Putting on a cold air intake will give your 6.0 Powerstroke more cool air and more power. This could result in better throttle respond, more turbo noise, increase fuel economy and more for the 6.0 Powerstroke. Some intakes are completely sealed from the hot engine air. These 6.0 air intakes are the most expensive but yet most effective. Our best selling intakes are the 6.0 S&B air intake and the 6.0 Banks Ram Air.
