Description
Stock breather systems restrict airflow and allow oil vapors to recirculate inefficiently, robbing your M8 of clean air and consistent performance. The ARLEN NESS 10-Gauge Stage-1 Big Sucker eliminates these restrictions with a patent-pending hidden backing plate design that routes breather gases directly into your throttle body, improving throttle response and engine breathing. This is a bolt-on upgrade that delivers measurable gains in air quality and engine efficiency without fabrication or custom tuning.
