Description

The Koyo FN3037 is an aluminum filler neck designed for the 2022 Subaru BRZ and Toyota GR86. This direct replacement part is crafted from billet aluminum to prevent the steam erosion and cracks often found in plastic filler necks. It features an integrated 1/8 PT sensor port for compatibility with most Japanese temperature gauge sensors and is designed to accept a deep plunger-type pressure cap.
