Overview

The COBB Tuning SILKFR8A6 spark plug is a direct-replacement, OEM part for select Subaru vehicles.
Show original supplier description
This design promotes a stable idle, improved anti-fouling capabilities, enhanced fuel efficiency, and reduced emissions. Constructed with a pure alumina silicate ceramic insulator for superior strength and heat transfer, and a copper core for efficient heat removal, these spark plugs also incorporate corrugated ribs to prevent flashover and triple seals to prevent leakage. The trivalent metal plating offers enhanced anti-corrosion and anti-seizing properties, ensuring durability and ease of installation. This spark plug is specifically designed as the stock-replacement for the 2022-2023 Subaru WRX with the 2.4L FA24 engine. It is also listed as fitting the Subaru Ascent, Legacy, and Outback models, though specific year ranges for those vehicles are not detailed in the provided evidence.
