SP Series - All SP series intakes are manufactured using Injen's unique MR Technology. MR technology is a means of restricting the intake in a strategic location and maximizing airflow in other strategic points in order to supply maximum amount of air through the intake manifold while getting maximum injection from the fuel supply in order to hit peak, optimal gains. Unlike any other intake on the market, SP series intakes are tuned. Injen is the only manufacturer that offers vehicle, engine, and ecu specific tuning. Not only will the a/f ration be optimal, it will be safe on your engine. Most cold air intakes will run your engine too lean, causing damage and missing optimal gains. MR technology is the most superior technology on the market.

These Intake Systems Feature the Patent Pending MR Technology Process for Optimal Gains and a Safe A/F Ratio. The SP series does not limit itself to just a Cold Air System or Short Ram System. The MR Technology process has its effects on both types. SP is The World's First Tuned Intake System.
