C6 Air Filter on C5
K&N makes a filter (part #RP-5135) with a carbon fiber top flange and bottom of Carbon Fiber. It is not as deep as the filter they make for a C5 application (part #RP 5070 no CF) but it is wider so it would seem that the air flow would not be mush different and it would be better than the stock air box.. Would there be any issues by using this filter over on that they supply for a C5? I did contact K&N as to what application this filter was for and they confirmed it was for a C6 6 liter and they did not recommend it for a C5 as it was not tested for the C5. I am thinking that was nothing more then a CYA statement.

The only thing that is different (I just found out), is the flange outlet on the filter is four inch and I would need to reduce it down to a three and a half inch to the MAF. Because of that I am not sure I want to go with that filter set up. It would seem to me that the reduction would cause the airflow to be disturbed and could affect the MAF, although I am no expert on that.
