Koyorad introduces an all-aluminum filler neck for the 2013-2020 Scion FR-S / Toyota 86 / Subaru BRZ (ZN6/ZC6). This is an all- aluminum upgrade to the stock plastic piece with many features built into the design:

- Billet aluminum eliminates steam erosion and cracking common with plastic filler necks
- Integrated 1/8 PT sensor port (supplied with optional plug) to fit with sensors provided by most Japanese temperature gauge companies
- Conversion of radiator cap style to the more durable deep plunger type - Koyorad # SK-C13 or equivalent (OEM cap will not fit, cap not included)
- Direct replacement for a quick installation; a direct replacement for the stock plastic filler neck and can use the OEM hoses and clamps
