The ACDelco NGK TR5IX is a powerful plug for a powerful engine.
NGK spared no expense when making this spark plug. What you get here is a plug with an iridium electrode. It has a fine wire center electrode that provides consistent sparks and reduces fuel consumption.
Spark plugs with Iridium electrodes are of superior quality. Nickel and platinum electrodes can’t compare to it. Iridium is harder, more durable, and more resistant to heat than nickel and platinum. This translates to longer life, better fuel consumption, and more power. Like most spark plugs, it uses a copper core.
It comes pre-gapped for an easy fix. It has a trivalent metal plating that provides corrosion resistance and anti-seizing for quick and easy removal. Its ribbed protection shield eliminates flashovers and misfires.
