Spoon reservoir tank cover serve three purposes. One, they help keep the reservoir tanks caps in place during racing and spirited driving, helping prevent spillage of vital fluids. Second, even if the caps are jarred open, the tank covers help contain the spill and minimize fluid loss.

Furthermore, they help prevent the brake fluid from adsorbing moisture from the atmosphere, which otherwise reduces braking performance and causes corrosion of brake components.
Reservoir tank covers are sold in packs of 1.
