Jass Performance square gearbox filler plug for Mazda MX-5 NA NB
The Jass Performance square gearbox filler plug replaces the old corroded filler plug with a stainless steel plug. This part is no longer available from Mazda, so Jass Performance has made a replacement plug that is better than the original.

Features
Replaces square head filler plug

Note It is incredibly important not to overtighten the gearbox filler plug. We recommend using the correct factory torque specs when reinstalling.
