BMW M57 Fuel Injector Plug Connector

BMW M57 Fuel Injector Plug Connector

The BMW M57 Fuel Injector Plug Connector is an OEM‑style replacement/retrofit connector for M57 engine swaps and harness repairs. Built for reliability in high‑heat, high‑vibration environments, it lets you refresh brittle plugs or build a new loom with factory‑grade fit and retention.

Why You’ll Want It

• Swap‑friendly: Perfect for custom M57 conversions and standalone looms.
• Reliable signal & sealing: Positive terminal lock and weather seals for stable injector control.
• Serviceable: Replace damaged or broken plugs without changing the whole harness.

What’s Included

• Injector plug housing (OEM‑style)
• Terminals/pins (crimp type)
• Wire seals and rear boot (where applicable)

Compatibility

For BMW M57 diesel engines (all common swap generations). Note that M57 variants use different injector types (early solenoid vs. later piezo). Please specify your injector type/engine code at checkout so we supply the correct connector set for your application.

Installation Notes

• Use a quality open‑barrel crimp tool sized for the supplied terminals.
• Observe pin polarity and harness routing; heat‑shrink recommended for strain relief.
• Dielectric grease on seals can aid assembly and long‑term corrosion resistance.

Use Cases

• M57 engine swap harness builds (4x4, drift, expedition, track)
• Repairing heat‑aged or cracked injector plugs
• Converting/shortening/lengthening injector sub‑looms
