850cc BMW E36 M3 SouthBay Fuel Injectors - Set of 6
Big flow for big boost. Our 850cc SouthBay fuel injectors are the ultimate fueling solution for high-horsepower 1995-1999 BMW E36 M3 builds. Engineered for forced induction applications and E85 conversions, these injectors provide the massive flow necessary for S50 and S52 engines pushing the limits of the stock block and beyond.
Engineered for High-Output S5X Builds
When your E36 M3 moves beyond basic bolt-ons, fueling becomes your most critical component. The 850cc SouthBay Fuel Injectors (approximately 80lb/hr) are designed to provide consistent, high-volume fuel delivery without sacrificing the low-end pulse width control needed for street drivability.
Key Features:
-
High-Boost Ready: 850cc flow rate provides the overhead needed for high-horsepower turbocharged and supercharged S50/S52 engines.
-
Superior Atomization: Modern internal architecture ensures a fine fuel spray pattern, which is crucial for preventing cylinder washing and promoting efficient combustion.
-
Precision Flow Matching: Each set is flow-matched within 1% at both static and dynamic flow rates to ensure perfect cylinder balance.
