I have had the intake (Rousch) on for about 3 weeks. I have not put on the exhaust system (haven't had the time.)
There is a marked and very real difference in gas mileage. I am anal about gas mileage and do the calculations each stop at the station. I have gained ~3mpg. At 20K+ miles/year that I put on, that equates to a substantial savings. I suspect that this difference will remain in tact as my driving style is fairly consistent... but time will tell.
Once the exhaust is on, I will be able to see if there is any difference in mileage...
