The Speed-Buster is a simple bolt-on tuning module that interfaces with the stock vehicle electronics to "trick" the computer into making more boost. By sending modified signals back to the engine computer, the Speed-Buster tricks the computer into safely raising the boost. And with careful programming of operational tables, the Power Module doesn't trigger torque limiters, monitors, or limp mode, which means safe power that won't kill your engine - or warranty!
The Injen intake for the F8X M3/M4 includes oversized filters, heat shields, and inlet pipes finished in high quality wrinkle black. The filters are sealed against hot air with the included heat shield but is not restricted like the factory air box. Not only is there more air flow but the intake induction noise is better as well! Open up the intake and turn up the speakers!
