How could this be?????Drew said:
It is because the MB engineers did do a long term study and tests using the K&N filters and what they found was that the filter did let in more air. HOWEVER, at an expense of larger dirt particles. As a result, this is deterimental to the long term life of the vehicle, and also the reason why the MB engineers do not recommend it.
I just cannot imagine that Mopar would sell this if it were true.
(Could it be that most other cars don't last long enough to be affected by this failure mode. Could it be that "long term ownership" in America is up to the end of the lease?)
Love to get a reference for the study. Not that that will change anyody's mind....
PS Dale- "not promoting a product is not the same as disapproving it's use." I guess I'd agree. Unless the reason they are not promoting it is because it does damage according to their tests.
All hypothetical until we see if there really was a test with data.
