30-Day Money-Back Guarantee

PROFILE

When we set out to develop the ARM F80 intake system we wanted to create an intake system for the S55 engine that would support the most advanced builds by removing any potential bottleneck in the induction system.

BUILT FOR PERFORMANCE

The focus of the ARM S55 Intake is performance, period. It looks good, it sounds amazing, and most importantly it makes your S55 breathe better. With a 3.5" inside diameter intake runners, the ARM S55 Intake System is the largest diameter intake system available for the S55 engine. Whether you're running the stock turbos or upgraded turbos, if you're looking for serious performance, the ARM S55 Intake system is your answer. Our project F80 M3 is equipped with Pure Turbos Stage 2+ turbochargers to test the limits our S55 upgrades.

CONSTRUCTION

The ARM S55 Intake is constructed of 6 layer reinforced silicone tubing. The passenger side maximizes the size of the large 3.5" air filters while making a smooth, uninterrupted transition down to the stock S55 turbo inlet. While the driver-side intake runner maintains the 3.5" inside diameter all the way until it reaches the stock turbo inlet and overlaps it, making the stock inlet pipe the lowest common denominator in the intake system. The ARM S55 Intake driver side runner is larger than even the upgraded Pure Turbos turbo inlet. PLEASE NOTE: You may experience mild fluctuating rpm on startup, this is common and will subside after approximately 15-30 seconds.
