AFE Cold Air Intake

[JConquest]

I am looking for a solution to a repeating check engine light on the 2010, 6. 7 after installing an AFE Cold Air Box. The unit comes with a pre-filter sock and AFE has provided the 7 layer filter to try to remedy the problem, but I continue to get the check engine light every few hours. I am able to reset the code, P0101 "Mass Air Flow Sensor..... ", only to have it reappear a few hours later.

Just put the stock box back on it with the stock element. No more check engine light and better filtration.

sag2 gave excellent advice. leave everything stock from the turbo to the filter box. the only mod you can do that is an improvement is add a psm kit. the afe was junk before it left the factory.

Thanks for the response. I am not sure what a psm kit is and would appreciate any input. On my 02 Ram, I used the AFE replacement drop in filter and had excellent results. I was under the impression that more air flow would help the fuel economy.

Thanks Sag2. In reading the propaganda and talking with other owners, I was under the impression that the increased air flow would help with the fuel economy. That is the only reason I went to the after market filtration. What is your take on this concept and do you have any alternatives?

CKelly suggested a psm kit, but I need to find out what that is.

Here's their website: www.psmdiesel.com. You can do a Home Depot version for a fraction of that cost. I just went with their kit.

I'm not a fan of the serviceable air filters, mainly because most owners do not maintain them properly. Failure to keep them clean and properly oiled results in major engine damage from "dusting". On a 6. 7 any time you alter the intake flow you risk upsetting the MAF sensor as you are finding out. Since it's function is to control EGR you risk excessive soot generation. The stock air box flows very good, and it is pulling cool air from outside the underhood area. The paper element does a much better job of protecting your $15,000 engine so in my book why mess with a good thing.

sag2, what's your take on the seal around the edge of the stock box on the 4th gen? i haven't looked at my 2010 yet (just rolled 4000 miles), but I know my 01 had a terrible seal around the perimeter of the stock filter. I found dust trails on the clean side of the housing when the truck was bone stock. Some filter grease helped, but I was NOT impressed! The balance between flow, NVH and cost-of-manufacture seems to lean heavily towards the lower cost option.

I don't know how much the programmer developers (Mads, H&S, etc) are tweaking the MAF tables, but I know it can be VERY tedious and time consuming! My 09 Subaru WRX had to have a separate software load for each aftermarket air intake due to the different flow characteristics through and around the MAF sensor. Changing the intake tube's shape or size (and/or the filter, the sensor's location, almost anything) changes the actual mass of air entering the engine relative to the sample picked up by the sensor! Major PITA for the tuners...

I can't speak to the 4th gen trucks, but the only leaks I have seen on stock 3rd gen trucks are with aftermarket filters. For some reason the OEM filter seems to have a thicker seal that is less likely to pull free of the box. Most of the filters that do leak are well on their way to being plugged. Being plugged creates a great negative pressure that helps pull the filter in and collapse it from the center out.
