OEM-Exhaust Rear Diffuser for Mazda MX-5 NC (2005–2015)

OEM-Exhaust Rear Diffuser for Mazda MX-5 NC2/NC3 (2009–2015)
Lightweight. Precision-fit. Race-inspired.

This rear diffuser mounts directly atop the factory rear plastic valence and is designed to work with the OEM exhaust system on all NC2 (2009–2012) and NC3 (2012–2015) Mazda MX-5 models. With a weight of only 1.4 kg in carbon fiber, it adds aggressive styling and improved rear airflow management without compromising the car’s balance or requiring exhaust modifications.=

For NC1 (2005–2008) applications: Fitment is possible with minor modifications to the valence or mounting points. A reference installation on an NC1 (white car) is provided for guidance, though this is considered a custom fit and not recommended for those seeking a fully OEM-compatible solution.
