Injen Cold Air Intake: G35 Coupe 03-06

The Injen SP intake is The World's First Tuned Intake System. These Intake Systems Feature the Patent Pending MR Technology Process for Optimal Gains and a Safe A/F Ratio.

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.
