914Rubber Four Pole Fuel Injector Boot for 914 for D-Jetronic Fuel Injection
Enhance your Porsche 914’s D-Jetronic fuel injection system with the 914Rubber Four Pole Fuel Injector Boot (part number 311.906.102.C), designed for 914 models from 1970-76 with 1.7L or 2.0L engines. This reproduction rubber boot protects the four-pole injector connector, shielding it from heat, moisture, and engine bay debris. A degraded boot can cause electrical faults, leading to misfires or inconsistent fuel delivery, but this durable 914Rubber boot ensures a stable connection for optimal injector performance. Only one is required per car.
With over 20 years of Porsche 914 expertise, PMB Performance has partnered with 914Rubber for nearly two decades, selling more 914Rubber SKUs than any other retailer. This boot is molded from high-grade, heat-resistant rubber, capable of withstanding temperatures up to 220°F and resisting fuel vapors that degrade lesser materials. It fits securely over the four-pin connector, maintaining signal integrity for the injector’s 2.5-ohm coil, which is critical for the D-Jetronic’s precise pulse-width control.
The four-pole injector, used in specific D-Jetronic setups, often supports auxiliary functions like fuel enrichment under load. A compromised boot risks corrosion or signal disruption, which can throw off the ECU’s air-fuel calculations, causing rough running or poor throttle response. This 914Rubber boot restores reliability with a weather-tight seal, preventing arcing and extending injector life. Installation requires care to ensure proper seating without stretching.
