The S&B cold air intake is the best intake you can buy for your Ford 7.3L Powerstroke diesel engine.
The Ford 7.3L Powerstroke diesel engine is pretty fantastic from the factory. But, like any turbo charged vehicle, improving the air flow on the intake and exhaust side always provides improvements. The OEM airbox on the my Ford F250 is a little bit restrictive. In order to improve airflow and efficiency, I upgraded to an S&B cold air intake that is made for the 7.3L diesel engine. The better flowing intake makes the engine much more efficient in moving air. This results in improved gas mileage and drive ability. The intake is simple to install and provides noticeable benefits over the stock unit. Combine the S&B cold air intake with the MBRP exhaust and you have a great combination to improve the power, MPG, and efficiency of your 7.3L diesel engine!
