Ok have a 2004 Mach 1. Installed a K&N years ago.
About a month ago I cleaned and recharged it but every since then in the early morning hours when its 65* or less outside I get an odd sort of grinding sound coming from the air box. It only makes this noise on cool morning and anything under 1000 RPM's. 1k and up no noise at all.
So any ideas why after a clean and recharge Im getting this sound?
