Product Description

The NGK 96748 (LKAR8AP7JDS) is an OEM-specified Laser Platinum multi-ground spark plug engineered for the Alfa Romeo Giulia and Stelvio equipped with the 2.9L V6 Biturbo engine, including all trim levels from Base to the performance Quadrifoglio. The dual ground electrode design improves ignition consistency and reduces sensitivity to gap wear over time, making it especially well-suited for the high-compression, turbocharged environment of these engines. The laser-welded platinum center electrode delivers a focused, repeatable spark with minimal voltage loss across the service interval.

Backed by NGK's OEM-level manufacturing standards, this plug features a corrugated ceramic insulator to prevent flashover, triple-sealed construction to stop combustion leakage, and trivalent metal plating on the shell for corrosion-free removal at service time. It installs directly in place of the factory plug without modification and is confirmed to match Alfa Romeo OEM part number 68316113AA. Six plugs are required per vehicle. Replacement is recommended every 30,000-50,000 miles depending on engine load and operating conditions.
