Active fuel management Range
Installed on 2010 5.7l Suburban, Engine was re-piston and ringed by GM. Abnormal oil consumption was the issue. Dealer service recommended this device and changing oil every 3K. I am now seeing no oil loss at 3K. As indicated on Dash engine stays in v-8 mode as it should with this device. Shipping was quick. Very Satisfied****
Range Active Fuel Management Device
I bought the Range Active Mgt Device for my 2009 Suburban. It was an easy install. Unfortunately it quit working within 2 months of installation and less than 1,000 miles. Auto Anything processed a return/exchange so I'm giving the device a second try. I am hopeful that it will work as advertised.
