Radium Engineering Toyota Injector Seats - 2JZ-GTE / 1JZ-GTE / 3S-GTE - 14mm Bore (Single)
Radium Engineering produces precision fuel system components trusted by tuners and race teams globally, and these injector seats are a direct example of that standard. CNC-machined from billet 6061 aluminium and bright-dip anodised for durability, they are the same seats Radium uses in their own fuel rail kits — purpose-built for converting OEM side-feed setups to top-feed injector configurations on popular Toyota engines.
This listing covers a single injector seat (SKU: 20-0216) compatible with the Toyota 2JZ-GTE, 1JZ-GTE, and 3S-GTE engines, as well as other Toyota engines sharing a 22mm injector counterbore. Order one seat per injector position.
Note: Sold individually. Confirm your engine's injector counterbore dimension is 22mm before ordering. For other Toyota applications not listed, verify fitment prior to purchase.
Key Features
- CNC-machined 6061 billet aluminium construction
- Bright-dip anodised finish with laser etched Radium logo
