Improving engine performance often starts with something fundamental: getting more usable air into the engine.

Injen Technology has built its reputation around developing tuned air intake systems rather than treating an intake as nothing more than a replacement filter and tube. Its engineering approach combines airflow design, intake tuning, filtration, and vehicle-specific fitment to create complete induction systems for a wide range of applications.

Today, Injen's product range extends beyond traditional intake systems to include throttle controllers, replacement filters, and select exhaust components.

Tuned Air Intake Technology

Injen's intake systems are engineered around the behavior of airflow inside the intake tract.

The company's patented technologies include MegaRam and Air Fusion, which are incorporated into various Injen intake designs. These systems are developed and tested to optimize airflow while maintaining appropriate air-fuel characteristics for the supported application.

This engineering philosophy is central to the brand's SP and Evolution product lines.

SP Series Intake Systems

The SP Series represents one of Injen's flagship lines of traditional aluminum intake systems.

SP systems use 6061-T6 aluminum intake tubing designed to provide a smooth airflow path, along with Injen SuperNano-Web dry air filters on many applications. Application-specific heat shields and other components are used where required to help separate the intake from engine-bay heat.

The SP lineup covers a wide variety of vehicles, including Toyota, Honda, Subaru, Lexus, Volkswagen, Kia, Hyundai, and other applications.

Evolution Cold Air Intake Systems

The Evolution Series takes a more enclosed approach to air management.

Depending on the application, Evolution systems can incorporate a molded intake housing, integrated ram-air scoop, large SuperNano-Web dry filter, and a dyno-tested aluminum intake tube.

The result is a complete intake assembly designed around both airflow and the management of the air entering the system. Injen's Evolution range includes applications such as the Toyota Tacoma, Toyota 4Runner, Toyota Tundra, Toyota 86/Subaru BRZ, Volkswagen Golf, and other vehicles.

Power-Flow Air Intake Systems

Injen's Power-Flow lineup provides another approach to intake upgrades, with application-specific systems available for vehicles such as the Toyota Tacoma, Toyota Tundra, and Ford F-150.

These systems combine Injen's airflow engineering with application-specific tubing, filtration, and heat-management components.

The XPH catalog includes Power-Flow systems in different finishes and configurations depending on the vehicle.

X-Pedal Pro Throttle Controllers

Injen's product range isn't limited to intake hardware.

The X-Pedal Pro throttle controller is designed to modify throttle response, giving drivers the ability to change how quickly the vehicle responds to accelerator-pedal inputs.

XPH carries X-Pedal Pro applications for vehicles including the Toyota Tacoma, Audi A4, Volkswagen GTI and Golf R, Kia, Hyundai, and other supported platforms.

Performance Air Filters and Filtration

The air filter is an important part of any intake system.

Injen uses SuperNano-Web dry filters in many of its intake systems. The design provides a large filtration surface while maintaining airflow through the intake system.

Replacement filters are also available for supported Injen applications, allowing owners to maintain their existing intake system without replacing the complete assembly.

Select Exhaust Applications

Although intake systems make up the majority of Injen's catalog, the brand also offers select exhaust products.

XPH currently carries Injen exhaust hardware including the stainless-steel cat-back exhaust for the 2013-2020 Toyota 86/Subaru BRZ, giving owners of these platforms the opportunity to complement their intake upgrade with an exhaust-focused modification.

Broad Vehicle Coverage

One of the strengths of the Injen catalog is its wide application coverage.

Products available through XPH include applications for:

• Toyota
• Lexus
• Subaru
• Volkswagen
• Audi
• Ford
• Honda
• Kia
• Hyundai
• Nissan
• Chevrolet
• And other supported platforms

Applications range from performance cars and compact vehicles to trucks and SUVs, including the Toyota GR-oriented enthusiast market, Tacoma, Tundra, 4Runner, Corolla, Camry, Volkswagen Golf and GTI, Subaru BRZ, Ford F-150, and numerous other vehicles. Exact fitment varies by product, engine, chassis, and model year.

Designed and Manufactured in the USA

Injen states that its intake systems are developed and manufactured in Pomona, California, with in-house dyno testing used throughout the development process.

The company's testing approach allows its engineers to evaluate airflow and performance characteristics for individual applications rather than relying solely on generic intake designs.
