The BTR Fuel Injector Connector with Pigtail (4 Pack) is engineered as a premium, direct replacement for the factory injector connectors on 2017–2025 Chevy and GMC 6.6L L5P Duramax engines. Over time, the original connectors are prone to increased resistance and corrosion, which can trigger injector-related DTCs (P0201–P0208) and lead to misfires or poor engine performance.
Each connector is built from high-temperature, automotive-grade materials to withstand the harsh conditions of the engine bay and deliver long-lasting reliability. Designed for a precise fit, these connectors restore proper electrical connection to your fuel injectors and help resolve common drivability issues.
