These spark plugs fit a wide range of Subaru models, including the 2004 - 2006 Baja, 2004 - 2013 Forester, 2004 - 2014 Impreza, 2005 - 2019 Legacy, 2005 - 2019 Outback, 2013 - 2014 WRX, and 2013 - 2018 WRX STI. The trivalent metal plating offers excellent anti - corrosion and anti - seizing protection. Corrugated ribs prevent flashover, ensuring a stable spark. The pure alumina silicate ceramic insulator provides great strength and efficient heat transfer. With a 0.4mm Ruthenium alloy fine - wire center electrode and 0.8mm platinum fine - wire ground electrode, it can ignite a wide range of air - fuel ratios. The copper core helps remove heat effectively. These spark plugs have a long lifespan of 60 - 120k miles and come with a 60 - day manufacturer warranty. The spark plug has a 14mm thread diameter, 1.25mm thread pitch, flat seat type, 26.5mm reach, 5/8' (16mm) wrench diameter, solid terminal type, and a 0.031' (0.8mm) gap. The center electrode is made of Ruthenium with a copper core, and the ground electrode is copper, standard type, and taper - cut. It also has a 5k Ohm resistor and a manufacturer heat range of 6. Torque specs are 18 - 25.3 lb. ft. for cast iron and 18 - 21.6 lb. ft. for aluminum. NGK Ruthenium HX is perfect for newer engines that need high ignitability. Import Image Racing is an authorized NGK dealer, so you're guaranteed authentic products and manufacturer warranty.
Using these NGK spark plugs is straightforward. First, make sure your engine is cool before starting the replacement. Remove the old spark plugs carefully using a suitable spark plug socket. Then, install the new NGK LFR6BHX Ruthenium HX spark plugs, tightening them according to the torque specs - 18 - 25.3 lb. ft. for cast iron engines and 18 - 21.6 lb. ft. for aluminum engines. When handling the spark plugs, be gentle to avoid damaging the electrodes. For maintenance, check the spark plugs periodically, especially if you notice a decrease in engine performance. These spark plugs are designed to last 60 - 120k miles, but regular inspection can help you catch any issues early. If you see excessive corrosion or damage, it might be time to replace them. Keep them in a dry place when not in use to prevent corrosion. And remember, since you bought from an authorized dealer, you have a 60 - day manufacturer warranty, so if there are any problems, you're covered.
