Injen Cold Air Intake – BMW 135i / 335i / 335i xDrive (N54)

OVERVIEW

The SP series is Injen Technology's flagship line of traditional aluminum intake systems. Injen was the world's first tuned air intake manufacturer and holds four patents covering the intake tuning process. This kit carries several of those patented technologies, including MegaRam (MR) Technology (patents 7,359,795 and 7,669,571) and Air Fusion (patent 7,721,669).

At the center of the system is a 6061-T6 aluminum intake tube that gives air a smooth, uninterrupted path into the N54. A fully functional ram air scoop feeds cool air directly to the filter, and Injen tuned the system to deliver power while holding a safe air/fuel ratio across the power band, so no additional tuning is required.

A fully serviceable SuperNano-Web dry air filter provides increased surface area for greater airflow and strong filtration, and the system produces an aggressive, throaty tone under full throttle. The kit is offered in polished and wrinkle black finishes and is covered by the Injen Technology Limited Lifetime Warranty.
