Application & compatibility.
Mazda Miata NC · manual · 2006–2015
NC Miata with a manual transmission, including the PRHT. Automatic gear selectors are excluded.
Manufacturer application source ↗Applications shown here are limited to the configurations we documented. Use the manufacturer’s vehicle selector and confirm your engine, transmission, trim and part number before ordering.
What it does.
The knob uses a Delrin body and metal insert. Flyin’ Miata lists it for manual Miatas including the NC. The product changes the knob, not the shifter mechanism.
What to consider.
Shape, height and weight are personal preferences. This is not a short-shift kit and does not address worn shift components. The listed scope here is the NC manual, not the automatic selector.
Plan the installation.
Follow the seller’s fitment guidance, check attachment and shift-boot clearance, and confirm a secure installation before driving.
