The NGK ILZKAR8J8SY (NGK 95660, Honda 12290-5PA-A01) is an OE-spec iridium spark plug for Honda and Acura 1.5T and 2.0T engines. It uses a laser-welded iridium center electrode and a fine-wire platinum ground electrode for a small tip diameter, which NGK says gives strong ignitability, stable idle and slow wear. It comes pre-gapped at 0.030 inch, the factory spec, and is sold as a single plug. It suits owners doing scheduled maintenance or replacing plugs on tuned turbo cars; it is a direct-fit OE part rather than a performance upgrade, and the main choice is buying the exact heat range your engine calls for.

Owners of 1.5T and 2.0T Hondas and Acuras treat these as the correct stock replacement, reporting smooth idle and clean running after fitting. Complaints center on buying them one at a time and on checking the gap before install.
The NGK Laser Iridium ILZKAR8J8SY is a single spark plug and a direct replacement for the original equipment plug. It has a laser-welded iridium center electrode tip. A platinum disc is welded to the back of the ground electrode.
The fine wire center and ground electrodes give the smallest tip diameter available with iridium and platinum surfaces. These surfaces wear slowly, give a stable idle and resist fouling. The plug is designed to improve fuel efficiency, lower emissions, and give faster starts and quicker acceleration.
Trivalent Metal Plating protects against corrosion and seizing. The plug comes pre-gapped at the factory spec of 0.030". Double-check the gap before installing. Gapping and indexing are recommended for high boost and high power engines.
