6 PACK / PIECES X OEM Quality IGNITION SPARK PLUG. PREMIUM IRIDIUM SPARK PLUG

An internal combustion engine requires three key ingredients: air, fuel, and spark. A spark plug is a critical engine component that provides the spark that ignites the air-fuel mixture that drives an engine.

A spark plug operates by directing electrical current to flow through a center electrode, forming a spark across an electrode (or air) gap, completing the circuit to a ground electrode. The center electrode is surrounded by a non-conductive ceramic insulator that prevents current leakage and ensures electricity flows in the desired direction.

What are the symptoms of a failing crankshaft angle sensor on ignition?

A failing crank angle sensor causes ignition timing to be incorrect or absent, resulting in misfires, hard starting, rough idle, stalling, or a no-start condition. Fault codes P0335-P0338 are commonly associated with this fault.

How often should I replace ignition leads?

Ignition leads typically last 60,000-100,000 km depending on the vehicle and operating conditions. Signs of worn leads include misfires, rough idle, poor fuel economy, and visible cracking or carbon tracking on the lead insulation.

What is the difference between a coil pack and a coil-on-plug ignition coil?

A coil pack serves multiple cylinders from one unit via ignition leads. Coil-on-plug (COP) ignition has one individual coil per cylinder sitting directly on the spark plug. COP systems are more common on modern vehicles and generally provide stronger, more precise spark.

Can a faulty ignition coil damage my catalytic converter?

Yes. A misfiring cylinder caused by a faulty ignition coil sends unburnt fuel into the exhaust, which can overheat and damage the catalytic converter. If you have a misfire fault code, address it promptly to protect your catalytic converter.
