Fitment varies by engine, not just by make and model. Cross-check the Champion 7304 part number against your owner's manual or the plug currently in the engine before ordering.

Are double platinum plugs better than iridium?

Iridium tips last longer in many applications, but double platinum is the better match for waste-spark ignition because both electrodes wear. Use what the manufacturer specifies.

Do I need to gap them?

They come preset, but check the gap with a feeler gauge before installing. Adjust carefully to avoid damaging the platinum pad.

How often should they be changed?

Follow the interval in your owner's manual, often around 60,000 to 100,000 miles for platinum plugs. Severe driving shortens that.

Ten individually boxed Champion 7304 spark plugs. No tools or gap gauge are included.

Can I use them in a turbo or high-performance engine?

Only if the manufacturer calls for this plug and heat range. Modified or boosted engines usually need a colder plug and a different gap.

Our take on the Champion 7304 Double Platinum Spark Plugs 10-Pack

The Champion 7304 is a double platinum spark plug with platinum pads on both the center and ground electrodes, which slows gap erosion and stretches service life compared with single-platinum and copper plugs. It is a standard-reach plug aimed at late-model cars and trucks with waste-spark or distributorless ignition, where the plug fires from both electrodes. It is a mainstream replacement rather than a performance plug, so it trades exotic materials like iridium for durability at a lower cost per plug. The 10-pack suits V8 and V6 owners doing a full set with spares, or shops stocking a common fitment.

Pros

Platinum on both electrodes resists gap growth over a long service life
Fires reliably in waste-spark systems that reverse polarity each cycle
Copper core conducts heat well and resists fouling
10-pack covers a V8 set with spares for a V6
Widely available cross-reference to common OEM plug numbers

Cons

Not iridium, so it won't outlast premium plugs in hard service
Gap is preset but should be checked before install
Counterfeit plugs circulate online, so buy from a trusted seller
No performance gain over a standard plug in a stock engine
