Product Description

The NGK 93528 (ILMAR8G8GS) is a Laser Iridium spark plug from NGK's premium ignition lineup, built around a fine-wire iridium center electrode paired with a fine-wire platinum ground electrode. This dual precious-metal construction is designed to deliver a slow wear rate, a stable idle, and strong resistance to fouling over the plug's service life, while supporting improved fuel efficiency and lower emissions.

Trivalent metal plating on the shell adds anti-corrosion and anti-seizing protection, which helps keep the plug easier to install and remove even after extended time in the cylinder head. As with NGK's broader Laser Iridium range, the fine-wire electrode design is intended to deliver stronger spark energy than a standard nickel plug without the added cost of a full precious-metal plug across both electrodes.

Since no vehicle application or detailed dimensional specification was available for this specific stock number from the sources checked, the safest way to confirm this is the right plug for your engine is to cross-reference the ILMAR8G8GS service number directly against your OE spark plug part number, or contact NGK/a retailer's fitment tool to verify compatibility before ordering.
