Our take on the Champion Auto Parts Iridium Champion Spark Plug 9402

The Champion 9402 is an iridium-tipped spark plug sold as a Ford-fitment replacement. Iridium center electrodes last longer than copper or platinum plugs and hold a stable gap, so it suits drivers who want a long service interval without pulling plugs often. It is a single plug, not a set, so a full engine job needs several. Compared with OEM-style platinum plugs it trades a higher part cost for longer life and steadier idle in worn engines.

Questions and answers

Is this plug a direct replacement for my Ford?
It is listed for Ford cars, but fitment depends on engine and year. Check the plug number your owner's manual or under-hood label specifies before ordering.
How many plugs do I need?
One order is a single plug. A four-cylinder engine needs four, a V6 needs six, and a V8 needs eight.
Do I need to gap it before installing?
Iridium plugs usually come pre-gapped. Check the gap against your engine spec and adjust only with a proper gapping tool, since the fine tip bends easily.
How long do iridium plugs last?
Typically far longer than copper plugs, often around 60,000 to 100,000 miles depending on engine and driving. Follow the interval in your Ford's maintenance schedule.
Can I mix this with other plug types?
No. Use the same plug in every cylinder. Mixing heat ranges or materials can cause uneven running and misfires.
Is it worth it over a standard plug?
If your engine is hard to access or you keep the car long, the longer life pays off in fewer replacements. On an easy-to-service engine, a stock plug is fine.
