FR-S / GR86 / BRZ blank radiator cap (non pressurised)

The GKTECH blank radiator cap (non pressurised) is a direct fit for FR-S / GR86 / BRZ. These are commonly used when installing a swirl pot setup.

NOTE: These MUST be used in conjunction with a pressurised cap somewhere in your system. You can not use these standalone as a direct replacement for the OEM cap.
