If you're looking for the best spark plug for your car, you may be wondering if NGK iridium or platinum is the way to go. Here's a look at the pros and cons of each type of spark plug to help you make the best decision for your vehicle.
NGK iridium spark plugs are made with a fine-wire electrode that helps provide better durability and a more focused ignition than standard copper plugs. These plugs also tend to last longer than copper or even platinum plugs, so they may be a good choice if you're looking for extended wear. However, they can be more expensive than other types of plugs.
Platinum spark plugs have a flat electrode that helps improve ignitability and fuel efficiency. They also offer long wear life, although not as long as NGK iridium plugs. Platinum plugs can also be more expensive than copper or standard nickel alloy plugs.
