Windshield IRIDIUM has a life expectancy of 10,000 km?

GN125H started to breathe occasionally and I decided to replace the Plug along with cleaning the Air cleaner element.
Since it is a Windshield IRIDIUM, I thought it would still be Large durable for 10,000 km or so, but the electrodes were clearly deteriorated compared to the new ones.
About 10,000 km seems to be the limit for Windshield IRIDIUM.
After replacing it with a new one, the Torque feeling goes up and the breathing is gone.
Do not overestimate the longevity of Windshield IRIDIUM. View detail

Maybe it doesn't mean anything in particular...

I feel that the more solid the ignition is, the better the stalling and vibration, and the longer the service life (all of these things are true). I have a feeling." (Level)
Compared to the Standard Plug BP5HA, the price is 5~600 yen higher and more than twice as much, and yet the service life may be slightly longer. (Lol) 。
This may be one of the reasons why the old Motorcycle has almost one-shot startability in winter... View detail

GSX400 Plug replacement

I have been using the Meter for 20000 km and recently I felt that the starting performance was getting worse, so I replaced the plug.
Idling is stable even in recent cold weather with vigorous one-shot starting and a short warm-up time. View detail

Mood and performance UP!

[How is it used?
I got the D Tracker from a private seller, but first of all, I had to replace the plug. I decided to go out on a limb and install a Windshield IRIDIUMIX plug, which is about twice the price of the Standard Plug BP5HA.

Was the one you received as per Image?
The center electrode is very thin, but the appearance of the others is the same as the Standard Plug BP5HA.

Was the installation difficult?
Before removing the old plug, I carefully blew off the dust in the plug hole with AirBLOWER, removed the plug, checked the torque of the plug in the service manual, and tightened the new plug to 13Nm using a torque wrench.

How was your experience with it?
Hmmm, I can't tell the difference w
The D Tracker originally did not start very well, and this was due to the low jet (#35), so I installed #38 to improve the starting performance, so the Iridium plugs did not improve the starting performance. I changed the sprocket from the standard 14T to 13T for an acceleration type setting, and I don't think the fuel consumption has changed at all. So, unfortunately, I could not feel the benefit of the Iridium plugs (I cried).

[Included Parts:were they on?
None

[Was there anything that disappointed you?
I didn't have overly large expectations from the beginning, so I just thought, "Well, that's about the size of it.

How did it compare to other products?
The manufacturer's recommended replacement distance for high-end Plugs such as Windshield IRIDIUM for Motorcycle is actually 5,000km, the same as the Standard Plug BP5HA (general Plug). I heard that Plugs that use precious gold for both the center and outer electrodes (not for Motorcycle) can be used up to 10,000km. However, the MotoDXPlug for Motorcycle can be used up to 10,000km even though only the center electrode is made of noble gold, so it may be great? I have another Motorcycle (FZS600) with Standard Plug BP5HA CR8E, which runs over 5000km and is still in great shape even after 8,000km, so I dare Merit to choose a high-end Plug.... ......w I wonder if the high-end Plug can actually be used for 20,000km or 30,000km over 10,000km....... If so, I have a Merit to choose. I remember when I was writing this, my mini car may have run about 100,000km since I replaced it with Iridium plugs. It's a single cylinder, so it only needs one plug. View detail

A High Quality Spark Plug for your Performance Grom

About quality and texture: I am happy with the quality of the CR8EIX iridium spark plug from NGK, the fine iridium tip ensures a consistently stable spark and the trivalent metal plating provides superior anti-corrosion properties. About the feeling of use: With the ultimate design and technology put into the manufacture of this spark plug you get outstanding acceleration, high fuel efficiency and durability when compared to a standard NGK spark plug. Products to buy together: NGK also offer high performance spark plug caps which would also be desirable to purchase alongside the NGK iridium CR8EIX spark plug to remove any chance of the performance of the iridium spark plug being decreased. Difficulty of installation: The process to install takes about 5 minutes. Firstly, check the spark plug gap and adjust if required, then simply remove and install the spark plug and refit the spark plug cap securely. Not difficult to do. Cost performance and comparison with other products: Good costing as you are getting a better performing and more durable longer lasting spark plug as compared to a standard NGK spark plug, that is cheaper to purchase but is not as fuel efficient and will require changing more regularly which will lead to costing you more in the long run. About shipping and packaging: Sea freight was my preferred method of shipping due to the lower cost but currently this service is unavailable from Japan Post, EMS is much faster which is nice. Webike kept me updated on the status of my order up to when it shipped. The parcel arrived within the expected date range and was well packaged with no chance of the part being damaged. Any concerns, cautions, or advice when purchasing: The original Honda spark plug heat rating is 6. Recommended heat rating for the stock engine is 6 or 7 and recommended heat rating for a big bore or high compression engines is 8 or 9. View detail

Some vehicles were a little worse with Windshield IRIDIUM, as if there was some kind of compatibility. View detail

Impressions of use with two models

[How is it used?
D Tracker, used with NINJA2 Helmet50RR.
The following is a description of the use of each.

D Tracker
Applications:Motard race, Touring
Used with Utani Coil.
Purchased about three copies of Repeat.
Replaced and used since the vehicle was first purchased. Introduced the Uotani Coil in the process.

NINJA2 Helmet50RR
Traveling:Touring, mountain passes
Quantity:2 Buy SetRepeat.
Replaced Standard Plug BP5HACR8E.

Was the one you received as per Image?
As you can see in the image, the electrode is thicker than the one made by Denso, so I felt I could use it with the Votani Coil.

Was the installation difficult?
As long as you have a plug wrench, you can do it without any problems as long as you take care of the angle when tightening. Since the plug position is quite far back in both models, it is better to remove the plug cap and then blow the air to remove accumulated sand and small stones.
D Tracker is easier to work with if Tank is removed.
The NINJA2 Helmet 50RR was difficult to work on without removing the tank.

How was your experience with it?
D Tracker
I used it with the Utani Coil and was able to run with no trouble for the duration of use. The electrode melted and I could not run. The electrode did not melt and I could not run.
The Iridium plugs themselves are good, as they are used in conjunction with the Utani Coil, but the start-up was very good, and the torque feeling was Large.
The Iridium plugs were excellent in terms of starting and torque, but once the electrodes got dirty, starting became extremely difficult, so if you are using a Watani coil and your car is prone to getting dirty, the Standard Plug BP5HA is a better choice. I would recommend the CR8EK.
With the Wotani Coil combination, Life had to replace the Fee Ring after about 2500km because it became bad.
If the ignition system is not reinforced, Iridium plugs are good.

NINJA2 Helmet50RR
I replaced the Standard Plug BP5HA and it clearly improved the starting performance and torque feeling.
Since it is FI, the Plug will not be covered unless there is something wrong, and since the Demerit will disappear, I will certainly recommend this product over the Standard Plug BP5HA.
The ignition system had not been strengthened, and Life was able to last for about 5000km. I tried to replace it at about 5000km.

[Included Parts:were they on?
None

[Was there anything that disappointed you?
None

Point and hang of installation
Anti-seizure agent on the screw part of the Plug (Anti-seeds、CopperCompoundetc.) can be applied to prevent it from becoming a Trouble the next time it is replaced.
I've been doing it that way for more than a decade, and I've never had a problem with the plug burning off.
Also, it's not enough to tighten the plug as hard as you can, so read the product description carefully and do the work. View detail

I have w800. The time to change the ignition plug has come, so I bought it. As expected, NGK seems to be overwhelming in performance. I'm very satisfied. View detail

Used for DR-Z400SM

DR-Z400SM of 16,000km running, it is the exchange of the Plug also in accordance with having done the Carburetor overhaul.

Engine manufactured in '06 is in great shape.
I like the NGK Plug for it's peace of mind and it's economical for just a single cylinder! View detail

Maybe it's the Brushbo effect, though

It's time to replace the Plug.
I don't think there's a problem with the normal plug, but I was hoping it would lead to a slight increase in performance.
It's TWIN, not Multi, so the price is higher, but I think it's still Wallet friendly.

I think that the degree of difficulty changes considerably according to the car model such as removing the Tank.

After replacing the engine, it seems to have improved the starting, blowing, and power feeling?
Maybe it's the Brushbo effect, but it made me feel good, so I think it's good. View detail

spark plug review

I bought spark plugs to mount on my w800. Denso for performance and NGK for durability, so I chose NGK. The original version is equipped with CR8E, but I chose the iridium version of this product. It feels like the startability has definitely improved after installation. ---------------- I purchased a spark plug to attach it to the w800. NGK was chosen because it is said that the performance is DENSO and the durability is NGK. The original version is equipped with CR8E, but I chose the iridium version of this product.

It's good, but there doesn't seem to be a repeat.

The vibration in the idling to low rpm range is somewhat better and it seems to have become smooth.
I don't see any particular improvement in Power or fuel economy.
There seems to be no effect to say this, so if you ask me if the cost is good? If you ask me, I think it is bad....
I could feel the effect on the 400cc I was riding when I was a beginner. View detail

Expect to see improved performance.

I changed the carburetor on the D Tracker to TMR and thought it would be a waste if the ignition was bad even though the gasoline atomization was better.
I didn't see any changes as a result, but I'm sure it's burning more efficiently...! View detail

I don't know the difference.

I don't know what it would be like to use it on the KLX250.
I chose Iridium plugs and I couldn't see any difference between them and regular Plug.
Or rather, I didn't even notice a difference between before and after changing the Plug.
Is this an individual difference? View detail

If you want to power up, Windshield IRIDIUM

If replaced, there is an obvious change in the blowout area
If you ride it, you will notice the difference in torque and power at the beginning of the ride
I think it's a great deal if you can power up for this price

For those who have only used the Standard Plug BP5HA, I think it's a good idea to give it a try
It's well worth it, so … View detail

It's a staple and has excellent cost performance

[Installation and feel]
The NINJA2 Helmet 50RSL has an oddly tucked-in plug position, and the plug It is hard to turn a wrench when wrench is hard to enter and it has a hard time to turn a wrench at the time of removal It is not a story not limited to this Plug, but be careful not to damage the screw thread etc. at the time of installation Use
I change them about every 6,000 to 7,000km and I wonder if I feel better after the change degree In other words, it may have a long life span

[Quality/Cost performance]
If it is a single-cylinder car, it can be replaced without hesitation If you look at the total life of the engine, it will be cheaper, so don't be stingy and replace it Yes View detail

Compared to CR8E

I wanted to compare it with the CR8E and the Windshield IRIDIUM As a result, the result is a very good blow-up, except for the Windshield IRIDIUM I don't want to be! I even thought
If you want to buy CR8E for cheap because it's a consumable item, you'll probably buy CR8E, but Exhaust If you want to change the system to make a few more horsepower, switch to Windshield IRIDIUM I thought it would definitely be better to do so without sacrificing the slow torque View detail

Exchange at 26000 km Ninja 250 R CR8 EIX

I exchanged for CR8EIX Iridium plugs this time.

Even though I ran 26000 kilometers with the Normal plug, I was starting with one cell at a time, so I was not particularly crippled.

If it was worrisome there were the following reasons and I tried to exchange it daringly.

? Little stuck at low speed, easy to knocking.
? It became easy to stall when starting from a signal stop.
? It was hard to catch on departure in the morning at high altitude.

Especially the original Plug did not seem to be wearing Large, but after the exchange Idling got a fine-grained feeling, the rotation was light and became to indulge in Smooth.

Somehow, before the exchange I felt gritty feeling or rough feeling and the sound from the Exhaust System was also a loud taste, but instead of a more granular smooth sound I became Smooth.

When turning Throttle, it is light or stable, smooth and has a sense of security.

Even if it is not Windshield IRIDIUM, it may be getting better, but this time it was a result that I felt the effect after replacement.

I think that Plug looks and can be used, but I think that 26000 km is the distance that you can feel the effect when you exchange.
As a way of using Motorcycle, I think that we are running only Touring, running on a pass a little more speed.
Leisurely on expressways and ordinary roads ? ? ?.

If you feel stuck in the Accelerator operation or you have trouble with the replacement time, please refer to this impression.

I hope that everyone who reads Impre will help you. View detail
