Looking to improve performance and gas mileage and this is the first step and a fairly economical one too.

The installation was a snap, good fit. I have noticed a bit of increase in mid-range power. I haven't had time yet to compare the gas mileage, but i'm only on my second tank of gas. So far I think it's better. Good investment.

It gave our 300S better throttle response, more power off the line & better MPGs. I installed it a day prior to driving from St. Louis to northern Arkansas. We got 25mpg on the way down (slightly better than the best MPGs we ever got) & 28mpg on the way back! Not the same exact routes but still impressive thru many hills. IMO on a flatter trip going 65mph I could get 30mpg. About 3x the OEM replacement but I'm sure it will last for the life of the car.
