Lurcher, there are people who like to have horsepower yet still want good mileage so that they don't have to fill the tank as often. It's not all about the cost of the gas.

I heard from someone out of the blue at a party and asked if I tuned up my z4 because it can help add the horsepower and add more mileage, he told me that kit's name but I totally forgot what that was cause I was half drunk at the party.

I am just curious if there is such kit, but not sure if I will upgrade yet.
