Mishimoto Sound Generator Delete Kit 2015-2022 STI/2013-2021 BRZ/FR-S/86

This simple kit allows you to plug the “sound generator” hole in the intake of your 2015-2022 Subaru WRX STI or 2013-2021 BRZ/FR-S/Toyota 86. Just remove the stock sound transmission tube, and plug the hole in the intake with the custom-CNC-milled aluminum plug.

The kit also includes a rubber domed plug, but to be honest we have not figured out what that part is intended to fit.

Fits all 2015-2022 Subaru WRX STI, and 2013+ BRZ/FR-S/Toyota 86.
