BDFHYK UF603 Ignition Coils Set of 6 with Iridium Plugs

BDFHYK offers a combined ignition coil and iridium spark plug kit designed to restore smooth starts and steady power in V6 Honda and Acura models. These coil packs pair durable materials with iridium-tipped plugs to tackle misfires, long cranks, and reduced fuel efficiency that show up after high mileage. If your vehicle shows rough idle or sluggish acceleration, this set aims to recover responsiveness and more consistent combustion.

Key features

The kit brings together ignition coils made with Japan-imported rubber and Germany-imported varnished wire, built to resist heat and vibration. Spark plugs use iridium electrodes and hydrostatic ceramics, hot riveted for reliable spark delivery and longer life. Manufacturer references include OE numbers such as 30520-RN0-A01 and 97390, helping confirm fitment for many Honda and Acura V6 engines. Note that compatibility depends on model year and OE cross reference, so check those details before purchasing.

Usage tips

It makes sense if you replace ignition components after extensive mileage, especially when you notice harder starting and higher fuel use. Install one bank at a time if you want to test improvement before swapping all six coils and plugs. Keep in mind that fitment varies by model year, so verify OE numbers and engine size.

Care & maintenance

Routine inspection of ignition components helps maintain peak engine performance, according to common maintenance practice. When replacing plugs and coils, use proper torque specs and follow recommended service intervals, and discard damaged wires or connectors to avoid recurring faults.
