- Check your air filter!
- All diesel engines move a tremendous amount of air. If your fuel mileage is dropping or you see black smoke, this is the first place to look
- If you have an "open" air filter (not enclosed), you might want to look into an airbox. For stock turbos, you can swap in a 1997+ RPO Code K47 airbox, or, take a look at the S&B Airbox with dry or washable elements
