This system utilizes several features to maintain optimal flow for performance while minimizing turbulence. The kit uses a custom conical cloth air‐filter element and a CFD‐designed velocity stack leading to an unique airflow straightener grid which is specifically designed to smooth the incoming air flow as it passes the MAF sensor for precise readings. This eliminates the "dead spots" experienced by other aftermarket intakes due to turbulence.
In order to provide a system that looks as good on the outside as the technical advancements happening on the inside, we utilize a one piece design constructed from a high temperature plastic composite. Not only does this save weight compared to the previous metal design, the plastic composite material offers much better heat insulation properties that help keep intake air temperatures cooler.
The Air Box adds the benefits of a cold air intake to the performance of the SF Intake. The factory inlet directs cold air from the front grill to the air box, which encloses the SF intake. Likewise this unique design also separates rainwater from the intake air, eliminating the water ingestion issues that plague traditional cold air intakes.
**Note: Proper tuning is MANDATORY for this intake!! Use associated +Big SF OTS Maps or have your car tuned by a Certified Protuner**
