If you don’t know what a CAI is, then you should first read our article right here. But if you do, have you ever asked yourself why do some of them come with enclosed airboxes?
As you know, stock intakes are equipped with special airboxes with an intake filter inside. Typically, they are made of plastic and have a rather complex shape, which directly affects air volumes entering engine cylinders. Such a system may look odd and inefficient to some – why can’t you simply attach the filter directly to a tube, saving your underhood space and increasing the airflow?
The air is extremely unevenly distributed in the under-hood space – there are areas where the air is almost as cold as outside, but the temperature near the exhaust manifold often exceeds several hundred degrees. Besides, when on the fly, the underhood air is moving, and a set of vortices is formed.
The combination of these factors leads to a quite uneven filling of cylinders with the fuel-air mixture, which naturally leads to power loss. Therefore, to create an area where the air will be distributed evenly, the intake filter is placed in rather large airboxes. They save the air filter from dirt particles by keeping out excessive engine heat and complement your vehicle’s engine, extending its powerband.
The more surface area your intake filter or airbox has, the better for your engine.
A CAI system is often the first thing that comes to mind when you feel like improving your vehicle performance. Such systems usually look clean, sporty, and stylish.
Their capacity is higher than that of a stock paper model. CAI systems use an extended intake tubing to draw air not from the hot engine bay but the outside into the engine. This is based on the fact that for any internal combustion engine, the temperature of the intake air is essential. The lower it is, the more density can be achieved, the higher the oxygen content needed for complete combustion, and therefore, the higher the power.
For conventional cars, this technical solution is hardly justified, but for pickup trucks, SUVs, and sports models with large, tight-packed turbochargers, the use of CAI provides a small but still tangible boost in performance.
What properties should a perfect air intake system have?
An intake system that fully meets all the parameters does not exist. A high-quality intake system should have an efficient intake filter that will protect the engine from dirt particles and dust, while improving the engine’s overall performance, throttle response, fuel mileage, horsepower, and torque.
Airflow restriction should be minimal, and the air should be cold and dense, which directly depends on the tube quality and design. The airbox should be large enough, durable, and made of non-heat-soaking material.
Those are just a few things to consider when choosing a proper CAI for your truck. Below we have gathered our list of CAIs for 6.7 Powerstroke for your consideration. We hope you will find what you need!

Review of the Top Cold Air Intakes For F250/F350 Ford Super Duty (6.7 Powerstroke)
S&B 75-5104 – Best 6.7 Powerstroke Cold Air Intake
This intake system was designed by S&B to feed maximum cold/dense air to your 6.7L Powerstroke with minimized air restriction. You can expect up to 37% better airflow than stock units can provide.
The intake features a fully enclosed airbox for heat/dirt protection and a large highly-efficient cleanable/reusable oiled filter with 8-layer cotton media.

Cold air, as opposed to hot air, will contain more oxygen, which means burning will be more efficient and economical. It may not be worth talking about the guaranteed tangible difference and high power increase, as it depends directly on CAI design and type, as well as engine tuning parameters, and the availability of replacement exhaust, tuning software (tuners /programmers), etc.
But the effect is definitely there! A properly designed quality cold inlet system will provide exactly what you expect. You can (and should) increase your engine power with a larger air supply.
