To help channel the high-speed airflow coming from underneath the car, diffusers redirect the high-speed air flow to transition smoothly into the low pressure vacuum at the rear. This encourages a smootdher air flow underneath the car and allows better performance from other dynamic components such as aerodynamic wings.

APR Performance now makes a custom diffuser for the 2023 and up FL5 Honda Civic Type R. APR diffusers are vacuum-bagged and cured in the autoclave at high temperatures, ensuring quality, durability, and extremely high strength-to-weight ratios. $1,700 at time of publication.

  1. You’re kidding right? what’s the kickback from APR on this article? That ain’t no diffuser.

  2. Unless the CFD is provided with such a questionable product, I am disappointed this was included in the NASA news letter.
