The New Year is coming soon, and everyone knows how to buy new clothes and buy New Year’s goods. The same is true for cars. They are usually diligent and hardworking, and they have to make preparations during the New Year.

I had just done minor maintenance on the 4S before New Year’s Day, but the oil filter was not changed. Considering that it was almost 140,000 kilometers away, I simply changed all the ignition coils, spark plugs and air intake styles this time.
I can’t understand it, I don’t have to read it anyway
These are the four
Ruthenium gold is said to be the highest level?
The matter of changing the air intake style is a bit ridiculous. One day five years ago, my family drove to maintain it. I don’t know whether the 4S was intentional or foolish, but the KN was thrown away and replaced with the original factory one-time. It took me a long time to realize that, so in recent years, it has been a direct connection to the middle section of the original factory.
Helpless, I bought a new one…
The spark plug should have been replaced every 80,000 kilometers, and the ignition coil has been the original factory for 10 years. Taking advantage of this opportunity, I replaced the NGK ruthenium gold RX spark plug and the ignition coil with the SPE pro4 generation ignition key.

Not cheap, nearly 800 per stick
Comparison between original factory and SPE
The original factory is also NGK, which is not bad
It’s already like this, no wonder the fuel consumption has increased
Load the code neatly
I just finished changing and ran a few kilometers to refuel. To be honest, I haven’t felt much change yet.

I don’t know if it’s a psychological effect, but the speed increase in the middle section feels a little light, but the fuel consumption feels obvious. In the past, the fuel consumption of this section of the road was cleared by the fuel gauge and the fuel consumption was around 13, but this time the same driving style was 11.5.
I have spent a lot of time on the car in the past week, mainly doing my own crystal plating. Once every other day, I spent two hours in the basement after coming back from work.![]()
I used a polishing machine to polish it first and then plated it 4 times. Fortunately, I didn’t have any back pain.![]()
It does look the same as the new car. The seller said that the crystal plating will reach the hardest target in 7 days and will see if it has anti-scratch effect next week.
The cumulative result of 8 hours of hands-on: it is really bright and does not contain water droplets
Let’s just do this for the time being. After the New Year, we will replace the first section of Sanyuan. The 140,000 kilometers should be almost blocked. If it is replaced, it should be smoother. In theory, the fuel index should be improved. Then, if you change the tooth brush ECU, you can add about 20 pieces. It doesn’t count how hard it is. If you brush the turbine at any rate, the main reason is that the driving feeling will be better and the subjective feeling will be easier to drive. Then basically it’s like this, it won’t be big again, and it can satisfy daily use and occasional passion.

Finally, I wish you a happy New Year in advance![]()
