Rear Wind Diffuser — engineered airflow, smart price

3gCustomz has redefined the rear wind diffuser with a stronger, more affordable design engineered to manage airflow at the back of your vehicle. This wind diffuser smooths the transition from the high?pressure air as the car moves forward to the low?pressure wake behind it, helping reduce turbulence and clean up underbody airflow.

Why choose this wind diffuser

  • Proven aero function: Helps manage underbody airflow and reduce rear-end turbulence for a cleaner wake.
  • Rigid and serviceable: Modular, bolt?together design adds stability and makes finishing or future service easier.
  • Built to last: Supplied with stainless?steel hardware for corrosion resistance.
  • Flat, stress?free fit: Includes the correct spacers so the diffuser sits flat—no deforming sheet metal to “pull gaps closed.”
  • Finish it your way: Minimal prep needed for paint, powder coat, polish, or wrap to match your build.
  • Model?specific hardware: No random bag of bolts—hardware is matched to your application.

Material and construction

Manufactured from 1/8 in. (approx. 3.2 mm) brushed aluminum in a mill finish. The bolt?together, multi?panel construction delivers excellent rigidity while allowing flexible finishing options.

What’s included

  • Rear wind diffuser assembly (multi?panel)
  • Model?specific stainless?steel mounting hardware
  • Correct spacers for a flat, factory?grade install
  • PDF installation instructions (download available after purchase)

Finish options

With minimal prep, our rear wind diffusers are suitable for customer painting, powder coating, polishing, or vinyl wrap.

Installation notes

  • We strongly recommend a complete test?fit before prep and paint.
  • Basic hand tools required; professional installation recommended if you are unsure.
