Moderate — 2–4 hours
Description
This kit replaces restrictive factory plastic parts with a high-flow, fabricated aluminum intake pipe and air box for improved engine performance. It increases airflow to the turbo, potentially boosting horsepower and torque, and provides quicker throttle response. The system draws cold air through the hood ram air duct and inner fender, leading to cooler intake temperatures.
