Goldenwrench Blackline Performance GR Corolla / Yaris (G16E-GTS) Cap Set - Edition Red

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 the factory plastic engine caps with CNC-machined T6 aluminum components finished to the same precision standard as every piece in the Blackline lineup — delivering a cohesive, motorsport-inspired engine bay that matches the GR Corolla and GR Yaris 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, not applied with decals or stickers. The five-piece kit covers the oil cap, coolant tank cap, coolant tank bleeder screw, brake master cylinder cap cover, and fuel cap cover — providing a unified visual upgrade across the most visible points in the engine bay. Note that only the billet oil cap and the coolant bleeder screw are full replacement units; the remaining three pieces are precision covers that affix directly over the factory caps.

Installation is straightforward. The two full replacements thread into place directly, while the three cap covers affix over the factory units using the included hardware. An Installation Instruction Card is included with each set, and the complete process takes only minutes per piece.
