CSF Aluminum Filler Neck with 1.4 Bar High Pressure Cap for 2013-2025 Subaru BRZ, Toyota 86/GR86, and Scion FR-S (8044)

Fits select 2013-2025 Subaru BRZ, Toyota 86, Toyota GR86, and Scion FR-S models. This CSF auxiliary filler neck is a robust upgrade designed to replace the failure-prone plastic factory unit. Constructed from 100% TIG-welded aluminum and finished with a mirror polish, it provides superior durability and heat resistance for high-performance driving.

The kit includes a 1.4 bar high-pressure "mini style" radiator cap embossed with the CSF logo. This higher pressure rating raises the boiling point of your engine coolant, improving thermal efficiency during track use or spirited driving. It also features an integrated 1/8 NPT sensor port, allowing for the easy addition of an aftermarket water temperature sensor without additional adapters.
