COIL ASSY. PLUG TOP

Plug‑Top Ignition Coil for Honda Engines ⚡

Keep your Honda starting quick and running smooth with this plug‑top ignition coil. The coil‑on‑plug design mounts directly on the spark plug, delivering a strong, clean spark exactly when the ECU commands it. Result: fast starts, steady idle, full power, better economy, and lower emissions. 🚗

Why you need it

Heat and vibration age coils. Insulation weakens, resistance rises, and spark energy drops. Replacing a tired unit restores proper combustion, protects the catalytic converter, and prevents misfire damage.

How it works

The ECU switches current through the primary winding. When the field collapses, the secondary winding boosts voltage to 20–40 kV and fires the spark plug right in the cylinder. The molded boot seals the plug well and keeps out moisture and dust. 🔧

What happens if it’s broken

Expect rough idle, hesitation, poor acceleration, higher fuel use, sulfur/raw‑fuel smell, and a Check Engine light (common codes P0300–P0304). Long driving with a weak coil can overheat and damage the catalytic converter.

Pro tips

Install with clean terminals, seat the boot fully, and pair with fresh spark plugs. If one coil failed from age, testing the rest is wise.
