Premium Iridium Ignition Plug for Honda Engines
This iridium fineโwire plug is built for precise ignition in modern Honda gasoline engines. It delivers a strong spark, fast cold starts, smooth idle, and improved fuel economy. Heat range and reach match OEM specs, making it a direct, reliable fit for daily driving and spirited runs alike. โ๏ธ
Why you need it
Fresh plugs restore lost power, cut fuel use, and keep the catalytic converter safe. Iridium lasts longer than copper or platinum, holding gap and firing clean under load and high RPM.
How it works โก
A fine iridium center electrode and a ground strap create a focused spark across a set gap. The ceramic insulator controls heat, the resistor reduces radio noise, and the plated shell seals combustion gases. The result: consistent ignition of the airโfuel mix in every cylinder.
If worn or broken โฝ
Expect hard starts, misfires, rough idle, sluggish acceleration, higher fuel burn, and potential catalyst damage. A flashing MIL under load means stop and diagnose before harm spreads.
Install tips ๏ธ
Fit on a cold engine; gap is factoryโset for this applicationโavoid prying the fine tip. Do not overโtighten; torque to spec. Use dielectric grease in the boot. Replace as a set around 100,000 km or sooner in harsh use.
