You have your horses loaded in your trailer and your Ford Powerstroke or Dodge Cummins is struggling for air and just doesn't have much power it seems. One of the very first things that you can do to increase performance is to replace your factory air filter and filter box with an Cold Air Intake. There are other things that you can do but by making this change and installing a Cold Air Intake what you are doing is giving your Diesel more air from a cooler source outside the engine compartment. Hence your Cummins or Powerstroke will have access to denser cooler air and less restrictions and this means not only more horsepower but better gas mileage.
An Icebox Cold Air Intakes is one of the best investments that you can make for your Diesels performance. Check them out today! You will be happy you did!
