Iridium Plug CR8EIX 4814

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.

[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.

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.

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.

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!

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.
