Charles R from WILKINSON, WV said, "The filter comes from the factory pre oiled and ready to install. It took me about 5 minuets from start to finish. This is a perfect replacement for your air robbing factory filter. I use K&N filters in my autos, trucks, motorcycles and ATV's because i like maxamum air flow and it gives exactly that. AutoAnything had the best price and shipping of any online seller."
