Injen SP Cold Air Intake System – Toyota GR Supra A90 / BMW Z4 G29

OVERVIEW

The Toyota GR Supra is quick from the factory, but the OE intake tract on the A90 is heavily restricted and chokes the turbo before the engine can make its full output. Injen's R&D team took the car into the lab and developed the SP2300 around a large 4.0" mandrel-formed 6061-T6 aluminum intake tube that opens that tract up and lets the turbo and engine breathe.

The SP series is Injen Technology's flagship traditional aluminum intake line, and the SP2300 was engineered for the cleanest installation on the market. The tube gives a smooth, uninterrupted path for highly efficient airflow, and Injen confirmed that a safe air/fuel ratio is maintained throughout the power band. On Injen's dyno the SP2300 produced an additional 15 horsepower and 17 lb-ft of torque.

Air is drawn through a fully serviceable Injen SuperNano-Web dry filter, which adds filtration surface area for greater airflow without an oiled media, and a purpose-built heat shield isolates it from underhood heat. The system adds an aggressive intake growl as the turbo spools, and is offered in three finishes: SP2300P polished, SP2300WB wrinkle black and SP2300WR wrinkle red. Backed by the Injen Technology Limited Lifetime Warranty.
