Purpose-Built Headlight Intake for the E30

  • High-beam replacement intake: Replaces one 5.75" ellipsoid high beam with a functional intake duct.
  • 3" rear outlet: Easily adaptable to aftermarket intakes, turbo setups, or custom ducting.
  • Velocity-stack inspired design: Smooth internal transitions help guide airflow cleanly under the hood.
  • Perfect for modified cars: Ideal for cold-air intakes, engine swaps, or forced-induction builds.
  • PETG-CF material: Carbon-fiber-reinforced PETG resists heat, vibration, and wear.
  • No cutting required: Bolts directly into the factory headlight bucket using existing mounting points.

This intake duct is supplied unfinished and may show light manufacturing marks from the printing process. For best cosmetic results, sanding, priming, and painting are recommended. Please review listing photos for surface detail.
