Owners of Lada Largus 1.6 choose spark plugs from the German brand BERU for their high-quality assembly and availability. The car accepts them with gratitude: the engine starts with half a turn, runs smoothly and is more fuel efficient. The spark plugs effectively “light” for the entire guaranteed 30,000 km. But, judging by the reviews, few people last longer. Some Largus owners prefer to change them after about 20,000-25,000 km for fear of not starting in the cold. At the same time, there are practically no complaints about earlier failure of spark plugs. In general, a good option for a budget 8-valve model.

Advantages and disadvantages

  • Effective in any weather
  • Economical
  • High quality assembled
  • Rarely work after 30,000 km

How to extend the life of spark plugs on Largus?

The most important rule that will help extend the life of spark plugs on the Lada Largus is periodic monitoring of their condition. On gasoline engines, it is enough to systematically diagnose, clean and check the gaps between the electrodes. The maintenance can be completed at this point, since the element is quite unpretentious.

Carbon deposits are removed using a special brush with soft metal bristles. If you cannot cope with the contamination, you can place the candles in a container with ammonium acetate, but before doing this, the part must be degreased. After 24 hours, carbon deposits can be removed with a cloth.

Attention! If, when servicing spark plugs, there is a need to use aggressive chemicals, then there is every reason to carry out engine diagnostics. Heavy carbon deposits on the electrodes occur when there is a serious malfunction of the power unit.

Another important parameter when checking spark plugs is the size of the gap between the central and side electrodes. The normal value is indicated as a marking directly on the surface of the part. You can determine the gap using a special feeler gauge with a round cross-section; a flat feeler gauge is not suitable for these tasks. You can adjust the indicator to a normal value by bending the side electrode.

There is no need to service spark plugs on diesel engines. On such engines, the part has a complex design, so during diagnostics there is a possibility of the spark plug breaking off. Therefore, we do not recommend unnecessarily removing spark plugs on diesel engines. Although this certainly does not concern Lada Largus owners, because such models with a diesel engine do not come off the assembly line.

  • Center electrode material: nickel
  • Heat number: 10
  • Gap, mm: 1.0
  • Resource, km: 30000

Like other representatives of our rating, these spark plugs work flawlessly in both summer and winter. Some cars leave the assembly line with them and consistently drive 30,000 km before the planned replacement. Owners of Lada Largus notice that the new spark plugs start the engine perfectly, which even idles without failure. Gasoline consumption is reduced by up to 10%. However, towards the end of the spark plugs' life, their effectiveness in relation to the engine decreases slightly. Few people leave them running longer than the recommended mileage, because the engine loses its power, which means gasoline consumption increases noticeably. Although this is observed when using other candle models beyond the deadline.

Advantages and disadvantages

  • Reasonable price
  • Reliable build
  • Standard resource
  • Ineffective after the resource has expired

Which spark plugs to choose for Lada Largus?

Without spark plugs, it is impossible to ensure ignition of the fuel mixture in the combustion chamber of the power unit. The manufacturer of Lada Largus claims that the life of standard spark plugs is enough for 30,000 km. If you follow the rules of operation and maintenance, this figure may increase, but it is still better to adhere to the recommendations of AvtoVAZ. Otherwise, you may encounter problems such as:

  1. increased load on the catalyst;
  2. reduction in engine power;
  3. uncontrolled detonation of the fuel-air mixture;
  4. Unstable operation of the engine when driving and idling.

The manufacturer installs spark plugs on the car called Champion Ryclc87, as well as Sagem RFN58LZ. You can exchange them for original ones or choose an analogue from another brand. There is a wide variety of models on the market, which makes it very difficult to choose. Much depends on the type of engine that is installed on the car. For example, for the K4M engine, the automaker advises using original spark plugs from Renault called 7700500155. For an 8-valve power unit, it is better to give preference to 770050016, also from the Renault brand.

Attention!

You cannot install spark plugs from different manufacturers. These parts are replaced exclusively as a set to ensure similar performance in each cylinder.

The engines with which the Lada Largus is equipped have 8 or 16 valves. Such power units allow the installation of not only standard spark plugs, but their main parameters and characteristics must correspond to the factory ones, including:

  1. leg thread – M14;
  2. the main part should be 19 mm in length;
  3. The installation size corresponds to the 16th number of a special key designed for dismantling and installing spark plugs.

Judging by reviews from car owners, the actual service life of standard spark plugs is 50,000 km. This indicator is possible with moderate operation of the machine, as well as regular maintenance, which should include inspection, removal of carbon deposits, and measurement of the gap size.

The author of the popular Youtube channel “Ildar AUTO SELECTION”, Ildar Sibgatullin, shared useful recommendations: “The spark plugs should be removed only after the engine has been preheated to operating temperature. When installing, each candle should be lubricated with non-stick grease, which will facilitate dismantling in the future. It is important to maintain the tightening force to avoid unpleasant moments.”

Causes of spark plug failures on Lada Largus

Before installing new spark plugs on a car, it is necessary to carry out diagnostics and determine the reasons for their failure. The most common signs of poor spark plug condition, which can be determined visually, include:

  1. Carbon formation.
    The first reason for the appearance of soot deposits is low fuel quality. Carbon deposits are deposited on the surface of the electrodes due to excessive amounts of oxygen in the fuel-air mixture. Another provoking factor is the ineffectiveness of the air filter, which often occurs when it is dirty or damaged. In more rare cases, carbon deposits appear as a result of breakdowns of oxygen or temperature sensors, as well as malfunctions of the injection system.
  2. Oil deposits
    . This symptom indicates wear of the piston group elements. Oil deposits occur when too much oil is added to the engine.
  3. Yellow plaque
    . This sign requires the driver to pay attention to the quality of the fuel, or rather its composition. The presence of a large number of additives in the lubricant and fuel colors the surface of the spark plugs red and also yellow. The Lada Largus engine reacts sensitively to various chemical additives in gasoline, so before use you should analyze the feasibility of using additives.
  4. Intensive wear of the central and side electrodes
    . This problem occurs when the ignition settings are incorrect. We also often see this picture when valves wear out. The third most common reason is the use of low-quality fuel, as well as aggressive additives. In particularly advanced cases, the electrodes may even melt.
  5. The wear rate and performance of spark plugs are affected by the quality of materials and production technology. That is why we recommend choosing parts from trusted manufacturers, for which we have compiled a list of the best options.
