Mileage on your truck should increase by about 1-2 miles per gallon. Please wait a while to determine how your mileage has been affected. Your driving style has much to do with your mileage and that can be affected drastically by an excited driver.
Included with your nozzles is a nozzle removal tool to help you change the nozzles. This tool gets clamped in a vise and holds the injector so you can easily remove the nozzle. Also included in the box are color instructions, a set of copper washers and a core return form. Please return the nozzle removal tool with your core nozzles for a full refund.
As always, this product is covered by our 3 year unlimited mileage warranty and our 30 day money back guarantee. Please see our Policies section to read more.
Important!!!There are 2 extremely important tips that we must give you before you or anyone works on your 6.7. First, there are very tiny steel disks inside your injector under the nozzles. Be EXTREMELY careful not to loose these, they can get away before you know what happened. They are very small. Secondly, make absolutely sure you label each injector and make sure it goes back into the same cylinder. The 6.7 is programmed to learn each injector and will reject the incorrect injector if the order is mixed up.
