– NGK IMR9E-9HES — Iridium IX fine-wire performance spark plug

Always confirm the NGK reference matches the plug specified in the owner’s manual or service manual before fitting. NGK Iridium IX plugs upgrade a standard plug to a fine-wire iridium centre electrode that fires more reliably across a wider operating range. A common upgrade for sport and performance applications and any engine where the extra cost is justified by the longer service life.
