Product Description

The NGK 92725 (SILZKFR8H7S) is an OEM-grade Laser Iridium High Ignitability spark plug covering a wide range of turbocharged European and Japanese platforms, including Mercedes-Benz M260/M274, BMW B46/B48/B58, Infiniti MR20DD, and the Toyota GR Supra A90's shared BMW B58 engine. Plug quantity per vehicle varies: 4-cylinder engines require 4 plugs; inline-six engines require 6. This plug is a direct OEM replacement for Mercedes-Benz part number 2701590700, requiring no modifications to install.

Featuring NGK's Projected Square Platinum Electrode (PSPE) design paired with an iridium center electrode, this plug delivers maximum ignitability for both turbocharged four-cylinder and six-cylinder applications. Buyers should confirm their specific engine code before purchasing, as AMG performance variants and plug-in hybrid sub-models may use different plug specifications. The tight pre-set gap of 0.028" is specific to these high-compression modern turbocharged engines.
