A-Premium Ignition Coil Pack and Iridium Spark Plug Kit – Set of 4 for Nissan/Infiniti, Bolt-On OEM Fit, Pre-Gapped

The A-Premium set of four ignition coil packs and iridium spark plugs is a complete replacement kit engineered to restore consistent ignition performance for compatible Nissan and Infiniti models.

This kit bundles four bolt-on ignition coils with four iridium-tipped spark plugs, matched and pre-gapped for many Nissan and Infiniti engines.
