Product Overview
The Ansix 4-2-1 race header is specifically designed for the FA24 engine in the new BRZ and GR86. It features larger runners to reduce restriction and optimize airflow for the higher-displacement motor. The header is CAD-designed to ensure perfectly equal runner lengths. Additionally, it is engineered to provide clearance for a large-capacity oil pan. Two flex joints are incorporated into the runners to minimize thermal stresses, helping to prevent weld cracks. Each header is hand-built using mandrel-bent 304 stainless steel tubing.
The Ansix large-capacity oil pan is specifically designed for use with the Ansix race header. It is fabricated from stainless steel and features a drain port positioned directly below the pickup tube, allowing for easy inspection of RTV debris during every oil change. The oil pan increases the oiling system capacity by an additional 2L and includes internal baffling to mitigate pressure loss during braking and right-hand turns.
While the header can be used independently, the oil pan cannot be installed without the header. Test data for the header and oil pan will be released at a later date.
