Iam wanting to change out my cold air intake on my 2012 ram big horn 6.7 cummins . if I change it out is there any other adjustments that have to be done. Ive bought a Banks cold air intake for my truck

I don't think you need to do anything, it is kind of a waste of money as all you are going to get out of it is more noise - no real help for mileage or power.

I have a K&N on my 12. It came on it. I do like that it scoops the air from down low in front, under the bumper. However, the tubes that it is built with are larger diameter than stock. So, the air flows slower, so it sets off a MAF code. The only thing you can do to stop it is to put the factory stuff back on, or delete it (egr, epf, cat) and add a controller, or figure out how to reduce the tube size at the MAF sensor. I'm not sure if you will have the same results but I'd lean towards you will. I've been trying to find out the diameter of the factory tube at the point the MAF is at, also I'd like to see what the factory setup looks like. Maybe i can adjust the diameter at that point. Can you measure yours and snap some pics and send them? If your willing, I'll PM you me email. Also, what are you going to do with your factory setup? If I can find one I might just put it back factory.

I can do that Ill get this for you trmw.

That would be fantastic

Iam going to keep my factory intake just in case it doesn't work out. so this is the code that your getting p0102 maf volume air flow circuit,low input ?

yep

installed my cold air intake the other day put a couple of miles on it so for no codes .

Did you get any pics of the factory setup you can send my way. Also, when I clear my MAF code, it take a couple of days before it comes back, but hopefully you'll be ok.

didnt measure the in let tube I will get them when i get home tommorrow

mikey59

where the sensors are located not much room to measure. but I hope that this helps you

yes that does help. The measurement I'm looking for is the inside diameter of the tube that the MAF sensor is located in. I'm still considering asking oif there's anyone out there that just wants to meet up and swap intakes other than I like where mine scoops air from way down low.

mikey59

where that clamp is at buy the sensor it is 4 -7/16" ID

Thanks This is exactly what I've been looking for. And it's on here for safe keeping now.

This is my old thread about my MAF code from the underwold of darkness.

By golly I do believe I've got her solved. Crossing everything I have 2 of. I started with the fusebox, or TPM. Removed it, then carefully disassembled it, and cleaned what looked like mud washing out of it, as the contact cleaner spray did it's job. Then I went to any other connector I could find under the hood, then a new code sent me to the O2 sensors. When I opened those connectors, dirt poured out. A future project will be sealing them better somehow. Another project became opening up all of the wire loom, from the MAF back to the ECM. Not really possible without some major component removal. That turned into cleaning more connections to other sensors.

So far I'm running code free.
