Koyo Aluminum Filler Neck 13-16 Scion FR-S / Subaru BRZ

Koyorad introduces an all-aluminum coolant filler neck for the 2013-2016 Scion FR-S and Subaru BRZ. This is an all-aluminum upgrade to the stock plastic piece with many features built into the design.

• 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

Note: Will only fit with Koyorad SK-C13 or any equivalent deep plunger style cap (OEM cap will not fit, cap not included.)
