A simple way to clean your bay.

Simplify your 2015-17 STI engine bay with The GrimmSpeed Sound Generator Plug Kit. The stock sound generator is an unnecessary system that contributes to a cluttered engine bay and can give an unwanted, artificial sound inside of the car. The problem with getting rid of this clunky setup is that you’re left with a hole in the intake tract. The GrimmSpeed Sound Generator Plug Kit is your solution. 

This piece is a high quality machined, anodized and laser-etched aluminum plug that is designed to perfectly contour and seal inside the stock post-MAF hose on a 15-17 STI. The outside flange is sized for flush fitment, making installation and removal incredibly easy. Once installed there is a subtle flash of anodized aluminum with the GrimmSpeed logo visible from all angles.

The plug is available with either a black or red anodized finish and laser-etched GS logo for a high-end, premium look in the engine bay and requires no modification to install. A new Breeze hose clamp is included to replace the stock spring clamp, along with a cap for the firewall side.
