Radium Engineering Intake Manifold Gasket | 2020-2021 Toyota Supra (18-0085)

Port injection on the B58 means the manifold comes off, and it should go back on a fresh gasket.

The Radium Engineering Intake Manifold Gasket for the MK5 Supra is the reseal part for the 2020+ GR Supra's B58: the manifold-to-head gasket that every port injection install, manifold service, and intake-side project on the A90/A91 should finish with, rather than gambling on the compressed original.

What You'll Feel

• The manifold resealed properly after the port injection install
• No vacuum leaks hiding behind a reused, compressed gasket
• Idle and tune stability that only a sealed intake tract delivers

Features

• Intake manifold gasket for the 2020+ Toyota GR Supra (B58)
• Service companion to Radium's MK5 port injection hardware
• Direct replacement fitment

The Details

Radium's MK5 port injection system lives at the manifold, with the 20-0753 rail and injector bungs going in behind it, and the gasket is the honest last line of that job sheet: seals compress once, and a manifold R&R on the original gasket invites the small vacuum leaks that read as lean idle codes and tune chasing. Keep one on the shelf per planned manifold removal, torque the manifold per BMW/Toyota's sequence, and the intake tract seals like the install never happened.
