UPDATE: i would actually say it works, before installation i got about 26-27MPG and now i got 29.1 MPG...in the winter...with no snow tires. i usually don't see over 28MPG in the winter and only in the summer do i get really good gas mileage.
the fact i got 29.1 when im not expecting to get over 28MPG is great.
now mind you i been sitting in traffic, short 5 mile hops and not exactly driving 200 miles in a row on a thruway.
biggest thing i notice is the engine braking is increased yet the car coasts like normal.
Gotta love the 2 door coup.
