The Ford Powerstroke 6.4L 2008 to 2010 model years have somewhat restrictive air intake systems. The truck would greatly benefit from an air intake that supplies the engine with the air that it needs. You would notice improvements across the board; horsepower, torque, and mileage. Your truck would feel better, and an open air intake system would be an excellent support mod for further modifications. A perfect pairing that would create an efficient system would be an air intake combined with a tuner and an exhaust, products you can also find on HeavyWeight Diesel.
An aftermarket air filter would indirectly protect your Powerstroke by filtering contaminants such as dirt and debris. Next to your engine being supplied with cleaner oxygen, you won't have to worry about oil contamination. It's important to consider the environment you're in before purchasing an air filter and we at HeavyWeight Diesel stock air filters for every environment. If you're uncertain of which air filter you need, we invite you to contact our technicians for help!
