Upgrading your vehicle's restrictive stock air box with Stillen air intake kits will allow for increased airflow, which can help your engine breathe better and more efficiently. Air intake systems, also referred to as cold air intakes, are popular performance modifications that can be installed on many vehicle classes, ranging from high-performance sports cars to hard-working diesel trucks. These air intake kit components are designed to replace your vehicle's factory intake assembly with aftermarket intake tubes, air boxes, and filters to overcome restrictions in the intact tract, thus allowing more air to enter the cylinders. With an air intake kit by Stillen, you can expect to see a positive effect on horsepower, torque, and acceleration, as well as improved fuel economy—and that makes Stillen's air intake kits your best dollar-per-horsepower investment by far!

Upgrading your vehicle's air intake can provide several benefits, including:

* Improved fuel economy—cold air intake systems can improve your vehicle's air-to-fuel ratio, which can lead to better gas mileage.
* Better acceleration, cold air intake systems can improve your vehicle's responsiveness and acceleration speed
* Increased airflow—upgrading your air intake can allow for increased airflow, which can help your engine breathe better and more efficiently
* Enhanced engine sound—increased airflow can create a sought-after engine roar
* Better air filter life—aftermarket air intakes often come with washable, reusable air filters that can last longer than standard dry filters
* Reduced engine wear—increased airflow can reduce wear on your engine
* Engine longevity—upgrading your air intake system can enhance the longevity of your engine
