Discovering the Spark plug that looks like the face on the product explanation screen of Wa Big who happens to be found. Regarding its use, this plug which encourages watani attachment to the ignition system. The purchase decided immediately for a car that meets the conditions! When looking at the real thing, Steel color which Blue took first gets an eye out. The center electrode of the tapping was NGK - Compared to DR8EA, it will be positioned more towards the center of the combustion chamber by 1 mm or more, which will increase expectations for combustion efficiency Up. However, looking at the details, I can not deny the feeling that it is more complicated to make than JAPAN's Plug. BALI of the center electrode and screw terminal type terminal are obviously off center. , I feel a little cheapness because I am watching JAPAN items with high precision from the usual. However, if you actually use it and have sufficient performance and durability, you can say that it is not necessary to request such parts that are not normally visible. I installed it immediately, but the exchange itself is exactly the same as regular Plug exchange and there is no particular problem. The accuracy of the Screw part seems to be a passing point. When I try to cover Plug cap, it is Fashion that Blue 's Steel color looks sharp. And Engine start! - - - That sounds exhaust sound from Mild something more than usual. Because it is a single cylinder, there is a place called Dododo, but it is called Toto. However, rather than being cheesy rather than luxurious - - -. Also, the warm exhaust gas Gas in the winter season has Gas smell, but it feels like it has been relaxed. Impression that Engine braking became Mild when I actually ran. I have stopped playing. Furthermore, Engine vibration seems to be decreasing. Since Cowl was wearing, engine oscillation was swaying the edge of Cowl, as it was Big Li after replacing the Plug, it became impossible to see it. It is feeling that the rise is also powerful though it is Mild. I am surprised that there is such a change with just one Plug. I ran about 20 kilometers, but I did not feel Minus factor. I would like to see the impact on fuel economy and the durability of the plug itself. It is limited to strong motorcycle of watani equipped car or ignition system, but it is recommended plug at the first impression.
Filter's fold was uneven when I took it out of the box first.
Moreover, the Seal part leaked out from the Gold belonging part of the Filter and it was coming out from Hami. In this case, Seal did not get dirty, but Seal entered the Engine, so it was not possible to use it, so we decided not to use it.
The attached O-ring was also unfortunate because its thickness did not match and it was unfortunate.
I used model number KN-401 in ZrX 1200 Rnitial Model 01. Two O-rings and YOSHIMURA Sticker were enclosed and could be used normally. In terms of reliable Brand performance, I think that it can be used with confidence, but the price is slightly higher, but let's buy it thought that insurance was put on it.
