Goldenwrench Blackline Performance A90 Supra Coolant Cap Cover Set

The Goldenwrench Blackline Performance A90 Supra Coolant Cap Cover Set delivers a matching billet upgrade to both the coolant expansion tank and the heat exchanger coolant tank on the 2020+ Toyota GR Supra (A90). Following the success of the Blackline Billet Oil Cap Cover, this set brings the same precision engineering and in-house manufacturing standards to the factory plastic coolant caps — covering both locations for a cohesive engine bay appearance.

Each cap cover in the set is CNC-machined from high-grade T6 aluminum and anodized in a race-inspired Edition Red finish that complements the accent stripes on the factory engine cover. All logos and design details are created using a precision 3D milling process, machined directly into the aluminum surface for a permanent, high-definition finish. The Blackline insignia is integrated into each piece to maintain a consistent aesthetic across the engine bay.

These are covers, not full cap replacements. Each piece affixes directly over the existing factory coolant cap in minutes, requiring no tools or modification. Every set includes both the coolant expansion tank cap cover and the heat exchanger coolant tank cap cover, along with an installation instruction card.
