VV5S Ultimate Edition, which spark plug to use

Talking nonsense, a lot of riders opened their mouths to ask if they could save fuel, at first I was not used to it, spark plug home riders are not all like to play with the car, what is this mixed into, hey, it seems that everyone has bought a lot of houses, and now there is no money to refuel, so I still recommend to you spark plugs with better fuel-saving effects.

First of all, I will review with you what kind of spark plug costs oil: electric, fine, fast jumping, this kind of spark plug is more suitable for extreme speed but after all, it costs oil. Therefore, Denso and Torch, which are known as the world's thinnest millimeter electrodes, are excluded, and I do not recommend them.

Bosch doesn't think about him anymore, and the rest is NGK and Champion. And the original factory is NGK spark plugs.

The long thread is VV7 spark plug, the short thread is VV5 spark plug, these 2 are NGK iridium platinum spark plugs, let's talk about the Great Wall WEY VV5 VV7 These 2 original spark plugs.

This is the original spark plug for the VV5 SIFR6B7G mm Iridium center electrode, platinum side electrode with a calorific value of 6 degrees and a spark plug gap mm.

We have always had doubts about the workmanship of NGK spark plugs, isn't it, it's really good, but the manufacturer requires 20,000 kilometers to replace, and I always feel that there is a pit.

Let's take a look at the Great Wall VV7 spark plug:

The electrode is very thin, 12 mm electrode, long thread mm, 7 degree calorific value mm gap, the same iridium spark plug, high performance iridium electrode mm.

Let's take a detailed picture of the electrode, it's not very shocking, generally, and then a few 2 retouched pictures to see if everyone is satisfied.

Outer packaging**, the real thing is slightly worse than this, on the photo;

It's very good to look at it this way, and the feeling of being tall is immediately there, but it's not bad, a spark plug almost costs a Grandpa Mao.

To be honest, this spark plug is really not sold badly, the spark plug home ordered 10 boxes of inventory in the spring Until now, it is still 10 boxes of inventory, waiting to lose money, there is no way, because the champion high-end iridium platinum spark plug 9003 and 9408 are better than these 2 spark plugs, regardless of the ** life performance, they can kill SIFR6B7G SILKR7E7G 96766

I'm in a hurry to get off work, I'll directly say the recommendation of the theory, the champion spark plug and NGK these 2 spark plug ratio, the disadvantage is that the quality is not as good as NGK, but the stability and life are not worse than NGK, the champion 9003 and 9408 are iridium platinum spark plugs, the design life is 100,000 kilometers, even if the use is halved, it will be counted as 50,000, and it is a millimeter iridium center electrode, and the performance is slightly advantageous. The spark plug clearance is less than that of NGK, the ignition is slightly larger, and the power and fuel-saving effect are less and have some advantages. In fact, the most exciting thing is the ** of the champion spark plug, the same iridium platinum grade
