Does it matter what brand spark plugs you use?

In other words, any brand of spark plug can be used in any vehicle make or model application assuming the plug has the correct dimensions, design and heat range. The engine won't know the difference.

Do expensive spark plugs make a difference?

The most expensive type of spark plug is the iridium type. It is harder and more durable and generally lasts longer than platinum types. They have a smaller center electrode and fine wire centers which can generate current faster. It provides better power and complete combustion that leads to better engine performance.

What type of spark plugs last the longest?

Long-life platinum and iridium spark plugs will typically last up to 100,000 miles or longer provided the engine isn't using oil or doesn't spend a lot of time idling. Replacing spark plugs at 100,000 miles can be troublesome on some applications.

Which is better Bosch or NGK spark plugs?

There is no doubt that NGK spark plugs are great, yet Bosch ones also work decently at ignitability and combustion. The real difference lies in thermal transfer between electrodes and engine cylinders. Also, the double-electrode technology and durable materials are other advantages.

Keeping combustion gasses where they belong (i.e., in the cylinders) is a triple-layer gasket. The anti-corrosion trivalent metal plating on the body and threads of these iridium plugs reduces the likelihood of them getting stuck in a vehicle's cylinder head, even after many years of hard service. As for customer ratings, this iridium spark plug has earned 4.7 stars out of five after nearly 1,300 reviews.

How to use a spark plug gauge?

Easier to use than a ramp-style gapping tool , feeler gauges give you a precise spark-plug gap every time. If your vehicle manufacturer specifies a gap of 35-thousandths of an inch (0.035), then just fan out a 15-thousandths and a 20-thousandths feeler and you're good to go. If the gap is too wide, just tap the spark plug on a flat surface to close it up so the feelers have some drag. If it's too tight, bend it to open it more. Feeler gauges can also be used in other applications beyond just setting spark-plug gaps.

Do spark plugs have multiple electrodes?

When shopping for new spark plugs, it's best to steer clear of ones that have multiple electrodes.
