I just purchased a 2007 LE Frontier crew cab 4x4. I test drove it for a day and then decided to trade my gas hog Grand Cherokee! So far I love the truck it is averaging around 21 mpg. The day I bought it it I talked my wife into letting me purchase a Bully Dog Triple dog and a K&N performance intake it to maybe get me up to around 23 to 25 mpg. Is there anything that any Frontier owner should know? And does anyone have any experience with these two products? Also do all 4.0 liters have a little whine in the engine?
