[17 models of Jialu] JD purchased original German-made Doctor spark plugs + do your own replacement spark plugs.

September 4, 2024

The mileage of the last spark plug replacement was 72045KM; this time the spark plug mileage is 98660KM.
Almost 3W (actual 26615KM).
But it doesn’t matter. Anyway, it doesn’t matter if you do it yourself and change it frequently. I’m worried that if you don’t change the spark plug for a long time, the ignition coil will burn out!
I have encountered Polo before. The spark plugs have not been changed for a long time, which burns out three of my ignition coils. )
I remember that the NGK spark plugs I bought last time were made in China. The doctor I bought this time is actually imported from Germany.
Material: Dr. JD bought four spark plugs at the original price of 249 yuan, but the actual discount + preferential payment finally = 164.12 yuan.

JD is self-run and guaranteed by authentic products. Actual payment: 164.12 yuan.

At first, when I saw the packaging, I was quite repulsive.

Looking at it from the side, it is amazing that the origin is Germany.

It’s all in English or German.

It’s all made in Germany.

This package is really different!

Wechat directly scan the imported QR code to identify it.

It feels like it’s authentic. After all, I still believe in JD’s self-owned store.

This packing is also disposable.

Unlike the NGK I bought before, this package cannot be buckled back after it is removed. The glue is directly glued to it.

The box is also very exquisite. I can see the EAC logo on a lot of circuit boards. I don’t know what big factory it is.

The gap between the spark plugs is also marked on the box. There’s nothing on the NGK I bought before.

This paper ring, which is also stuck on it, will not fall off.

Is GERMANY surprised?

The paper ring is rolled directly on it!

Compared with the doctor who changed in the 4S store before, this is the domestic product.

This is the last time I bought the NGK paper ring, completely loose, very easy to fall off, but it doesn’t matter! It does not affect the quality of spark plugs.

This is the previously bought NGK spark plug and the corresponding model: 95463 should be 1.4T AE211 can be used!

This clamp is too easy to use. It is strongly recommended to buy one for less than 10 yuan.

This time to change the spark plug, I only removed this section of the tube, which is the so-called section of the tube with a resonant cavity.

Take a kilometer. The last time the spark plug was replaced was 72045km; this time it was replaced again after 98660KM 26615KM.

Remember to wear gloves and beware of injury.

Then unplug the wire harness from the ignition coil, a little tight and a little more patient.

Ignition coils pulled out by one arrangement; however, there should be no need to sort all OK.

The spark plug of the first cylinder removed.

Sort the spark plugs in turn, the spark plugs in the fourth cylinder are rusty, which may have something to do with the fact that I usually like to flush the engine cabin with a high-pressure water gun. The spark plugs in the first cylinder are white. This bothers me a little bit. Is it because I changed the spark plug myself last time? Not enough torque?

The first cylinder spark plug. White, some do not understand! It’s possible that I didn’t get the torque right last time.

The spark plug in the second cylinder is normal.

The spark plug of the third cylinder is also normal.

The fourth cylinder is directly rusty. It’s probably caused by my water gun flushing the engine. I hope so!

When installing, first use a short-headed extension rod and sleeve to gently put the spark plug in slowly and tighten it in hand.

16mm special spark plug sleeve, in which there is a rubber ring specially designed to jam the spark plug and prevent the spark plug from falling off.

There’s a rubber band in this.

Gently push up the brand-new spark plug and jam the rubber ring. It is not necessary to reach the position completely, otherwise when the side may be pulled out, the rubber ring will be left on the spark plug with the rubber ring detached from the sleeve.
This is followed by tightening the spark plug with a torque wrench or an ordinary wrench in turn.

Then apply this high-pressure silicone grease to each ignition coil, no need to apply it, as if it doesn’t matter.
I guess you didn’t put these insulating silicone grease on you even if you went to the 4S store.
