    Re: Air Intake Manifold upgrade - at what point is it really needed

    I discovered something with the SD enclosed filter. It was because it was sucking water through a seam. It shouldn't be doing that. That tells me there isn't enough inlet flow. Apparently an exposed filter with a good heat shield will accomplish the same thing. I also noticed most of the dirt would collect in one area. I removed the element from the housing and made a heat shield. My intake air temps didn't change one bit. As an engineer, I have an understanding of flows. It indicates the chamber is in a vacuum. Now the filter seems to collect the dirt all the way around. It's your call. Just my $.02.

    You need the down pipe because you need to install the sensors for the engine to run right. You'll get codes too. Going right on the front of the turbo is a bad option.

    My filters have dirt evenly distributed. The trouble is, everything after the filter does, too.

    I "liked" your post, but I also hate it.

    We've conducted dust removal efficiency tests on a number of popular aftermarket air filters. I can't post the results, but in general, most of them are pretty bad. Probably similar to the filter you had.

    I love how posts take turns and twists. No, I really do. It's like having a conversation with a group of friends. I starts somewhere and goes in a different direction. Sometimes it gets back to the beginning. Anyway, I have a S&B intake with a dry filter. Totally happy. I haven't noticed more dirt in the tube to the turbo, but I have noticed more dirt (and bugs) in the filter. 'Course that was last fall and I won't see green grass for a couple of months.

    Ahhhhh.... Green grass.... I almost forgot what that looks like until you mentioned it. Wait, I shouldn't digress THAT far. That's a good point -> Keep your eye on the duct downstream of the filter. A very, very slight amount of very, very fine white talcum looking powder, after many, many miles (like 50k miles on the filter) is probably okay, but any amount that turns a white glove even a little brown, is bad, bad, bad. I'll see if I can find some pics of what looks "okay" and post them. @Rhinopkc already posted an example of what's REALLY bad. Way beyond what's permissible. That's enough dust to take a measurable amount of life out of a 6.7 If a heavy duty truck or bus customer showed us that pic and proved the filter was the cause, and had some engine issue like excessive oil consumption or increased blow-by flow rate, we'd very likely be paying for an engine rebuild.

    I think I've got a cousin that lives in Ft Atkinson. It's hard for some to understand, but I spend more $ on gas for my snowblower that I do for my lawnmower. I'm convince I don't mow grass, I mow green stuff that's mostly weeds. I tell people; 'We have two seasons, bugs and snow' As far as the filter is concerned, if I think if the dry isn't doing it's job, I'll try a wet one. They make both. I'm an old gas guy with not much experience with diesels, but I think the concept is the same. 'Cept for turbos. We didn't have turbos. "Turbos? We don't need no stinkin' turbos." Yeah, well, that's all changed.

    Excellent point

    I remember seeing some results like that a year or 2 ago. Made me think I may put my factory filter back in. The only reason I haven't is because I do an annual house cleaning of the intake system. I never find anything collected in the chambers or on the turbine blades. My intake sensors are always clean too. Even the wipe test on the compressor blades comes clean. It's been actually better since I removed the filter enclosure. While my truck works and pleasure, it certainly doesn't see something like a farm or oil fields may produce for an environment. I'm fairly happy with what I have and there is no reason given for me to change it right now. So I leave it.

    I have seen some nasty compressor blades behind a K & N. Spooky
