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.
Features:
6061 Billet Aluminum
Option of Red or Black Anodized
Breeze Hose Clamp and Rubber Cap Included for a Complete Installation
100% Engineered, Tested, and Manufactured in the USA
Just installed and fits perfectly! Looks nice and sleek in the engine bay. Love the titanium touch. Just ended up buying the full titanium dress up kit and exhaust manifold studs too! Great product!
