Buying Guide

When it comes to choosing the best spark plug for your vehicle, there are a few key features to consider. Here are some factors to keep in mind:

Heat Range

The heat range of a spark plug refers to its ability to dissipate heat. It’s important to choose a spark plug with the correct heat range for your engine, as a plug that’s too hot or too cold can cause problems such as pre-ignition or fouling. Consult your vehicle’s owner’s manual or a trusted mechanic to determine the appropriate heat range for your engine.

Material

Spark plugs can be made from a variety of materials, including copper, platinum, and iridium. Each material has its own advantages and disadvantages in terms of performance and durability. For example, copper plugs are inexpensive but have a shorter lifespan, while iridium plugs are more expensive but offer better performance and longevity. Consider your budget and driving habits when choosing a spark plug material.

Gap Size

The gap size of a spark plug refers to the distance between the center and ground electrode. The gap size can affect the performance of your engine, so it’s important to choose a spark plug with the correct gap size for your vehicle. Again, consult your owner’s manual or mechanic for guidance.

Brand

While we won’t recommend any specific brands, it’s important to choose a reputable manufacturer when purchasing spark plugs. Stick to well-known brands with a proven track record of quality and reliability.

By considering these factors, you can choose the best spark plug for your vehicle and ensure optimal engine performance.
