Injen Intakes & Exhausts





Injen Technology Co. Ltd is a living example of the American dream. Established in 1998, Injen absorbed all the experience and knowledge of its sister company RD Metal Works. Since the mid 90's, RD Metal Works has been manufacturing top-of-the-line air intake kits for major air filter and air intake manufacturers. To deliver products that are second to none, Injen uses only the most reliable techniques and the most advanced equipment.

The first air filter was designed by Injen in the faraway 1999. It was a urethane filter with a built-in velocity stack. That simple feature added a lot more to the performance of the filter. And that's how Injen works. They improve on the best down to the last detail. Injen is determined to deliver top-quality performance filters that have no equals when it comes to filtration and airflow efficiency, dust-holding capacity, and service life.

When a new filter is developed, the engineers calculate its pleat and mesh, ensuring optimum airflow. To make sure each filter offers superb filtration efficiency, Injen uses the finest cotton gauze as the filtering media. To prevent heat soak, the top and base of each Injen air filter are made of urethane. Injen high performance filters are designed to remain effective for 30,000-40,000 miles between cleanings. Best yet. Your Injen filter will serve you long. customers know that for sure.

It's no secret that some things simply work better. Take for example your exhaust system. An aftermarket exhaust offered by Injen is one of those things that are better, yet we consistently insist on making life complicated. We stick to the original parts, even though the restrictive design of the OEM exhaust will hardly let your vehicle perform to the best. Those who already have an Injen exhaust system know how dramatically it can improve the performance.

Injen Technology's Super SES exhaust systems are dyno-tuned with their intakes to deliver maximum gains in horsepower and torque. Each SES exhaust system is made from 304 stainless steel to ensure long service life. All the tubing is mandrel bent to make sure the inside diameter remains constant. And don't forget that Injen designs exhaust systems for each specific application so that the fit is just perfect.

Injen products are no doubt what every driver needs. Whether it is an air filter, or an air intake, or whatever concerning the exhaust system. Injen and its sister company RD Metal Works serve for nothing but the quality, taking into consideration design capabilities, too. Every Injen cold air intake met a strong favor from both American and Canadian customers as producing intakes for trucks, SUVs, and high performance automotive. The “World's First Tuned” and “Power Flow” air intakes were set off and soon accepted by consumers for the most innovative production technologies. New industry standards brought the Injen product lines a number of international awards.

Works and Sounds Great!!!
I used this filter 3.5in inlet with the stock piping along with a 3.25in inlet 6in connector to complete the install. Talk about a breath of fresh air. Love the look and the sound!!!

Know What You’re Buying
Like the title says, know what you’re buying. This means just because its a fancy tube does not means it’s a turbo and you will not notice any power gains from driving alone, on the dyno you might. Buy this if you are doing it for sound and engine dressing. It definitely makes your engine bay look better and it definitely makes the growl of the car more aggressive. It’s a great product for what it is, the bad reviews come from people that are expecting much more.
