When upgrading your vehicle's engine, the air intake is often first on the list for a number of reasons, but what are they exactly? From performance to sound and even money-saving advantages, we'll take a look at the benefits of upgrading your air intake and provide a list of top recommendations so you can rest easy and be confident in your upgrade.


Better Performance

An air intake serves as your vehicle's lungs, taking in air and distributing it to the engine's intake manifold. Upgrading the intake will allow for increased air flow, helping your truck breathe better and more efficiently. You'll see a positive effect on horsepower, torque, and acceleration as well as improved fuel economy. The numbers will depend on your engine, but you can expect to see increases between five to 15 horsepower.

Better Performance

Amplified Sound

Amplified Sound

Increased air flow is what creates that sought-after engine roar, and upgrading the intake will certainly heighten your truck's sound. You can amplify the sound even more with additional performance upgrades, such as a muffler and wider exhaust pipes.

Reusable, Money-Saving Filters

Most aftermarket air intakes come with washable, reusable air filters. They're typically made of cotton and are designed for maximum filtration, trapping debris of all sizes before it gets sucked into your engine. Their reusable nature is environmentally friendly and economical, saving you from having to purchase new filters. Check out our how-to on cleaning these filters. They also last longer than standard dry filters, with most backed by lifetime or million-mile warranties.
