WHY TO BUY?
If you are serious about vehicle performance then you already know that aerodynamics play an important role in your vehicle's ability to go fast. Controlling airflow through the use of BMW M4 diffusers is a great way to improve aerodynamics and keep your ride glued to the pavement. Aftermarket BMW M4 diffusers will also give your ride a great aggressive look which makes them the perfect addition to show cars as well as track machines. Here at Andy's Auto Sport we have a large selection of BMW M4 diffusers for you to choose from. Whether you want subtle or wild, you are sure to find the perfect diffuser to suit your taste in our expansive collection.

DID YOU KNOW?
Diffusers were born in the world of racing by the never ending quest to go faster. Aerodynamicists determined that by channeling air into the right places you could reduce turbulence and effectively reduce drag. Shifting pressures underneath the vehicle also allowed for improvements in down force to maximize road adhesion. Aftermarket BMW M4 diffusers are simply air guides that have been carefully designed improve your vehicle's aerodynamics. Both effective and stylish they are a great way to boost your ride to the next level of performance while giving it a cutting edge look.
FAQs
Q: What is a diffuser? Why buy one?
A: A diffuser is an aerodynamic device which helps improve down force and reduce drag thus improving both speed and handling especially on the race track. Diffusers normally mount underneath your vehicle at the tail end of the car and help the high speed air under the car transition into slower flowing air at the rear of the vehicle. By making this transition smoother the vehicle becomes more slippery through the air, and by speeding up the air in front of the diffuser, the vehicle gets pulled harder toward the ground. These same principles apply to other areas on the car, so you will also see diffusers mounted on the roof or near wings on vehicles. In addition to becoming slipperier and stickier, diffusers also give your vehicle a tough aesthetic that just screams “race car”. If you are serious about going fast and minimizing lap times a diffuser is one of the most effective aero devices out there.
