6.7L Cummins Forum

Just wondered how to go about changing the air filter element? Does anyone have any pictures? Thanks

Sorry Bud, I've been working 10 hours a day 7 days a week for a while. I have the Volant installed so I'llfind the OEM intake and take some pics of it.

Testing Air Cleaner Element using Filter Minder™




Do not attempt to unnecessarily remove top of air cleaner housing for air cleaner element inspection on diesel engines.
The air cleaner (filter) housing (5) is equipped with an air Filter Minder™ gauge (3). This air flow restriction gauge will determine when air cleaner element is restricted and should be replaced.



The Filter Minder™ (5) consists of a diaphragm and calibrated spring sealed inside of a plastic housing . A yellow colored disc (2) attached to diaphragm moves along a graduated scale on side of Filter Minder. After the engine has been shut off, a ratcheting device located within Filter Minder will hold yellow disc at highest restriction that air cleaner element has experienced. A drop in air pressure due to an air cleaner element restriction moves diaphragm and yellow disc will indicate size of air drop.
CAUTION: Certain engine degreasers or cleaners may discolor or damage plastic housing of Filter Minder. Cover and tape Filter Minder if any engine degreasers or cleaners are to be used.
To test, turn engine off. If yellow disc (2) has reached red colored zone (3) on graduated scale, air cleaner element should be replaced. Refer to Removal / Installation.
Resetting Filter Minder: After air cleaner (filter) element has been replaced, press rubber button on top of Filter Minder . This will allow yellow colored disc to reset. After button has been pressed, yellow disc should spring back to UP position.
If Filter Minder gauge has reached red colored zone, and after an examination of air cleaner (filter) element, element appears to be clean, high reading may be due to a temporary condition such as snow build-up at air intake. Temporary high restrictions may also occur if air cleaner (filter) element has gotten wet such as during a heavy rain or snow. If this occurs, allow element to dry out during normal engine operation. Reset rubber button on top of Filter Minder and retest after element has dried.


Filter Removal


1. The housing cover is equipped with spring clips and is hinged with plastic tabs. Unlatch clips from top of air cleaner housing and tilt housing cover up for cover removal.
2. Remove air cleaner element from air cleaner housing (5).

Thanks for the information and diagrams. I do appreciate it.

This is helpful, however I think you should change the filter at least once every two years if you live in a dusty area like I do (Las Cruces, New Mexico). You might consider a permanent filter which can be cleaned. I've read they improve air flow which would help improve MPG.

if they flow more air, they also flow more dirt.

That is not true. You can flow more and achieve equal or better filtering than OEM. OEM filters just need to meet bare minimum specifications. It not in the car manufacturer's interest to produce a specification and product for highest possible air flow and highest filtration. It would bloody expensive and tap into their service market profit of replacement parts.

I have used K&N oil filters for well over 1 million miles total to date. Best performing filter (when properly handled) around. Would not go without it. I keep two, one in service, other washed/oiled ready to go for a fast change.

The are others out now that make excellent high flow high filtration filters that are either oiled (reusable) or dry (disposables). Some of which have well proven usage in the dessert's of the middle east servicing troops in very nasty conditions.
