I've had it on my wife's gmc Yukon for 2 weeks no more using oil and no more check engine light. So far so good!

Got this for my boyfriend for christmas. It was super easy to install, adds a couple HP to the truck, saves gas, and it very easy to understand. Overall a great product for a very good deal.
