Radium Engineering Top Feed Injector Seats

Part #: 20-0444

Overview

The Radium Top Feed Injector Seats are precision-machined aluminum components designed specifically for Mazda 13B-RE, 13B-REW, and 20B-REW rotary engines.

They are engineered to seamlessly "pop" into the OEM injector bore, providing a secure and reliable seal. Whether you are upgrading your fuel system or performing a rebuild, these seats ensure proper fitment and sealing, supporting optimal fuel delivery and engine performance. They are compatible with or without OEM fuel injector diffusers, offering flexibility for various setups. Crafted from durable aluminum, these seats are built to withstand the demanding conditions of high-performance rotary engines, helping maintain consistent fuel pressure and response over time. Designed for enthusiasts and professionals alike, they facilitate precise injector installation and contribute to a cleaner, more efficient fuel system.
