BMW's 135i Coupe has been called a "car for the true enthusiast." That usually means the stock model is stellar as it is, but the right custom tuning can elevate a great car. This BMW 135i features dual intakes, a custom exhaust system with shaped downpiping, JB4 and Flash performance tuners which bring the car up to 400 horses, and for a smoother ride, they've added a KONI Ground Control suspension kit and set it on Michelin tires. One extra performance feature? It runs on E40 ethanol-enhanced gasoline for that clean-burning get-up-and-go.
