Spark plugs light the fuel mixture in an engine, providing the power to drive your vehicle. It gets a spark from the electronic ignition system in today’s vehicles or the distributor cap and rotor in vintage automobiles.
Eventually, at 30,000 miles or more, traditional spark plugs will wear out causing stalling, starting difficulties, and engine misfires. Platinum-tipped spark plugs with a higher cost may not need to be replaced as often. At the same time, your oxygen sensor, spark plug wires, PCV valve, and fuel filter could all require replacement.
The spark plugs are a major part of your car’s ignition system. They ignite the gasoline and air within your engine. This gives your vehicle the power to get you from point A to B.
The spark plug generates a spark at the precise time in the engine’s combustion cycle, thanks to high voltage electricity from the ignition coil. This delivers optimum power, fuel efficiency, and low emissions for the engine. The electrode at the tip of the spark plug, on the other hand, wears down with time and can result in performance difficulties.

GM’s oldest brand, which has been selling big, bodacious Buick sedans, coupes, convertibles, and wagons for the last several years, now enters 2021 with an all-SUV lineup. The assortment of sport utilities at the Buick dealership is among the most modern in the industry, with an all-new second-generation 2021 Envision adding to its appeal.
The Envision is Buick’s only vehicle to come from China, a market that purchases twice as many Buicks as the United States. It’s likely that the legendary brand would not have survived GM’s bankruptcy in 2009 if there was no strong demand for Buicks in China.
The Envision is rechristened for 2021 as a sportier, more premium near-luxury compact SUV. Except for the Buick badge, the new Envision has a sloping roof, shorter overhangs, and overall proportions that one might associate with an Audi or Mercedes-Benz. With a longer wheelbase for greater rear-seat passenger space and a more contemporary appearance than before, the new Envision continues to promote quiet comfort but in a more modern style.
The 5-seat Envision is available in Preferred, Essence, and Avenir trim levels.
What are the different types of spark plugs?
Keep in mind that you can’t just swap any spark plug into any engine. Check with your Owner’s Manual to see what it says and stick to it!
Copper Spark Plugs: The most basic spark plugs, known as “simple” spark plugs, are nickel-coated and copper-based. Copper is a good conductor, and it has the lowest price of all the materials tested; nevertheless, they tend not to survive as long.
Platinum Spark Plugs: Platinum is more heat-resistant than copper (and inhibits deposit formation). Platinum-tipped earplugs tend to survive longer than copper ones.
Double Platinum Spark Plugs: are not twice as good as platinum spark plugs, but in this case, the spark plugs include platinum on two electrodes: the center electrode and the ground electrode.
Iridium Spark Plugs: Platinum is more difficult and durable than iridium. (It’s also more expensive!) The electrode is thinner because of the cost of iridium, but they still deliver greater power, combustion, and life than other plugs.
