We were recently invited out to Edge’s Ogden, Utah, headquarters to validate its emissions-friendly Evolution CTS for 2007½ to 2009 Dodge Rams.

Edge Products is offering GM Duramax engine owners a shot at upgrading their oil-burner with its new Insight CTS3 and Evolution CTS3 kits.

The all-new Edge Products Insight CTS3 retails for $399.99, which we think is a good deal for the speed and improved user experience it provides.
