  • FAQ about this diffuser
  • The #1 Best Selling Diffuser on the market for the Elise & Exige


Diffuser body is 2 inches (5cm) longer than OEM diffuser. Fins sit 5 inches (12.5cm) off the ground on stock suspension. Fins run parallel to the ground and extend forward to the undertray to channel air properly out the rear of the car. This reduces drag and improves downforce. Rounded fins match the curves and lines of the Lotus and also provide slightly better clearance than other diffusers.
