Mishimoto Subaru Sound Generator Delete Kit 2015-2021 WRX / 2015-2021 STI

Tired of unnecessary engine noise in your Subaru’s cabin? Many modern vehicles route engine sounds—like intake roar or blow-off valve whoosh—through the firewall into the interior. While some manufacturers claim this enhances the driving experience, it’s not for everyone.

The Mishimoto Subaru Sound Generator Delete Kit provides a simple, effective solution to silence these unwanted noises. Featuring a CNC-machined aluminum plug, this kit blocks the sound generator line at the intake hose, reducing cabin noise without affecting engine performance. Installation is quick and easy, taking approximately 10 minutes, and requires no modifications.

• Eliminates unwanted engine noise in the cabin
• CNC-machined aluminum plug for durability and precision fit
• Direct-fit installation in approximately 10 minutes
• No modifications required—maintains stock performance
• Compatible with select Subaru models equipped with sound generator routing
