Injen SP Cold Air Intake SP1123 – BMW 230i / 330i / 430i (B48)

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). Both are built into the SP1123 for BMW's B46 and B48 2.0L turbo four.

The kit replaces the restrictive factory airbox with a 6061-T6 aluminum intake tube that gives the turbo a smooth, uninterrupted path to the compressor inlet, and adds a heat shield built specifically for this chassis to keep the filter separated from radiant underhood heat. Injen developed the system on the dyno for gains of up to 13 horsepower and 12 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 system delivers an aggressive, throaty tone under full throttle. Made in Pomona, California and backed by the Injen Technology Limited Lifetime Warranty.
