Features: Sold as a set of 4. The trivalent metal plating offers excellent anti - corrosion and anti - seizing. Corrugated ribs stop flashover. The pure alumina silicate ceramic insulator provides great strength and good heat transfer. With a 0.4mm Ruthenium alloy fine - wire center electrode and 0.8mm platinum fine - wire ground electrode, it enhances performance. The copper core helps remove heat. It has a longevity of 60 - 120k Miles and comes with a 60 - day manufacturer warranty. Shell Details: Spark Plug Thread Diameter is 14mm, Thread Pitch is 1.25mm, Seat Type is Flat, Reach is 26.5mm (1.04'), Wrench Diameter is 5/8' (16mm), Terminal Type is Solid, and Gap is.031' (0.8mm). Center Electrode: The tip is made of Ruthenium and the core is copper. Ground Electrode: It's made of copper, with a standard type and taper - cut shape. Specifications: It has a 5k Ohm resistor, manufacturer heat range is 6, and torque specs are 18 - 25.3 lb. ft. for cast iron and 18 - 21.6 lb. ft. for aluminum. The NGK Ruthenium HX is perfect for newer engines needing high ignitability. Its Double Fine Electrode (DFE) design focuses spark energy and ignites different air - fuel ratios, improving performance in various engine conditions.

Using these NGK spark plugs is straightforward. First, make sure your engine is cool before starting the replacement process. Refer to your vehicle's manual to locate the spark plugs. Use a proper spark plug socket to remove the old ones and carefully install the new NGK Ruthenium HX spark plugs. Make sure to tighten them according to the torque specs - 18 - 25.3 lb. ft. for cast iron engines and 18 - 21.6 lb. ft. for aluminum engines. As for maintenance, it's a good idea to check the spark plugs periodically, especially after every 30k miles. Look for any signs of corrosion or damage. The trivalent metal plating on these spark plugs provides anti - corrosion properties, but if you notice excessive wear, it might be time to replace them. Keep in mind that these spark plugs are designed for specific Subaru models, so don't use them on other vehicles unless you've confirmed compatibility. Also, store the spark plugs in a dry place to avoid any damage. If you have any issues, the 60 - day manufacturer warranty has you covered, so contact us right away.
