This radiator and fan kit is definitely a big improvement over the stock setup.  You will see in the photos above the difference between the stock radiator and fan on the left and our radiator and fan kit on the right.  Our radiator is 1- 1/4 " thicker than the stock radiator and is triple passed to provide maximum cooling efficiency. Our fan kit includes a powerful SPAL fan mounted on a full shroud.  The full shroud causes air to be pulled through the entire radiator and not just through an area in the center of the radiator where the fan is.
