The Verus Engineering Windshield Washer Fluid Reservoir for the 2nd generation GR86/BRZ is designed to be a simple and cost-effective way for you to retain the washer fluid system when using a brake cooling kit or forced induction kit. The kit holds up to 1 liter of washer fluid while leaving room for your cooling ducts or charge pipes. We designed the reservoir to utilize the OEM pump gaskets, and filler neck for guaranteed fit and functionality. The parts are installed easily in factory locations and look like a factory component. Lastly, these are made in-house here in Indianapolis, Indiana, and anodized black for corrosion resistance and a lifetime of use.
