Injen Short Ram Intake (Wrinkle Black) – BMW N55 (F2x / F3x / F87)

OVERVIEW

The SP series is Injen Technology's flagship traditional aluminum intake line. Injen produced the world's first tuned air intake system and holds four patents covering the intake tuning process, including MegaRam (MR) Technology (patents 7,359,795 and 7,669,571) and Air Fusion (patent 7,721,669). The SP1128 applies that development work to the N55 3.0L turbo six.

The system replaces the restrictive factory airbox with a 6061-T6 aluminum intake tube that gives the turbo a smooth, uninterrupted path to the compressor inlet. A custom heat shield with a matching cover is built specifically for this chassis, keeping the filter isolated from radiant underhood heat. Injen developed the intake on the dyno for gains of up to 13 horsepower and 11 lb-ft of torque while holding a safe air/fuel ratio across the power band, so no additional tuning is required.

Air is drawn through a fully serviceable Injen SuperNano-Web dry filter, which adds filtration surface area for greater airflow without an oiled media. The textured wrinkle black finish gives a stealth look under the hood, and the system delivers an aggressive, throaty tone under full throttle. Made in Pomona, California and backed by the Injen Technology Limited Lifetime Warranty.
