Radium EGR Delete Kit - Toyota Supra JZA80 MK4 (2JZ-GTE)

Suits:

• Toyota Supra JZA80 (MK4) — 2JZ-GTE (EGR-equipped models only)

⚠️ Off-road and competition use only. This product does not meet emission standards and must not be used on public roads.

The exhaust gas recirculation (EGR) system transfers hot exhaust gases back through the intake manifold to lower nitrogen oxide emissions. However, the EGR inevitably increases intake temperatures and dilutes the oxygen required to produce horsepower. This Radium Engineering EGR Delete Kit seals all related ports when the factory EGR system is removed — including ports in the intake manifold, cylinder head, and vacuum lines — cleaning up the engine bay and eliminating the need for factory Toyota EGR gasket replacements.

Features

• CNC-machined 6061 aluminium block-off plates
• Type-II anodised black finish
• High-temp silicone O-rings
• High-temp vacuum plugs
• Stainless steel bolts
• Eliminates need for factory Toyota EGR gasket replacements
• No permanent modifications required

Notes:

• Compatible with Toyota 2JZ-GTE engines that came standard with the EGR system only
