Really add some performance to your 2003 to 2007 Ford Powerstroke 6.0L engine without major modifications by using a cold air intake from Sinister Diesel. You get an original design with this 6.0L Powerstroke cold air intake, which results in quicker throttle response and turbo spool-up. You'll feel an immediate difference, whether you're just driving around town, towing, or racing. The CNC mandrel bent aluminum intake tube has a Signature Sinister Blue powder coat, so it looks great and will withstand some serious use. The oversized cotton filter can be cleaned and reused, so you don't have to keep swapping out filters. All mounting hardware comes included, and installation is a breeze.
