For over 60 years, Metra has maintained its cutting edge by paying attention to our marketplace and innovating products to fit the needs of the installer. Metra Turbokits are designed to be heard but not seen. This means that our fit and finish is the best in the business. Why trust your installation to a shoddy and time consuming kit? Our GSXL Turbowires are designed with the same philosophy in mind.
