SprintBooster Power Converter Review
I've always felt like acceleration was a little sluggish in my 335i, not the actual power rather the pedal feel, so I tried out one of our SprintBooster Power Converters. Definitely a difference you can feel.
Wrote an article about the experience if anyone was interested in adding this simple and easy modification to their e90 or e46. Install literally took less than 5 minutes. One of the simplest modifications you can add that will add a noticeable improvement to everyday driving.
