 Subject: Home brew intake question
IP: Logged
Message:
Ok I'll try to keep this short. I made a home-made cold air intake for my truck yesterday. I made it from 3" PVC pipe and a K&N filter. I just went to Autozone and opened every K&N box till I found one that had a mounting flange on it that fit my pvc pipe. It turned out to be a cylindrical filter that cost about $56.00. I wasn't sure my creation would work so I made sure to get confirmation I could return the filter if I needed to. So I put my home-made CAI on my truck and went for a test drive. Maybe it was psychological but the truck did seem to run better and have better throttle response. And contrary to what I expected the engine seemed to run quieter, not louder. It seemed my creation had worked.
Now to make a long story a little longer, last night and today I read on here and other web sites how K&N filters may not filter very well and read the stories of fouled sensors, oil up in the intake, throttle body etc. I found a lot more bad reviews of K&N than good ones. It didn't make sense to me to have anything with oil in it upstream from my throttle body, either. So I removed the CAI and reinstalled the OEM unit with its Purolator paper filter. But I kept thinking about it and I found out that the K&N I bought from AZ is the replacement filter for a 2004-2006 Chevy Colorado. My truck is a 2001 V6 5-speed CC. My question is does anyone know if I used the plain paper version of the Chevy filter to make my CAI would it work as well? Or does the filter on a CAI have to be a high-flow like K&N or other oiled cotton high-flow type/brand? If I could get the Purolator, Wix etc. paper filters to work I would probably keep my home-made intake.
Sorry for the long post but I would appreciate any info.

K&N should be perfectly fine , IF you follow
their directions properly , re cleaning , etc.
Many have these filters and without the problems.
Anyone with problem is not following directions.
However , if you want to use the 'paper' variety
I would actually recommend you do a similar
"shopping" trip and find as big a one as you can fit in there , that way it may end up with something close to K&N performance..

WHERE IN THE WORLD do people come up with this
stuff
The only way that could happen would be over
oiling the filter during maitainance
And the dodge does not have a mass air flow sensor
in the system but an IAT incoming air temp sensor
in the intake and that sensor will work if its
coverd with oil unlike the flow sensor
The flow sensor is heated and when air flows
over the thin wires it has changes temp to tell
the comp whats going on now this with dirt or
oil will cause a problem
I used to clean them with brake clean now they
have a special cleaner for them
The flow sensors are also very sensitive and some
cold air systems will trow a code then you need
to use a diff sensor calibrated diferant glad
dodge don't use them
anyway take that IAT #2 intake runner out put a
1/8npt plug in the hole and relocate your
sensor 6" no farther from throttle body in the
air tube
this will advance the timing and add fuel a small
but noticeable gain as long as the o2 is working
properly
Also do the crank sensor mod and drop 1 heat range
on the plugs NGK Vpower FR5 run great

Thanks Larry. I did try a Fram paper filter with that home made CAI but it didn't work at all. Truck ran like a sick chicken and had a lot of ping with that contraption on it. I took it off and put the OE airbox back on. I am researching the mods here that will work and I appreciate your help.
