Set of 4 Nippon Denso fuel injector connector with 6.20 inch pigtail wires. We only use the best quality Pigtail wires - GXL automotive wire with Cross-Linked Polyethylene (XLPE) insulation material (SAE Spec J-1128, meets or exceeds Ford Spec M1L-123A, Chrysler Spec MS-8288 and Delphi spec). Conductor material is 100% copper. Beware of other vendors selling these connectors with non-automotive grade PVC insulated wire – this type of wire does not belong in an engine compartment of a modern automobile. Inferior PVC insulated wire does not have anywhere near the thermal, oil and solvent resistance of Cross-Linked Polyethylene (XLPE) insulated wire. If you hold a PVC insulated wire to the flame of a lighter for a few seconds it will quickly melt and burn leaving a charred black brittle residue. XLPE insulated wire will easily withstand this flame test and retain its insulating properties and flexibility. These connectors will work with a large number of Japanese applications such as Toyota, Mazda, Honda, Nissan, Subaru, etc.Will fit all Denso injectors. This is a top slot connector.
