About spark plugs for UAZ Patriot with 409 engine (Euro 4)

One of the main leaders among SUVs in the Russian Federation is undoubtedly the UAZ Patriot. The manufacturer of this car decided that the best option would be a 409 engine, fully compliant with Euro 4, and this is really an excellent and, perhaps, the right solution for such a car. Power units used in European countries by well-known automobile brands have begun to actively gain relevance in the Russian market and CIS countries. The engine, as many people know, works thanks to an important element - it’s not hard to guess, spark plugs.

The equipment coming from the factory will work without any problems until the odometer shows a mark exceeding 20 thousand. km of run, but only under this condition - the fuel used for the car must certainly be of high quality, or the part will deform very quickly. Drivers know very well that it is now extremely difficult to find really high-quality gasoline and diesel fuel. Many Russian gas stations dilute fuel. In such conditions, spark plugs work with great difficulty and can quickly fail, and this is absolutely no fault of the car owner.

The performance of spark plugs depends on high-quality fuel

There are a large number of modifications of power units for the Russian most popular UAZ Patriot. The manufacturer produces different engines that comply with Euro 4 standards. There is no classical production technology, so it turns out that there are no identical models. Each individual company improves the “product” it produces as it sees fit.

If you are faced with a situation where the spark plugs have worn out and it’s time to change them, don’t get lost, everything is quite easy if you have the right information and choose the right spark plugs, because the performance of an SUV engine depends on quality parts. Of course, you can take advice from a specialized store, but no one knows the car better than you.

Every UAZ Patriot, without exception, powered by a 409 engine, has the following characteristic features in the system:

• Multiprocessor injection.
• Work on gasoline.
• 4th cylinder.

The car's instructions separately talk about the power unit, and some recommendations from the manufacturer are indicated on it. The optimal fuel for an SUV is Euro 4 gasoline. This fuel allows the mechanism to operate correctly and for a long time. Naturally recommended fuel is the best for the engine, but it is not the only one. Of course, you can fill the Patriot’s tank with other gasoline, but the most important thing in this matter is quality. Bad fuel will lead to failure of the spark plugs and disrupt the smooth operation of the fuel system as a whole; the car owner must always remember this, otherwise the engine will break down.

What changes will happen if you fill the UAZ tank with another fuel:

• The spark plugs will become more dirty and burn out accordingly.
• The car will accelerate much more slowly.
• • When accelerating, a knocking sound will appear, which is completely absent during normal operation of the fuel system. Use the correct fuel for your car's engine; this is a basic requirement for every owner, otherwise you will need regular replacements.

How to choose the right spark plugs for a Patriot engine

How stable and stable the engine operates depends entirely on the state the spark plugs are in. Also, the serviceability of the spark plugs directly affects fuel economy, the power of the power unit, its so-called starting properties, and much more. It is important to choose spark plugs, given that the car has a 409 engine. Let us remember that high-quality products consist of alloys of platinum and another metal - iridium. The use of these modern materials allows us to produce very reliable structures. These spark plugs are therefore not cheap, but every driver will understand that they quickly pay for themselves. Their objective service life ranges from 60 thousand km or more.

Another equally bad option is also modern plasma-prechamber products. They have the following advantages:

• Long service life.
• Thanks to the correct shape, there is no need to adjust the gap.
• The self-cleaning process is much better.

When choosing the most suitable configuration, take into account, among other things, the material from which the candles themselves are made, the country of manufacture, plus pay attention to the length of the selected model, its gap shape and thread.

For the domestic UAZ Patriot, spark plugs with the following parameters are ideal:

• There is a built-in resistor.
• Length from 19mm.
• Thread dimensions must be M14x1.25.
• The gap for a spark with these characteristics is 0.7-0.85mm.

For the motor we are considering, A 14 DVR sections are perfect, you can also use analogues. Why are they best suited for the UAZ Patriot? Let us next consider the decoding of the product.

• “A” is the thread pitch, diameter. In our case it means M14×1.25. This design can be mounted to different sizes.
• “14” is a capital number, so to speak. An extremely important parameter that helps determine the temperature characteristics of the spark plugs.
• “D” - this parameter determines the length of the thread, which in our example is 19mm.
• “B” is the parameter of the insulator thermal cone protrusion. This equally important indicator is responsible for how quickly the spark plugs warm up after starting the engine.
• “P” - there is a built-in resistor. It is necessary in order to reduce the level of interference present for the electronic control unit of the power unit and radio equipment.

Choice

After the factory spark plugs on the UAZ Patriot wear out, they need to be replaced with new ones, but before changing them, you need to make a choice. Now there are a huge number of manufacturers, and design options, they can be:

• Silver;
• Platinum;
• Yttrium;
• Iridium.

therefore, the car owner may be confused at the sight of such a huge selection. It is recommended to consult with the seller before purchasing.

Before buying spark plugs for a UAZ Patriot, you need to figure out what engine is installed in the car. This SUV is equipped with a ZMZ-409 gasoline power unit with four cylinders and microprocessor injection. To achieve maximum results, it is recommended to fill in Euro-4 gasoline; the car works best with this fuel; filling fuel below this value is undesirable, as this can lead to negative consequences, for example:

• They will become slower to gain momentum;
• Candles will quickly become dirty and burn out;
• When accelerating, the valves begin to knock.

Based on the installed engine that is fueled with Euro-4 gasoline, you can choose those spark plugs that are designed specifically for this type of engine. Iridium and platinum are considered more durable and expensive; their minimum service life is about 70,000 kilometers. It is also worth paying attention to plasma prechamber products as they have a number of positive properties, such as:

• Good self-cleaning;
• Long service life;
• A non-standard device, their body acts as a side electrode.

When choosing, in addition to the manufacturer, you should pay attention to technical data such as: clearance, length and thread of the product. For engines installed on UAZ Patriot, spark plugs that have the following parameters are suitable:

• Thread with a length of at least 19 mm, and M14x1.25;
• Built-in resistor;
• The gap in which a spark is formed is from 0.7 to 0.85 mm.

The product with such data is suitable for this type of engine. As a rule, A 14 DVR spark plugs or their equivalent are used.

General recommendations for replacing spark plugs on a UAZ

Installing new spark plugs on a domestic UAZ Patriot is not at all difficult, you can do it yourself, the main thing is to follow the step-by-step instructions. To replace, you will first need to remove all 4 spark plugs present. This is done as follows:

• It is necessary to locate the tip with the seal.
• Remove the spark plug using a specialized spark plug wrench.
• If defects or damage are found, the spark plug should be replaced.

When replacing with a new part, you should pay attention to whether there is carbon deposits on the working surface. If there is a strong deposit, this indicates that the engine has recently been running on an over-enriched mixture, so to speak. The mixture should be light brown in its normal state.

Important! If out of all 4 spark plugs only 1 fails, then all elements should still be replaced.

Specifications

The ZMZ 409 Euro 4 engine has improved technical characteristics compared to its older brother. Thus, the power unit, due to the fact that it was designed on the basis of the 409, received high technical characteristics and endurance.

In addition to the Euro 4 standard, there are a number of modifications that are worth considering:

1. ZMZ 409.10 is the main motor, meets the Euro-2 environmental standard. Power 143 hp

Spark plugs for UAZ from trusted manufacturers

The list of candles that are ideal for the UAZ Patriot consists of 5-7 options. The most popular brands producing products: Bugaets, candles from Denso and Bosch deserve a lot of attention, candles from NGK and Brisk would be an excellent option, and don’t forget about Finwhale.

Here is a brief description of spark plugs for UAZ Patriot from some of the above-listed manufacturers:

• Products BOSCH Platinum Plus FR7DPX. Their quality is average, but their service life is quite long. Using such spark plugs, you will definitely notice good engine power. The downside is the difficult start of the power unit.
• Budget model Brisk DR17YC. These products are enough for approximately 3 thousand kilometers. It should be noted that there is some instability during operation.
• For smooth operation of the “engine” of the AU 17 DVRM. At 800-5000 rpm there is no twitching or delay. There is noticeable throttle response, plus low-end stability, plus good power from the power plant.
• Another option is NGK BCPR6E. The price is no more than 550 rubles. Such candles perform well at the initial working stage.

The compiled rating of spark plugs for UAZ was selected taking into account the low cost, which is good news, and moderate performance during active use.

Malfunctions and repairs

No special malfunctions or problems due to engine operation were noticed. On some vehicle models, it was noticed that injectors quickly failed. This problem can be easily resolved by replacing all injected elements. The timing chain can last about 200 thousand km, but it happens that it doesn’t last even 100 thousand km, depending on your luck.

A major overhaul of the engine should be carried out after 250,000 km, but with proper operation and maintenance, it may happen that the engine will withstand 300,000 km.
