Bosch Iridium Spark Plugs Review

Iridium is a precious metal that's 6 times harder and 8 times stronger than platinum and conducts electricity much better. This makes it ideal for a fine wire center electrode in a performance or ultra long life spark plug. The tip of the spark plug is exposed to high temperatures in the combustion chamber. It's a balancing act, the spark plug has to get hot enough to ignite the fuel mixture but it also needs to avoid getting too hot because that can pre-ignite it which destroys your engine.

This plug has an ultra fine wire design and laser welded tapered ground electrode which gives it optimum performance and longevity. It's a good choice for drivers who want to upgrade from basic copper spark plugs that wear out quickly.

All Bosch OE spark plugs are factory pre-gapped so you can be confident they're ready to install and work right away. They have a patented technology which allows them to perform at a higher level, improve the reliability of your ignition system and help you save on gasoline.

Spark plugs are one of the most important parts in your car's ignition system. They are the only point of contact between your car's engine and the air it needs to run. Unfortunately, they're often overlooked by drivers and can cause major problems like hard starting, misfires and poor gas mileage. This is why it's always a good idea to replace your spark plugs regularly with the recommended model from your vehicle's manufacturer.
