So I have been going back and forth on getting the OEM mud flaps. I'm glad to hear people haven't seen a MPG difference with or without them. I do kind of like the look of them making them look slightly more aggressive than without. My main concern right now is wondering if the mud flaps tend to help snow build up in the wheel well since its more enclosed. Has anyone has issues of snow building up in the wheel well because of the mud flaps?
