OVERVIEW

The Goldenwrench Blackline Performance GR Corolla / GR Yaris G16E-GTS Engine Cap Set is the world's first five-piece billet engine cap set engineered specifically for the G16E-GTS turbocharged engine. Designed and produced entirely in-house, this Edition Red set replaces and upgrades the stock plastic engine caps with CNC-machined T6 aluminum components—delivering a cohesive, motorsport-inspired engine bay that matches the GR platform's performance pedigree.

Each cap in the set is formed from T6 aluminum and anodized in Edition Red—a finish chosen to complement the red accents found on the factory engine cover. All logos and branding are machined using advanced 3D milling rather than decals or stickers. The five-piece kit covers the oil cap, coolant tank cap, coolant tank bleeder screw, brake master cylinder cap, and fuel cap for a unified visual upgrade across the engine bay.

Installation is straightforward: the billet oil cap and coolant bleeder screw are direct full replacements, while the coolant cap, brake master cylinder cap, and fuel cap are precision covers that affix cleanly over the factory units using the included hardware.
