Product Details

NGK brings more OE ignition expertise globally than any other brand, backed by more than 80 years of automotive experience. The 58984 boot is part of NGK’s ignition product range, which includes spark plugs, glow plugs, ignition coils, coil-on-plug boots, and wire sets. For drivers and technicians servicing GM-based V6 engines, this boot supports direct ignition coil-to-spark plug connection on vehicles such as the Cadillac CTS, Chevrolet Impala, and GMC Acadia when the listed fitment matches the application.

This part cross-references DENSO Auto Parts 671-6307 and Standard Ignition SPP142E for the same application.

What It Helps Address
