AMSOIL Introduces
Injen/AMSOIL
Co-Branded Diesel Air Intake Systems

AMSOIL has established a business partnership with Injen Technology, Inc. to provide three new air intake systems for diesel trucks. This partnership offers AMSOIL Dealers exciting opportunities for increased sales in the booming diesel market.

Market History
Aftermarket air intake systems hit the market in the late 1980s. They were originally constructed of rotationallymolded plastic intake tubes and primarily used wet cotton gauze air filters. In the late 1990s, several additional U.S. and foreign firms developed new air intake systems, greatly expanding the market. Many intake systems today are still constructed of plastic tubes and use wet cotton gauze filters, although some companies now offer systems in metal tube designs.

This history of Injen Technology, much like the history of AMSOIL, is a classic success story of a small manufacturing company turned industry leader. In 1998, Injen embarked on a quest to brand its name and set new standards of quality and performance while striving to improve its engineering capabilities. New products were introduced through the years and in 2005, the new line of Injen products was displayed at the SEMA trade show, winning the International Product Award. Injen products generate excitement among consumers, making Injen a great partner for AMSOIL.

Intake System Design
Cold air intake systems serve several important functions. Primarily, they are used to increase the amount of oxygen available to the engine, increasing power. Because cool air has greater density than hot air, aftermarket intakes improve combustion of fuel by capturing cooler air from outside the engine compartment. In addition, an aftermarket air intake system increases the diameter of the intake as compared to the original equipment, increasing air flow into the engine and making more oxygen available during the combustion process.

By designing a more direct route for the air entering the engine, as well as a smoother interior surface for the intake, air resistance is reduced and air flow is increased. To protect the engine from damaging dirt, cold air intakes are also equipped with filters. Air intake systems can improve gas mileage and increase performance, and they also add a sleek, custom look to a vehicle.

Construction of Injen/AMSOIL Diesel Air Intake Systems
AMSOIL now offers the Injen/AMSOIL Power-Flow Diesel Air Intake series with revolutionary Variable Induction Technology. The new VI Technology process is a multipower air induction system that fills the plenum with air, giving added power on demand. The Power Box on the Diesel series is manufactured using a composite mix of glass-filled nylon and polypropylene designed for noticeably quiet operation. The Power Box was designed for advanced cooling efficiency and the ability to resist high temperatures. It will not distort, unlike other plastic components that lose their structural integrity over time. This ground-breaking material makes it possible for the integration of a built-in velocity stack that streamlines the air turbulence into the plenum air chamber by way of the multi-power induction system.

Injen/AMSOIL Diesel Air Intake Systems are manufactured with aerospace alloy T6 aluminum, stainless steel clamps and tig-welded ports and brackets. They are dyno-tuned for peak performance and have a direct boltin application, making installation quick and easy.

AMSOIL Ea Air Filters and Injen
The addition of AMSOIL Ea Air Filters to these high-quality intake systems ensures the ultimate in protection and performance. Injen recognized the unsurpassed quality of AMSOIL Ea Air Filters and sought partnership with AMSOIL in order to make the best product possible. AMSOIL designed, developed and manufactured special EaA Diesel Intake Filters for the system.

AMSOIL Ea Diesel Intake Filters provide increased horsepower and torque, improved acceleration and fuel economy and maximum air flow. The high quality of the AMSOIL Ea Filter media offers long filter life because the filters can be cleaned and reused. Above all, Injen/AMSOIL Filters provide superior protection and maximum efficiency for engines.

AMSOIL now offers Injen/AMSOIL Power-Flow Diesel Intake kits for the following applications:
