About the product

The NGK SILMAR8A9S 90992 is a spark plug in the NGK Laser Iridium range, with a 10 mm diameter.

It has a laser-welded iridium centre electrode and a platinum pad on the ground electrode. Both wearing surfaces are precious metal. The plug is original-equipment specification and can be used as a like-for-like replacement where the vehicle handbook specifies this part number. Consistent ignition over the plug's life keeps fuel consumption and emissions where the manufacturer intended.
