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.
