REVIEWS YOU CAN TRUST 

We strive to always give you genuine, accurate information. To do this, all of mechanicguides.com reviews are based on market research, expert input, and practical experience.

Ever since the mid-1990’s when advanced emission controls were brought into line with EPA considerations, the older thermostatic intake units were replaced with advanced fuel injection systems that do not regulate the air temperature flow. As such, aftermarket air intake kits are becoming more and more attractive to drivers that want to upgrade their vehicles performance in all operations.

Cold air intake kits might not add a lot of power, but they do add a little bit, and for not a lot of extra cash you can improve the overall performance of your vehicle, which might mean the difference in a racing environment.

Since you remove the filter from the engine and create a cold air induction environment, you essentially enable your car to burn more oxygen in every feed and produce a more powerful stroke with every turn of the crank. The filter also provides cleaner air and reduces emissions in some specific models.

Here is a list of the ten best cold air intakes for your Ford 7.3 Powerstroke engines.

Conclusions

In the world of performance and racing, every small additional power you coax out of your engine is worthwhile adding. This includes even the banalest of upgrades, and one of the simplest of these are adding a cold air intake kit.

When you add an aftermarket air intake kit you will immediately notice the difference in performance, and also notice balanced engine temperature performance that leads to longer engine life. There is a definite impact on fuel consumption, as well as a reduction in engine wear and tear on all components.

Since all aftermarket models are built for specific applications, you are limited to what your engine can use. As such, you need to check your exact model and then buy the air filter upgrade that best suits your needs. Take into account that some kits will require body modifications, so if you are into a complete upgrade, including manifolds, exhaust systems and more, then adding a new cold air intake kit is an obvious inclusion.

If you are only interested in increasing some power and maintaining your engine, then a budget-friendly synthetic system will be more than enough for your purposes.

There are different materials, but essentially a cast aluminum body and piping will provide the best cooling properties to your engine, and if you are into performance and racing, you must concentrate on a kit that is made of aluminum. If you want to go one step further, then pair your performance air intake with a mass air flow sensor and link it to your dashboard computer.

A final word, cold air intakes are not pipes with filters stuck on the end. A cold air intake system is an especially CAD designed, and each intake tube is created for specific air flow, and the filter body is created to reduce air turbulence while maximizing air intake through smart filter shape. As I stated above, the best systems have mandrel bent pipes, made of metal, and aluminum is your best choice.
