good material, hopefull can used for long lasting


We use it for Initial Model VTR. In the winter, I could not afford to catch Chalk, but I feel that the stability has been improved remarkably! Since only two months have passed since I exchanged it, I am not sure about Cospa and exhaustion However, I receive the impression that it is comparable to that just after I replaced it for the moment. I like the extent that it will probably be Windshield IRIDIUM for the next exchange as well

I exchanged Plug because it exceeded 11000 km. Although it is an impression of about 500 km,
The attachment of Axel at 1500-3000 rpm improved, and the high rotation also turned well
I think. 5 speed 40 km is easier to run. Just 2000-3000 Partial
I feel that the area became irritable, and it became difficult to maintain a little with. I want to increase the vibration...
Because the heat value is not matched, the original Plug may be more comfortable for regular rotation. I am worrying about returning..
Looking at you..

It will be a good price if we arrange 4 pieces and there is no change that can be experienced in fuel consumption and running feeling so there is no visible return. (I do not know the invisible part. )
My car will soon be 20 years old so I bought it for something like an adult celebration.
It is completely self-satisfying..

Originally it is an exchange from the Normal plug without deterioration,
If you replace it from a deteriorated state, you may feel some change.
The thing is not bad, I wish to judge again whether I try to ride the distance.

Used in cb400sf nc39.
Since the Normal plug completely failed, this time I got excited and I tried it as an Iridium plugs.
Fuel economy, Power feels up.
We plan to use this plug when we also exchange next!

We exchanged from Standard Plug BP 5 HA at about 11500?. I feel a sense of stability improved when Idling. I will do the same thing when I exchange next time as well.

It is almost time for replacement, so it is a purchase exchange. As for VTR, it is an exchange as thinking that it is strange that the Plug on the back side becomes bad early,. The rear Damage is terrible as you can see in the photo. After swapping it will turn nice to the good feeling. A new item is good. Ilijium's Plug feels that there are few ways to attach Black Isuzu. Feeling Power seems to have gone up? As it is a regular replacement part, let's change Don Don. Whether there is bulk buying at the time of Sale - - -

I installed it in SC 57.
It is an impression of an amateur.

Full power
Power commander installation (Map is DL from Site)
Comparison with OEMPlug.

Idling is not stable.

It gets stuck at low rotation.
Especially when you start off on a town ride it will be noticeable.

Also, if you cruise around 4000 to 6000 turns, After Fireia will happen. "Pan!" Although it is not quite so good you will hear a pom-pombolic sound.

I feel that it is not much different from NORMAL around the power band.

Can you feel the difference when you run Circuit.
In town riding this plug was unnecessary.

I compared NGK and DENSO's Iridium plugs of the same class.

■ Center electrode diameter
- NGK 0. 6mm
- DENSO 0. 4mm

■ Ground electrode shape
- NGK TaperCut
- DENSO TaperCutU Groove ground electrode

Comprehensive comparison At Point, DENSO looks superior to Specifications from NGK, but DENSO seems to be more expensive than that. I tried picking DENSO after I got lost this time.

As impressions after installing the Plug, I was unfortunately insensitive to me, I did not feel the big difference with the Normal plug, but I am satisfied because the Plug became a new item and I could refresh moodily.

After changing the Plug of VTR to Windshield IRIDIUM, since the Large body passed one year, exchange this time.
Looking at what I used for a year, Black is growing around, but the tip seems to be not worn so far. Still the new item feels good.

Since this exchanged Plug was the same number as ZOOMER, I added it to ZOOMER and it was felt that Response had gone up.
Honestly It may be because the previous Plug has never been changed - - -

I decided to improve the poor startability of the XR 250 in the winter and eventually I reached the Iridium plugs.

Before Plug, change to AICancellation & OEM Carburetor's Main jet # 135 → 140 etc etc. Even though ... startability is bad.. There were times when Battery's charge ceased to exist.

And, referring to various reviews of the people, Iridium plugs replaced the place, the startability has improved significantly. Because the timing of replacement is in mid-May, we can not confirm the startability in the winter, but it is a dramatic change as a result of comparison with before installing Iridium plugs.

Also as for the running surface, the Engine feels to turn well. It may be due to mind.

It is satisfying Large because it is not a much higher translation than the ordinary Plug at the price as well.

When setting the carburetor Windshield IRIDIUMetc. I bought it because the Normal plug is better.
Since it is trusted NGK, it can be used without problems. It is an exchange from Windshield IRIDIUM, but I feel that the performance has dropped slightly again

I bought it for two daughter's mopeds and exchanged it. 1 unit is a used car and it is exchanged for about 8 thousand kilometers after purchase. The other one is about 2 thousand kilometers, but I exchanged it. It feels like the Engine is spinning well.

Performance is Standard. It is Merit of the largest Large that you can purchase cheaper than the shop.. You can save time and time going to the store.
It is a recommendation to buy a single cylinder of Motorcycle as a spare.
