Big difference noticed immediately.
Ordered this and received the intake in 5 days. It was shipped quicker than I expected. The thing wasn't hard to install and I am not a mechanic. It only took about an hour for me to install. Performance wise, you are able to hear that roar when you you're accelerating and notice a big difference in Horse power. I would recommend for anyone to get this upgrade fast. I just installed the package so I can't say I've seen any improvement in mpg yet.
S&B Cold Air Intake
I am a hot shot driver and drive all over the United States. One of the mechanics for the company I lease to recommended getting this Intake System. I installed it in about 2.5 hours. I am very impressed with performance as I have seen an increase in mileage. 1 to 2 miles per gallon city. 3 to 4 on flat/level highway. My vehicle is currently throwing a code concerning the air intake. I contacted S&B and they have told me that they are working on a correction.
