Update on the air dam! HUGE difference! I can actually
see the numbers being higher more than my other mods! With my other mods I had to test them to get any idea of their benefit (other than noticing how they helped coasting), but this air dam is amazing! Whoever said that it is the single most helpful mod next to a boattail is right....I set my new short trip record today of 47.1 MPG (excluding the 47.89 MPG I got over a series of 4 longer, 30 mile trips). I tested it compared to my baseline yesterday (weather is literally the same), and got a 1.2 MPG improvement with the air dam, even with a slight breeze against me today with the air dam on. With my tank average of 40 mpg this results in a 3% improvement in fuel economy. Testing isn't perfect ABA, and honestly it feels like a whole lot higher; my Torque numbers have been crazy high since installing it.
It's a winner! It's definitely my favorite mod to date, not only due to it being relatively low profile compared to my other mods, but for it's hugely noticeable increase in FE. It's worth as much as my grille blocking and wheel covers combined on trips over 6 miles (grille blocking's effect is more noticeable percentage-wise over my shorter 5-6 mile trips).
DO IT! Get an air dam on your car. I swear I've never been so excited over a mod before.
