Hi,

the air filter on the Koleos is due for replacement (power cut in "high" revs (3000+)). Since we will not sell this car and I like custom things, I'm wondering if it could be an issue if I ditch the factory airbox and inlet tract to put some aftermarket washable filter in place. See the picture :



I recognize it's a fantasy but could it have negative effects that I'm not aware of ? boost threshold is as low as 1700rpm.

I'm leaning towards silicon or metal inlet tract, and a dual-stage foam filter.

If there's black smoke look for a boost leak, if there's no smoke check fuel pump&filter.

Don't, just don't, especially on this engine. Well, it could work perfectly, but you won't gain much if anything smile

I understand that there will be no performance benefit wink personal aesthetics.

The filter is just clogged. If I remove the filter, there's no cut. I do this test everytime to know if the filter is due for replacement (20000 km).

Here they have a reputation for going through air sensor and turbo quickly, but my guess is poor maintenance (I think OEM recommendation have very long OCI). Some cracked head reports too, from time to time, but mostly on early engines.

(this is to be taken with a grain of salt, on forums or car magazines most of the time you only see the worst, and not the perfectly happy users with perfectly running engine haha)

The majority of aftermarket filters are less efficient than factory paper filters so cause more damage to turbo, bores, rings etc.
If your filter is clogging too quickly then the best solution would be to use an air filter & housing with more surface area to allow greater life.

If you insist on an aftermarket intake look at ITG who make various different combinations of airflow/filtration in all of their products. http://itgairfilters.com/page/foam-specifications/

Just swap out the factory filter more often.
