## Description

We at Metra always strive to listen to our customers. You have told us to do a better job at telling the Metra sto ry. For over 70 years, Metra has maintained its cutting edge by paying attention to our marketplace and innovating products to fit the needs of the installer. We are the "Installer's Choice" because we are installers. We design our products to be easy to use and easy on the eyes. If you can see a Metra product, then we haven't done our job. 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. Their longer length for ease of installation and thicker OEM cables with OEM connectors make for a mighty install, with no down time on returns or angry customers.

Review: Be Careful - This just arrived after waiting patiently for its arrival from the USA. Unfortunately this does not fit the Ford Explorer 05 as stated. Good quality item, but clearly a waste of time and money as seller is USA based, this isn't worth a return!
