The K&N High-Flow Intake System for the 2013 Scion FR-S & Subaru BRZ 2.0L, (P/N 69-8619TS) increases horsepower by an estimated 7 hp at 6670 rpm over the stock intake configuration. To achieve such a performance increase, K&N replaces the original intake assembly; including the air box, air filter and intake tube with an all-new intake design. The new system draws air through a K&N High-Flow Air Filter that increases airflow and never needs to be replaced. Protecting the cone-shaped air filter, and isolating it from engine heat, is a powder coated heat shield that replaces the stock air box. As it passes the filter, air travels through a K&N mandrel bent aluminum tube that is formed and shaped, in the design phase, to drive a more laminar flow of air to the car’s engine.
