Why do you think that a poor company like K&N knows more than all the OEM's and their race teams?
Fact, K&N passes more grit into any engine.
Fact, diesels need better filtering than gassers.
Fact, The life of any engine running on the road with a K&N filter will be shorter.
Fact, the only time a OEM race team will use K&N is when the total engine life is measured in minutes.
Example = 720 minutes.
If you choose to pit your valves and pistons; it is your choice and right.
Please remember that new members will be seeing your posts, and might think it a good idea, when it is not on a diesel.
There is NO relation between gas and diesel engines, the engineering, duty cycle and service needs are different.
Using something from a gasser on a diesel is a great way to end up with scrap metal.
Ask a few members what overhaul total cost is for a diesel, if that does not scare you into caution.
