Koyorad All Aluminum Radiator Filler Neck - 2013+ FR-S / BRZ / 86

Koyorad introduces an all-aluminum filler neck for the 2013+ Scion FR-S, Subaru BRZ, and Toyota 86.

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

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