These Intake Systems Feature the Patent Pending MR Technology Process for Optimal Gains and a Safe A/F Ratio. The SP series intake for the 2009-2010 Nissan Maxima 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
For over a decade Injen Technology Co. Ltd and our sister company has played a major role in the design and development of air intake systems. Injen Technology is based out of California in the same city and just a few miles away from the famous Pomona Winter Nationals Top Fuel Raceway. Injen Technology's history is a classic success story of a small manufacturing company turned industry leader of aftermarket performance products.
A lethal tuning combination is what you get when you combine the patented MR step-down process with Air Fusion. You'll experience exhilarating gains of up to 8 h/p and 11 ft/lbs of torque by bolting on the all new SP1947. In addition, you get the Power-Packed, Web nano-fiber dry filter, the first surface-loading filter that not only aids in producing horsepower but also helps protect your engine from harsh and dirty environments.
