Injen Technology designed and produced the world’s first tuned air intake system and holds four (4) patents on the tuning process of an intake system – something no other manufacturer can claim. The SP series of cold air intakes feature many of Injen Technology’s patented tuning process, including MegaRam (MR) Technology (Patents 7,359,795 and 7,669,571), Air Fusion (Patents 7,757,548 and 7,721,699), and many other innovations that keep Injen Technology at the forefront in the performance aftermarket. This allows all of our intake systems to produce exceptional horsepower and torque gains right out of the box and without the need for expensive aftermarket tuning. Other intake manufactures are unable to make this claim and must use costly aftermarket tuning to correct poor fuel trim levels and check engine lights caused by their intake systems.
