I recently installed a S&B Cold Air intake on my 3.0L. Following the detail instructions, it only took me under 2 hours to install in my garage. It is a very professionally made kit and looks pretty sharp under the hood. The S&B intake did give the truck a throatier intake sound and that nice turbo whistle at the lower range. Overall I have noticed better performance in the MPG and reduction in the turbo lag. This past weekend, I did a long road trip (700 miles) and I was able to maintain a 29-30mpg highway while maintaining a 77 mph highway speed. The only thing I have not like about the S&B system and have not heard anyone else talk about this issue, but at idle, the truck has a whomp like sound that comes from the intake. My thinking is that could be the waste gate on the turbo dumping from the extra air intake. To me, this is so minor to the overall improvement and feel.
Thought I was going to open up the exhaust a little until I looked underneath and saw it was just a straight pipe all the way from engine!
