Whenever I'm traveling over 30mph or so, and I turn the steering wheel to the left I hear a howl/whistle sound coming from the left side of the engine bay. I didn't hear it until I installed my K&N RU 3530 last weekend. Is it just air flowing up the wheel well since the tire is turned?
One more thing, when I push down on the front and rear corners of the car it makes a creaking noise on 3 out of the 4 corners. What is that?
