If you picked up a 3 series without the M Performance package simply because the dealership didn’t have that configuration in stock, you’re in luck! The M Performance package is highly sought after, because the upgrades make such a dramatic aesthetic impact! Our PhaseOne M Performance style upgrades serve the sole purpose of attaining that factory look without paying the factory price. Our F30 rear diffuser will fit any 2012 and on BMW 3 series that is equipped with the M Sport package, and if you don’t have the M Sport package you can look into upgrading with one of our PhaseOne aftermarket M Sport style body kits. If you have an LCI (facelifted) 330i or 340i, this will fit as well.
These F30 rear diffusers are constructed from high quality materials unlike cheaper alternatives you may find online. Durability is especially important for aerodynamic, because the last thing you would want is for something to snap or break during installation or maybe simply a strong gust of wind.
The performance style F30 rear diffuser also comes finished in matte black, and no additional painting / prepping is required. Just bolt it on and you’re good to go! This diffuser simply replaces the original flat design with an aggressively styled shark finned design for better aerodynamic functionality.
The key behind the high quality of PhaseOne parts is in the mold injection process. Our manufacturer has over 20+ years of experience automotive industry and we’ve figured out the perfect thickness in the molding process to produce extremely durable parts without sacrificing flexibility. This allows our parts to last the test of time, as well as fit perfectly snug on your vehicle.
Whether you have the stock OEM M Sport package from the dealership, of if you have one of our PhaseOne polypropylene body kits, fitment is guaranteed perfect!
Note: Please make sure you select the right exhaust option for your particular application (320i, 328i, 330i, 335i, 340i, or M3 style). If you choose the M3 style, you will need to modify your exhaust, or the pipes will not align properly.
