Over the summer, I installed a K&N Lifetime filter into my GT's factory airbox. I have had no problems with it until the temperature began to drop this month. When ever starting my car on a day that is 55 degrees or less, there is a very loud howl coming from under the hood. This eventually goes away as the car warms up but it is bothering me. Has anyone heard a similar problem and know a solution? Thanks!
