TRUE CAI cuz i would def get in some mud and water.

 

The mini filter or catch can are the best options, routing that nasty ventilated crap from the oil into the intake is great for the environment, but lousy for the engine. It along with routing the EGR directly behind the throttle body plate are the reasons why the throttle body gets gummed up so bad and IAT sensors foul so often.

Any auto parts store carries the mini filters for about $7-8...

 

Just out of curiosity ... what size grommets do you use when installing the sensors.

 

I just bought an assortment pack when I did mine with like two of each size so I would have a spare just in case. Glad I did because I tore the first one trying to put it in the hole I drilled that was just a little too small. I don't remember the exact size but you could just measure the AIT sensor and that would get ya pretty close.
