6.7 engine air filter

[nlambert182]

I ran a S&B intake and filter on my 2012, and a K&N drop in on my 2016, and a stock filter on my 2018. There is absolutely zero gain from switching filters other than a lighter wallet. The stock intake and air filter does the job just fine.

I had thought about going with an S&B on my truck just to hear more of the turbo, but after hearing about some of the potential issues people have had, I decided against it. Sticking with the stock setup. At least for now...

If you want to hear more turbo, remove the baffle inside of the intake tube. I always do it to minimize the risk of the foam around it breaking off and making its way into the turbo. You can definitely hear the turbo after that.

I may give that a try. My wife hears it when she is sitting in the passenger seat even with the windows rolled up. I have military-grade tinnitus, so I can only hear it with the windows down.

Just returned from a two month / 12,000 + mile road trip w/camper using an OEM air filter. No problems. Am considering experimenting with a KandN reusable filter. Any input from anyone. Yes, I read the replies. Looking for more info.

I am using the Banks air filter & like it. I did notice an increase in power but I can't tell if the filter had that much to do with it as I bought their whole system & installed it all at once. Boost tubes, air intake horn, & filter. Their air filter system is huge! Takes up every bit of real estate in that corner of the engine bay. Gained about 1 mpg but again I am not sure if the air filter did that or the whole system combined. For the money it's not that much of an increase in any category, but I also purchased it to not have to worry about the grid heater bolt falling off into the engine.

A service guy at the dealer told me that Wix makes the filters for Mopar.

Who makes them changes every time they put out a bid for new contract for filters

That depends... maybe on the gassers but not on the diesels. Cummins (Fleetguard) makes the oil filters for the 6.7 Cummins and rebrands them as Mopar.
Racor/Parker used to make the rear fuel filter/water separator and rebrand it as Mopar, but at some point FG started producing that one as well. FG has always made the front fuel filter.

Wix does not, nor have they ever, made fuel or oil filters (rebranded as Mopar) for the Cummins.

Fleetguard makes the rear fuel filter branded as Mopar for the 2019+ trucks, Fleetguard also makes the front fuel filter and the one that is branded as Mopar... I have been told no one else meets Cummins requirement for 3 micron nanonet filter media, that is why as long as you have a warranty on 2019+ engines you need to use Fleetguard/Mopar fuel filters...

CHANGING TOPIC, since I can't figure out how to start a new one. Driving a 2021, 6.7 turbo. 72,000 miles now with only the air filter problem mentioned above.
After 47 years in the Merchant Marine I am habituated to preventive maintenance programs. I don't see anything about "pop testing" injectors. Anyone know how often injectors need testing? Also seldom see posts on when checking valve play is suggested. Thanks.

Engines in regular cars and trucks don't see duty cycles like marine or industrial engines do. Their continued operation isn't quite so critical either. People generally wait till something breaks versus disassembling things at a certain miles or hours and looking for problems.

It's often cost prohibitive to an individual owner to perform such tests as well and often times cheaper to just wait for a failure and replace the component when the vehicle isn't critical (such as a vessel breaking down in the middle of the ocean, or a truck breaking down with an urgent load on it).

I believe that valve lash adjustment is discussed in the owner's manual. When I worked in a diesel shop we didn't typically check valve lash on a vehicle unless A) it's a commercial truck in for a scheduled service or B) when the truck wasn't running properly. If memory serves, I "think" Cummins recommends checking it at ~150k miles and then every 50k miles after that, but it's been a long time since I've looked into it.

My 2022 owners manual I have yet to see valve check time or miles listed like I did for my old 06 5.9, if I recall was it 5 years or 100K and do recall some back then thought that was to long to wait so its up to you when you want to check the valves, as for injectors I have never seen any pop testing recommendations for the 5.9l or 6.7l Cummins engines, theses engines are not like what you have in ships out at sea..

2019+ have hydraulic lifters. No valve adjustments required

 

[nysharkbait]

Nothing insightful to add. Just want to say I appreciate y'alls knowledge and willingness to share it. On my forth diesel now, 6th Ram, and still learn as much from these boards as I did when I had my first truck.

Since 2019 model year Cummins made changes including hydraulic lifters so there is no 100k mile valve lash adjustment.
Pop-off pressure checking is for mechanical injection system for example the original 5.9 Cummins. The 6.7 is a common rail electronic actuated injector. The only thing to check on those injectors are solenoud operation, spray pattern, & spray volume per set duration (flow volume).
It's common to run 2-300k miles on stock injectors as long as fuel system filters are maintained and you avoid fuel contamination. There are vendors that provide the service of checking your injectors and rebuilding them, or you could just swap them out. Of course like anything else can fail which is why it is important not to ignore or continue running if you observe issues or MIL is illuminating.

That's more or less what I was thinking. Just seeing what members have to say about it.

Well, yes, completely different "duty cycles" but a diesel is a diesel it seems and things wear. Thanks.

I'll look around and find a diesel shop Thanks!
