N55 INTAKE - E-SERIES 335i 335xi 135i

The ARM N55 Intake is a complete induction solution for the N55-powered E-Series BMW. From the turbo to the air filter, the whole system is redesigned to improve airflow and turbo spool — shortening the induction path by 68% versus OEM by moving the filter behind the headlight, much closer to the turbo.

Highlights

• Gains of up to 11 whp.
• Precision-machined turbo inlet.
• Faster turbo spool and increased turbo sound.

Construction

The redesigned turbo inlet inserts into the OEM turbo with factory-like precision, then expands rapidly to 3" and holds that diameter all the way to the high-flow filter. Where the OEM inlet necks down to 46mm, the ARM inlet measures 75mm — a 63% increase. The oval high-flow filter offers a full 124 cubic inches of surface area, sized to fit between the headlight housing and coolant tank. The intake runner relocates the MAF sensor on a CNC-machined flange, includes a PCV port for the factory PCV system, and uses an open-ended bracket to keep the filter secure. A plug-in MAF extension harness means no cutting or splicing.
