Premium Iridium Ignition Plug for Honda Engines

This iridium fine‑wire 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. ⚙️

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 ⚡

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 air‑fuel mix in every cylinder.

If worn or broken ⛽

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 ️

Fit on a cold engine; gap is factory‑set for this application—avoid prying the fine tip. Do not over‑tighten; torque to spec. Use dielectric grease in the boot. Replace as a set around 100,000 km or sooner in harsh use.
