2003-2007 Ford F250 & F350 Sinister Diesel Cold Air Intake | SD-CAI-6.0

Performance-Ready Intake System

The 2003-2007 Super Duty's 6.0L Powerstroke diesel is a capable engine with the right modifications, but if you have made any upgrades to your engine, you need an air intake system to accommodate for the extra power demands. Sinister Diesel has been in the game for a long time, and their cold air intake kits are testament to their commitment to quality and innovation. Let us be clear, if you're looking for an intake system for simply replacing your stock component and maintaining factory power levels and efficiency, look elsewhere. This complete intake system is an all-out performance and efficiency upgrade in the form of a cool blue cold air intake. Constructed from high quality aluminum, the unique design and material provide ultimate heat dissipation and airflow to keep your engine cool no matter how hard you push that 6.0L Powerstroke.

Improved Durability

A few folks will tell you that aluminum intakes absorb heat quicker, and that's true, but it's also true that aluminum lets heat dissipate much more quickly than plastic. Plastic has a tendency to "soak" all that heat in (heat soak) and never let it go, unlike aluminum which allows for a cooler running temperature and therefore better performance. Another major benefit to this aluminum cold air intake is its insane durability. Along with incorporating high quality aluminum, Sinister uses a premium silicone to construct its couplers instead of the cheap rubber you see on other kits. And to ensure it all gets put together right, Sinister manufacturers its cold air intake kits in-house to ensure minimal fitment variability and rigorous quality control processes. With this bad boy installed, you'll never have to worry about warping or cracking, ensuring long life and lasting dependability.

Easy Installation

Performance, efficiency, and durability were clearly on the top of Sinister's priorities when they designed this cold air intake system, but thankfully they've managed to pack all of that quality into a simple and easy-to-install package. Proper installation shouldn't take more than a couple of hours with standard tools and minimal experience. Better yet, they include a complete instruction manual as well as all necessary couplers and clamps!
