When Ignition Coils and Spark Plugs May Need Service

Ignition coils and spark plugs may need inspection when the engine has rough idle, hard start, hesitation, poor acceleration, poor fuel economy, or a check engine light. These symptoms can also be caused by fuel delivery, vacuum leaks, wiring, sensors, or engine mechanical faults. If you are comparing symptoms and repair cost, review ignition coil replacement cost before ordering parts.

UF407 and 2382 Reference Checks

Compare UF407, GN10301, IC527, C-637, and C1340 with the original coil.
Compare spark plug references 2382 and BKR5ES-11 with the required plug specification.
Confirm that 2 ignition coils and 4 iridium spark plugs match the repair quantity.

For a broader explanation of how ignition coils and spark plugs work together, read the ignition coil vs spark plug guide. This BDFHYK set is an OE-style aftermarket replacement, not a factory-branded Mazda part.

Q: Will this UF407 ignition coil and spark plug set fit my Mazda Protege?
