Product Description
The Sinister Diesel Cold Air Intake is one of the most effective ways to wake up your 6.0L Powerstroke. The factory intake system is restrictive and holds back airflow, robbing your truck of performance. This kit solves that problem with a CNC mandrel-bent aluminum intake tube and an oversized, high-flow cotton filter designed to deliver maximum airflow to your engine.

The result is improved horsepower, torque, throttle response, and turbo spool-up, making your truck more responsive whether you’re towing heavy, daily driving, or hitting the track.

FAQ's
• Q: I know it is stronger and looks better, but doesn't aluminum conduct more heat than plastic?
• A: From a technical standpoint, aluminum will conduct heat a little better because it is metal, but the thin walled tubing allows the heat to dissipate from the moving air much faster. The issue with a plastic intake tubing is that while it takes just as much time to heat up, it takes a considerable amount more time to dissipate that heat build up, also known as heat soak, within the tubing.
