Choosing Spark Plugs for Your Car

Choosing the right spark plugs for your car can greatly improve its performance and fuel efficiency.

You’ll want to start by checking your vehicle’s owner manual to find the recommended spark plug type and gap size.

Consider the material: copper plugs offer good conductivity but wear out faster, while platinum and iridium plugs last longer and provide better ignition.

Also, think about your driving habits; if you often drive in tough conditions or want a smoother idle, premium plugs might be worth the investment.

Don’t forget to match the heat range to your engine’s requirements, as using the wrong one can cause fouling or overheating.
