An ordinary car enthusiast, when it is time to change the candles, goes to the car dealership and buys those that are installed on his car according to the catalog. It is rare when the question arises which spark plugs are better, because the main selection criterion is the price of the product. Moreover, as a rule, the original candles supplied by the car manufacturer are much more expensive than the counterparts from other companies specializing in the production of candles. But the quality of cheap candles is usually lower than that of the original product. Thus, it all depends on the client’s availability of money - if there is not enough money, we select analogues, if they are in abundance, we choose the option from the car manufacturer.
But if you are the owner of a tuned car, or want to get a little more from your car than standard spare parts can offer, then you need special candles, and the question of which spark plugs to choose for you is not idle. Since their choice in relation to the above area of use is quite large.
The main goal of those auto parts suppliers that specialize in candles for demanding customers is to provide consumers with a product that will be favorably different from standard designs. And all the efforts of specialized companies, among which the most famous are Bosch, SplitFire, Champion and several others, are aimed precisely at ensuring these differences. Let's try to figure out which of the presented manufacturers produces spark plugs, which are better and which are worse.
So, Bosch offers auto enthusiasts its SUPER 4 candles, which instead of one standard electrode have as many as four. The company claims that such a solution allows the spark to choose the best option out of as many as eight possible travel routes. But experts point out that there is still no clear answer to the question of which spark plugs are better, with one electrode or several. The opinions of specialists on this issue differ significantly from the Bosch triumphant reports. Some of them believe that a large number of electrodes prevents the normal penetration of the mixture into the point of passage of the spark and reduces the efficiency of the engine. The only plus of this solution is durability, when one electrode becomes dirty or loses its shape, the spark jumps to another.
The answer to the same question, which spark plugs are better, according to SplitFire, sounds something like this: with a standard central electrode, a spark ignites the mixture worse, since its bent end closes the spark. To eliminate this effect, the company offers its candles with a central electrode bifurcated at the end, the shape of which resembles the letter V, and the contact pads are covered with platinum. As the advertising materials say, the patented form with two points along which the discharge can pass allows the mixture to freely enter the channel through which the spark jumps. Which increases the efficiency of the engine and improves its efficiency. It is a pity that the United States Federal Trade Commission disagreed with the company. SplitFire was fined for cheating on ads that promised fuel economy, but in fact this did not happen.
The question of which spark plugs are best never sounds at Champion’s headquarters, as everyone knows the answer well - of course, products from this division of the Federal-Mogul Corporation! This manufacturer has the longest history of all presented in this article; the company has existed since 1908. Back in the seventies of the last century, Champion proposed to use rare earth metals in the production of candles . In its products, the company uses iridium on the central electrode, and on the lower platinum. According to Champion representatives, this, together with a special form of the lower electrode, sharpening towards the end, achieves a “sparking focus”. The quality of the original Champion candles with an iridium-platinum coating is not in doubt, but they have a serious minus. The price of 4 pieces can reach 90-100 dollars, but the mileage on one set can be over 90,000 km.
So, now, after reading this article, you can, armed with information about the technologies used in the design of candles, choose competently.
