link hidden, please login to view in a synchronized firing order. The timing is critical to optimize the power created from the explosion or spark. Spark plugs use precisely crafted ceramic insular bodies and punched steel casings, which house two electrodes with a gap in between them. When voltage is sent to the plug, an electrical arc is formed between the two electrodes, thus igniting the fuel/air mixture. Spark plugs determine the power output, fuel economy and even engine temperature of your automobile. Signs that it is time for spark plug and coil replacement include jittery or rough idling, power surges from the engine, diminished acceleration and decreased gas mileage. Remember that spark plugs are not designed to last the lifetime of a vehicle. Built-up deposits and natural widening of the electrode gap can cause spark plugs to fail as time passes, so replacing spark plugs is a routine part of vehicle maintenance. Note: It is always best to replace all the spark plugs at the same time.

With a modern vehicle, you only need to change spark plugs every 100,000 miles thanks to advances in materials and ignition design. Replacing spark plugs will take roughly an hour if your vehicle has a four-cylinder engine. Spark plug replacement takes longer for vehicles with a V6 or V8 engine. A standard vehicle typically has the same number of spark plugs as the number of cylinders. So, a V6 would need six replacement spark plugs. There are exceptions like Chrysler V8s, which use two plugs per cylinder. Which Plug Sparks Your Interest? link hidden, please login to view
At the heart of each spark plug is an electrode that connects to the vehicle’s ignition coil via a thick wire. Spark plugs installed by car manufacturers often contain copper, nickel or chromium core electrodes.

Announced late last year, the name change will include a new corporate logo and identity as the organization follows a strategy to unify the global brand and promote efforts to transform the organization’s business portfolio. Accordingly, the global brand NGK Spark Plug Co. LTD will also begin operating under the English tradename Niterra Co., Ltd on April 1.
“It is an exciting time in the long and storied history of NGK Spark Plug., LTD,” said Michael Schwab, president, and CEO. “We are becoming an increasingly progressive corporation as we strive to meet our vision for the future. A future where we expand our core ceramic technologies, explore capabilities beyond our traditional areas, and challenge ourselves to develop solutions and services that use technologies to resolve social issues while contributing to a sustainable society.”
Niterra, a coined word, combines the Latin words Niteo, meaning shine, and Terra, meaning planet earth. The corporation chose the new name, logo and colors represented to present a broader image of its modern identity.
The company will continue to use the trusted NGK and NTK brands for its spark plug and ceramic-related product portfolio.

Whenever somebody asks me what’s new, I usually respond by saying, “Nothing really.” And that’s the same response I get when I ask the question of others. Why, I’m not sure, because there’s almost always something new. But in my case, it’s probably because it’s not exciting enough to talk about.
So, when I got the question “what’s new with spark plugs?” I knew my standard answer wouldn’t fly. Then I thought: It’s a fair question. What IS new with spark plugs? They do what they do, right? Is it possible for them to change? Copper, platinum or iridium are the main choices we have, and heat ranges differ between applications. But aside from that, have they changed much at all since they were invented?
The answer to that question is yes, and it makes the whole topic a little more interesting. With all the advancements the internal combustion engine has seen over the years, spark plugs are the components that always have had to bridge the gap (no pun intended) between the old and new, and advancements can be tracked throughout the entire existence of the automobile.
Did you know that early spark plugs could be taken apart for cleaning, and that you could buy replacement porcelain insulators and electrodes to effectively rebuild the spark plug? And that they sealed in the cylinder head by pipe threads and the plug wires were held on by a screw?
Here’s another interesting fact: Have you heard of primer plugs? In the early days of the automobile, fuel systems left a lot to be desired with the use of updraft carburetors, and it was often difficult to start a car on cold days due to the lack of fuel getting to the cylinders. Primer plugs had a small cup attached, in which you would put a few drops of gasoline, then open the valve to allow it to flow into the cylinder. The engine then would have fuel to ignite for starting.
We haven’t seen plugs like that in years, and at a glance, today’s plugs look like those from 50 years ago. However, the reality is that they’ve remained in constant evolution. Copper plugs were the standard up through the 1970s, but the need for reduced emissions and leaner-running engines required a stronger spark. The advancements of electronic ignition provided this change, and spark plug technology kept pace with the introduction of platinum precious-metal plugs.
Not too long after, with the introduction of distributorless ignition, the continued development of precious metals led to double-platinum and iridium plugs, as well as fine-wire iridium, allowing precise ignition control and design to maximize combustion efficiency.
Now as we roll through the first part of the 21st century, engineering never slows down for the internal combustion engine, and four valves per cylinder along with direct injection are squeezing the real estate in an engine – and spark plugs have had to get smaller and smaller to fit. This also has opened additional upsell opportunities for tools because the once combination of 13/16-inch and 5/8-inch spark plug sockets that covered every vehicle made is no longer the case. Now we frequently need 9/16-inch and 14-millimeter sockets as well as 12-point variations.
In the world of high performance, smaller plugs are lighter weight and provide room for larger valves, and the smaller hole in the cylinder head provides increased cylinder-head strength as well as improvements in cooling-passage design.
Smaller plugs also mean smaller ceramic insulators, which in turn means engineering improvements to design these smaller insulators so they can retain their high dielectric strength.
Just when you thought there couldn’t be any more advancements, a new precious metal stepped into the game: ruthenium. My first thought was whowhatenium? But I checked: It’s on the periodic table. I must not have paid enough attention in science class. The bottom line is that ruthenium is an incredibly tough and durable metal. When used as the center-electrode material in spark plugs, it offers increased durability and is more resistant to corrosion and oxidation than iridium or platinum.
Ruthenium plugs also have brought new electrode designs in a double fine electrode that maximizes ignitability, designed for normally aspirated engines, and a projected square platinum electrode that provides the best ignitability, designed for turbocharged and supercharged applications.
Ruthenium plugs are generally known for improved cold starting and fuel efficiency, but reportedly don’t perform as well under extreme conditions such as high-speed engine operation or in vehicles hauling heavy loads. They can be a great upgrade for most applications, but be aware of the situations in which they may not perform as well. So, it turns out there IS something new with spark plugs, and at the rate of today’s technology, there most likely always will be.
