Boosted reliability starts with strong, precise hardware. This stud nut kit is purpose-built for the Toyota Starlet EP82 and EP91 4E-FTE engines running the factory CT9 turbo setup. Whether you’re replacing worn studs or upgrading for performance use, this kit ensures a tight seal across all turbo and exhaust flange points.
Engineered with heat-treated medium carbon steel studs and inner hex ends for easy installation, paired with self-locking copper-plated flange nuts that resist backing out under high heat and vibration. Each kit is tailored to match OEM flange locations—no cutting, no guesswork.
