Does this plug fit my car?

Check your engine against the listed applications. It covers many Chrysler 300, Dodge Charger, Challenger, Durango and Ram models plus Hyundai Santa Fe, Sonata, Tucson and several Kia models from about 2008 to 2013. Confirm by engine and year before buying.

How often should iridium plugs be replaced?

Iridium plugs typically last far longer than copper plugs, often around 60,000 to 100,000 miles depending on the engine. Follow your owner's manual interval for the specific vehicle.

Do I need to gap it before installing?

Check the gap against your vehicle's spec before fitting. Plugs can shift in shipping, and iridium tips are fragile, so use a gap tool carefully and avoid bending the center electrode.

Is it better than a copper or platinum plug?

For the listed engines it offers longer wear life and steadier spark than copper. Platinum is a middle option; iridium generally lasts longest but costs more.

How many plugs do I need?

One plug per cylinder. Most listed four-cylinder engines need four and V6 or V8 engines need six or eight, so order the full set for a complete tune-up.
