The AIRAID Jr. Kit targets the restrictive elements of factory intake systems, the intake tube and the paper filter, in order to help boost horsepower and mileage. This air intake system offers a simple, economical introduction into the performance aftermarket with the introduction of an AIRAID Premium Direct-Fit Replacement Filter and an AIRAID Modular Intake Tube. As with other AIRAID intake systems, the AIRAID Jr. Kit helps to straighten and improve clean air flow to the engine for added throttle response and increased horsepower and torque. Each kit is custom made to fit specific vehicles and is easy to install and requires no drilling. Unlike stock paper filters, AIRAID Direct-Fit Replacement Filters are washable, reusable and fully backed by the AIRAID No-Hassle Lifetime Warranty. Some AIRAID air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.
