BMW 3 Series B48 Do it yourself to replace the spark plug
The conservative point of the B48 spark plug is to change the oil twice, which is 240,000 yuan per change. It has already run more than 50,000 yuan. You can change it and learn about 1200 yuan for the 4s continuous working material. I change it more than 500 yuan, including 200 yuan. Tools.
Without saying much, get started.

More than 50,000 kilometers

The model number is 8b8s94201

unpacking

Four-pack, bought from the milk tea house NGK flagship store, 349.

Remove the 2 plastic covers first

To remove the ignition coil screws, use the E8 Torx Sleeve

Remove screws

Push out the white plastic of the clip, hold the white clip with your hands and pull it out

Pull out the wire thread and pull out the ignition coil

Tool combination for removing spark plug

Universal 14m ultra-thin spark plug sleeve, 75mm adapter rod, 55mm universal joint, torque wrench (joint is 3/8 Zhongfei)

Install the spark plug sleeve assembly

It’s a little dirty in there

Find a thin tube and modify the vacuum cleaner connector

I took out the burner plug and found that there were fine debris inside, which could only be sucked out with a vacuum cleaner. I found a tube (you can also use a straw for drinking milk tea) and glued it to the vacuum cleaner connector with a transparent glue.

the first

First, the great gods will take a look at how the burning is going?
I disassembled one after another and installed the torque wrench to 23.

Pull out this pimp

Stuff the sponge in

and remove the most troublesome one.

Change four for a group photo

The innermost one was the most troublesome. I removed the plastic parts on both sides and the two screws on both sides of the balance bar. I found that there were still two screws on the middle wiper, but I didn’t want to remove them, so I squeezed the sponge on the lining. Inside, based on my experience in removing the connector of the line card in the front, I used something to hold the white clip with one hand and a screwdriver to hold the connector with the other, and I came out just like that. In other words, those things don’t have to be disassembled!
After replacing it, check all the screws, reset the removed ones, and once the car is lit up, you’re done!
Finally, I would like to thank the Home platform and all the big guys in the jar who spoke freely!
Before and after EBC, the redskins are on the road, and the next step will be trouble!
