Important Cold Air Intakes Benefits
Improved In Airflow – After market air intake systems collect air from outside the engine compartment, allowing the engine to breathe better. Locating the filter near the upper wheel well provides a better, unrestricted airflow than the factory-installed system.

Improvements In Fuel Economy – Because cooler air contains a higher percentage of oxygen, fuel economy will be increased. That will result in a more fuel-efficient burn, increasing overall fuel economy.

Improved Engine Roar – A more aggressive roar will be heard when a cold air intake system is installed. Some systems are quieter than others, so you must take that into account when you make your choice of systems. Are you after that really throaty roar or do you want a softer, muffled rumble.

Increased Throttle Response – Cold air intake systems can improve horsepower anywhere from 7-18 HP. With more horsepower available, the engine will provide a better throttle response and an increased acceleration potential when you step on the gas.
Best Cold Air Intake for Increased Throttle Response: Sinister Diesel SINSDCAI160
Sinister Diesel SINSDCAI160
Performance is the name of the game and with this Sinister Diesel cold air intake you will feel an immediate improvement in your 6.0 Powerstroke engine. It has a mandrel bent aluminum, powder-coated Sinister’s Signature Blue with an oversized cotton media filter that is washable and reusable. The Sinister intake will significantly improve throttle response and turbo spool-up.
Many drivers are concerned that a metal intake tube will result in the air being warmed as the metal becomes heated. The fact is that although Sinister’s aluminum tube will conduct heat better because it is metal, it will also dissipate that heat quicker than a plastic tube that takes more time to release built-up heat (known as heat soak). It is an easy install, looks great under the hood, and makes that awesome engine sound you are hoping for.
