10 best spark plugs from Aliexpress

The spark that the platinum electrode gives out is more stable, and if it is distributed in three directions, then the candle can already be considered a top one. It is this model that is now in front of us, and here an attractive price and a very low price tag are perfectly combined. The candle costs only 135 rubles, including delivery. At the same time, it is platinum and it has 3 side electrodes. Very rare even by AliExpress standards. The product is designed for use in motorcycle engines of various sizes, from 50 to 250cc. The size and form factor allow it to be installed on almost any motor layout on the frame. True, the manufacturer’s marriage is quite common, which is clearly visible if you go to the reviews.

Many of us come to the Aliexpress site in search of savings, since you can buy almost any product in a regular store, but it will usually cost more. If you are here to save your hard-earned money, then here is the cheapest motorcycle spark plug on the platform. Its price tag is only 88 rubles, and this is already taking into account delivery. However, it cannot be called low quality.For example, there are three side electrodes at once, which is not so common in the more expensive segment. Accordingly, the service life will be very high, although the center electrode is nickel, not platinum or iridium. However, nickel models are rare for such an amount.

Motorcycle owners often complain that they are bypassed by top brands. But this is not always the case. Now we have one of the most famous Chinese manufacturers producing the best spark plugs according to many users and professional experts. Despite the fact that a nickel electrode is used here, the model shows a good test result. Finding confirmation of this on the net is very easy, as the brand is popular and in demand. But it also has an important drawback - the price. The candle is expensive. Yes, it is similar to NGK and strictly corresponds to the declared parameters, but for the same money you can find an option in a regular store without resorting to Aliexpress.

A tool that runs on a gasoline internal combustion engine also needs to be replaced sooner or later. Now we have a reliable module with a nickel electrode and a total length of 45 millimeters. Suitable for GX25 and GX35 engines according to Honda classification and, accordingly, engines of similar characteristics. There are no obvious advantages to the candle. It is standard and has a classic set of parameters, but there are a lot of positive comments in the reviews, in which users praise the product for its quality and reliability. An excellent analogue of the original spare part, but at a price several times lower. A lot of praise for the efficient seller, which is also very important for Aliexpress.

Standard spark plug marked D8TC. Suitable for installation in engines from 125 to 250 cubic meters. Designed for motorcycles, scooters and other vehicles. The iridium electrode provides long service life and performance throughout the entire service life. The glow number for this segment is high, that is, the candle will not overheat after prolonged use. But the main advantage is the availability of European certificates. Despite the fact that the brand is sold only on AliExpress, it has all the technical documentation that allows you to use candles as an alternative to the expensive original. All specified parameters are correct.

Before us is a platinum candle with 4 side electrodes. This is the largest number among our participants, and this arrangement allows us to significantly reduce wear on the module and make the spark as stable as possible. The candle is an analogue of NGK Laser Platinum, and the same technology for the production of the central electrode is used here as in the original. Of course, we can only take the word of the manufacturer, but in the reviews of this and other sellers there are many comments regarding good quality and strict compliance with the specified parameters. However, the price here is appropriate. For such parameters, it is quite adequate and you can’t call a cheap candle.

Feedback from real buyers allows you to find the best products on Aliexpress and form your own opinion about their quality and reliability. Unfortunately, not every product receives a sufficient number of comments, and this product can safely be called the most popular.This is a similarly marked Denso spark plug, but the price is much lower than the original, and, apparently, this is the reason for such popularity. There are also comments from people who order these candles not for the first time. They talk about high quality and reliability, which makes them come back to the product again and again.

Iridium plugs allow manufacturers to install the thinnest possible center electrodes. For example, in this design, a diameter of only 0.6 millimeters is used, and this is a very impressive figure. A modified side electrode is also used here. It has a thinner part at the point of contact, and together all this gives a clear, stable spark, regardless of the degree of operation and the features of the motor. In fact, this is an analogue of a candle from NGK and, as they say in the reviews, the quality, although inferior to the original, is insignificant, but the candle costs much cheaper, and even taking into account the reduced period of operation, the savings are obvious.

Spark plug manufacturers are constantly on the lookout for new materials that can improve life and performance. Today, iridium and platinum candles are considered the most advanced. These are the best materials, but this manufacturer went even further and made the central electrode of double platinum, that is, doubled its amount in the alloy. He also worked on the side electrode. It uses gold plating and the block itself is modeled, and quite difficult. At the same time, the candle did not cost fabulous money. Yes, it is not the cheapest, but it cannot be called prohibitively expensive either. In general, a great option that will replace the original module.

Studying the characteristics of this spark plug, it becomes clear that it is suitable for most vehicles operated with an average load. This is a platinum model with a 1.1 electrode gap. She has two side braces with a slight recess and a long skirt. According to tests, such candles are not only durable, but also save fuel. At the same time, one piece costs only 220 rubles, although it is supplied in a minimum configuration of 4 pieces. In fact, this is an analogue of Denso candles, but much cheaper and with free shipping. The reviews are very positive, and they praise both the product itself and the seller, who quickly responds to the incoming order.

The spark plug tester shows if there is a spark and how it is distributed between the electrodes. In fact, the device is very simple, which we see in this product. There is nothing superfluous here. Only one regulator that allows you to set the desired speed and two indicators showing whether there is power on a particular module. For protection, a transparent cover is used, and in its open position the tool will not work. But the plug is exclusively American standard. If you have an ordinary European socket, take care to buy an adapter and a step-down transformer. The tester works from a network in 110 volts.

All testers of this type act plus or minus the same way. They will not say much about the condition of the candle, and, in fact, they are able to simply check its performance. Despite this, the price of some models is prohibitive, but Aliexpress is good because you can always save money here. Now we have the cheapest classic tester with two connectors. It shows if there is a spark and what is its intensity. Revolutions are set in the range from 1000 to 6000 per minute. In principle, this is quite enough for a home master, which means that there is no need to overpay for a more expensive product with the same content.

This tool is more suitable for a professional master, and it hardly makes sense to buy it at home. There are many connectors, which allows you to test five modules at the same time. Yes, this is convenient, but in everyday life you can easily get by with two entrances, like other models. The main advantage here is a very smooth and precise adjustment. You set the speed not with the handle, but with the help of the plus and minus buttons. The data is displayed on a digital display, that is, you can clearly see what values ​​are currently available. This makes it possible to carry out more subtle diagnostics of spark plugs, which in most cases is simply not needed by the average user.

Spark plugs come in a variety of designs and shapes. In particular, the caps differ and this becomes the reason that the tester must be selected for a specific model. But this tool eliminates this problem, as it comes with removable nozzles, which are easily installed in a seat in a couple of minutes. This makes the tool versatile. Otherwise, it’s a good tester with the ability to set rpm in the range from 500 to 6000. True, there is no fine tuning, and even setting the handle between two digits does not give a result. However, for most users this is not necessary.

AliExpress also has its own market leaders, and if we talk about testers for various purposes, then one of the best manufacturers in this area is AUTOOL. This tool belongs to the semi-professional category. It allows you to fine-tune the speed settings. These are not specific numbers with a gap of a thousand units, but very accurate values, which makes it possible to use the tester with almost any spark plug. The manufacturer values ​​​​his reputation very much, therefore he offers to return the money within 3 years if the tool fails. By the way, reviews confirm the quality and reliability.
