Welcome to Flyin' Miata!

NA/NB plastic undertray

Undertray all pretty!
NA/NB plastic undertray
Stock replacement plastic undertray

Availability: In stock



The plastic "belly pan" or undertrack beneath your engine isn't just there for stylish good looks. It's also there to help air go where it's supposed to go. And over the years, they get pretty tired looking. There are some aftermarket options out there, but the factory one still does the best job of actually controlling airflow.

This is for all NA and NB models except the MSM. It can be made to fit the MSM with some modification.

Mazda part NA01-56-111F.

OEM, or close enough that you can't tell.
Fits just like stock. Looks good, no ragged edges or excessive flash. When you take into account the free shipping, this is pretty much the best deal going.

Note from FM: It's a legit Mazda part.

Everything fit perfect and was able to mount it within 30 minutes with trying to find the right fasteners.
Purchased the vehicle and it did not have an undertray. Miata receives a lot of positive pressure in the engine compartment without an undertray. Perfect OEM replacement.
