Injen's Race Division™ intake systems are engineered to perform at peak level when horsepower and torque are called for! Each Race Division™ intake is CNC mandrel bent utilizing only the best aerospace alloys for a smooth, light-weight aluminum bend. Injen selects precise tube length, diameter and bend radius for each application to maximize air-flow and performance giving you one of the best engineered cold air intakes available in today's competitive market! When it comes down to fine tuning their intakes, they don't hold back; Injen seeks to meet and exceed their own demanding guidelines. Not only aesthetically pleasing, each kit comes equipped with hardware, vibra-mounts and CNC machined brackets that are tig welded to each intake for a perfect show-quality fit every time. Each cold air intake is then put to the test against Injen's leading competition and, to this day, Injen has yet to be outperformed... and they have the test results to prove it!
Revolutionizing the intake performance market one application at a time, our patent pending MR Technology Process is leading the way. With so many late models cars utilizing the best in technology, making safe, reliable power gains is a concern. These late model vehicles have very sensitive factory a/f ratios, MR Technology will not only allow the intake to be tuned within that factory ratio, but will optimize horsepower and torque gains all around. Through a step down process, MR Technology will regulate the airflow at certain strategic points, ultimately controlling the rate and density. By doing so, the MR Technology process tunes the intake system to avoid the necessity of calibrating MAF sensors. Overall, the MR Technology process was developed in order to compensate for the vast change in technology and the need for safe, reliable performance products.
This graph without the use of MR Technology, reveals a very unstable and lean air/fuel ratio while making high horsepower/torque gains.
When MR Technology is implemented horsepower/torque gains are maximized while air/fuel ratio becomes stabilized.
At our shop in Hayward, CA (Bay Area), we frequently dyno the new 06 and up Civic Si's, known as the FA5 for the 4 door Civic Si sedan and the FG2 for the Civic Coupe. A customer came to us with an FA5 Civic, and wanted us to install his Injen Cold Air Intake and then dyno the car to see the horsepower the car made. The install was simple, and straight forward. The car had about 5000 miles, and has no other modifications. The car made a peak of 193.03 horsepower at the front wheels, and 142.12 torque at the front wheels. Very good gains for a bone stock Honda Civic Si with an intake! An average FA5 Civic will dyno about 180 whp and 131 wtq.
