Dangerous filters: how to distinguish a fake from the original? (part 2)
Purely theoretically, the size of the oil filter is unimportant. The main thing that came up on the thread and landing surface. But there are much more important characteristics. For example, the pressure at which the bypass valve will operate is important. We will not fall into the abyss of filtering and confine ourselves to the conclusion that it is wrong to select filters according to thread and seat.
It is only necessary to install what is prescribed by the manufacturer. And if the filter is made poorly, then the consequences can be very diverse. In the worst case, it is simply squeezed out and the oil flows out into the street. Here, however, a motor stop after the oil pressure lamp comes on can save (and even then not always). But, for example, if the spring of the bypass valve for some reason was not strong enough, then you can drive with an actually idle filter in oil that does not pass the cleaning, and not even know about it. It is one thing when the bypass valve allows the crude oil to get directly into the engine in difficult or transient conditions (in cold weather or when the gas pedal is pressed suddenly), the other thing is constant driving with the valve open in the filter. Here you can reduce the engine resource several times. But I repeat: the physical size of the filter does not affect this parameter. Nevertheless, such a filter would alert me. Yes, 200 rubles cheaper. But why? Calm, in my opinion, is more expensive.
Now we get the second pair: the original 2630035531 and the analog Pmc PBA-001.
We have already discussed the packaging of the original; let us move on to the analogue.
In principle, all the necessary information about the filter is on it.
The filter itself looks much better than the previous counterpart. Neat rolling, detailed installation instructions. There is no Russian language, but for a filter made in Korea, this is not scary. The font on the body is a bit blurry.
But if you compare this filter with the original, you can find one oddity.
See the holes around the bottom perimeter? Through them, dirty oil enters the filter. Through the central hole, the cleaned oil goes into the engine. On the original, the anti-drain valve is very clearly visible – such an elastic band of an orange hue. But on the analog valve is not visible. If you shine inside, then you can notice it somewhere unexpectedly deep. What he does there is not entirely clear. Two questions arise. First: will the oil flow from the filter into the sump after each engine stop? And doesn’t it turn out that every engine start is dry without oil? The second question: will dirty oil flow from the outside of the filter into the inside with refined oil? Preventing this is one of the most important tasks of the anti-drainage valve. And for some reason he was very far from the inlet openings of the lid.
And the size of the filters again turned out to be different. A trifle, but unpleasant.
It is worth noting that this analogue clearly wants to be similar to the original. Look at the first Kia filter: the same blue color, a very decent assembly, the absence of Russian-language inscriptions … And also a hologram, which, as we found out, may not be. But here she is, just in case. Probably for greater persuasiveness. But only on both original filters the anti-drain valve is visible very well, but on the analogs – no
It will not be enough
The very fact that Kia and Hyundai have a fuel filter can be called joyful: you won’t have to change it together with the pump. And you don’t even have to cut the floor under the back seat. It remains to see what these filters are.
We have two of them: the original (311121R000) and its analogue from Nipparts (N1330330).
Frankly, both packages look very nice. Neither the original nor the analogue have any blurry fonts or unprinted letters. And the Nipparts box is even sealed on top. But the Kia filter inside the box is also packed in polyethylene.
In general, it is impossible to find fault with the packaging.
Externally, the filters are very similar. Differences are only in small details. For example, the Nipparts filter’s connector is coated with some kind of oxide, and with Kia it is shiny.
Nevertheless, there is one thing that cannot be passed by. We look at the photo below.
Do not you think that the diameter of the nozzle of the original filter is larger than that of the analogue (the original is the one with a pink tint and inscriptions)? So it seems to me. We take a caliper and ask his opinion on this matter.
And his opinion is quite certain: with the diameter of the fittings, the analog manufacturers did not guess. In the original, it is 6.8 mm, in the analogue – 5.8. The absolute difference in millimeter with a small diameter gives a relative difference of almost 17%. And this is a lot. Maybe that’s why dissatisfied comments from the category “dirty original was better than a pure analogue” are found in reviews. However, this is an extreme degree. In the “light” version, the situation will not be so terrible. Just the pump motor will work in a more intense mode and die a little faster. But on the filter, you can save two hundred rubles. But does anyone need this?
Breathe and not hurt
Now let’s move on to the most underrated filter in the car – the cabin. Well, if the car is serviced by a dealer: there is no way to get out of replacing this consumable. And what will happen if this filter is not changed? First, it will clog up with dust and dirt to the state of a felt felt boot, which will lead to a decrease in the efficiency of heating, air conditioning and ventilation. It will be cold in winter, hot in summer, and all year round it will be supplemented by foggy windows. In addition, there is a high likelihood of catching all sorts of human sores in the car: microbes quickly multiply on a constantly hot and humid cabin filter. In the car by this time it will already stink of mold and rot, which in itself is already unpleasant. In short, the cabin filter is a useful thing. Let’s see how the analogue here may differ from the original.
Our original Kia part is 971334L000. The analogue is a Miles part with AFW1309. Such filters are on the mass Rio and Solaris.
We will not compare the packaging – it is just different. At Kia, the filter is simply sealed in a plastic bag, at Miles – a traditional white cardboard box with a crooked label for this manufacturer.
Both filters are marked on the side. Both there and there – pretty high quality. The dimensions of the analog millimeter to millimeter coincide with the dimensions of the original part. And that is wonderful.
It would seem: how can you screw up in the manufacture of a simple cabin filter? It turns out you can. Compare the crease frequency of the filter element on the two parts.
Above is an analog, below is an original. I did not spare the time to count the folds. There are 42 on the original filter, 36 on the analog. It seems to be a very insignificant difference, but the filter area in the second case is noticeably smaller. Most likely, it will clog slower. But filtering is likely to be worse. At least due to the smaller area. True, the material of the element still matters here, but we will not be able to conduct a comparison of these materials with all our desire.
To be honest, this difference is not the worst thing in life. But still, a similar analogue cannot replace the original part. And if such a filter suddenly starts to let all the street smells into the cabin … Probably, it’s not worth the risk.
