【DENSO】Iridium Power Plug IX24 Review

First DENSO. first Iridium plugs (and then)

It was installed in July 2021 and replaced in August 2022, after 25 days of actual operation and 3,100 km of actual driving.
From the PRO mechanics. Insulators are too white and burnt." I was pointed out to him.
I didn't notice any glitches. ・・・・

We are currently reverting to the OEM specified DR8EA and seeing how it goes.
In comparison with Windshield IRIDIUM and new NORMAL with 3100km of use Not much has changed. It may be that the performance is maintained at the same level as that of a new plug. View detail

Compared with NGKWindshield IRIDIUM

[How is it used?
Model used:FTR223
Traveling:Street riding, Touring
Period of use:About a year or so (Replace after about 5000 to 6000km.)

Was the one you received as per Image?
Image is correct. I'm glad I bought one made by Denso because the construction of each part is excellent.

Was the installation difficult?
If you have a plug wrench, you can do it without any problem as long as you take care of the angle when tightening the plug, but since the FTR is located quite far back in the plug, it is better to remove the plug cap and then air blow to remove any accumulated sand and small stones.
No need to remove the Tank.

How was your experience with it?
As mentioned in the title, when compared to NGK Windshield IRIDIUM, the ignition enhancement Custom (Equipped with Uotani Coil) I think this product was better in terms of starting and torque feeling when I was not using the
The Life of the Plug itself was the same for both.
The price of this product is higher, so if you think that you should spend money on a plug that needs to be replaced, even if it is a custom part, do not choose this product. The price is higher than this product.
I didn't want to use it with the Utani Coil because I didn't want to have any problems with the thin electrodes due to the characteristics of this product.

[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

My first DENSO, my first Iridium plugs (Part 2)

I've finally replaced it and have about 160km on it so I'll post my thoughts.

[How is it used?
In recent years, Tandem touring is the main way for elderly couples to relax on a day trip.
On the way down the road and at high speed, about 90% of the time I drive at less than 6,000 rpm, and the only time I rev to high rpm is when I'm getting out of a crowd of cars.
The ignition system has been strengthened with full power + MSA + Nagai Electronics Ultra code.
The PlugGap was expanded from 0.65mm when it arrived to the Uotani specification (about 1.15mm on average).

How was your experience with it?
I am satisfied with the initial performance. I'm looking forward to seeing how long this can be maintained...

How did it compare to other products?
This is a comparison with the BuRiskDR14ZC that was installed just before.
It's been over a year, and I'm comparing the records to my memory when I installed the new BuRisk...

1) Cold starting performance and warm-up time
Both are good (although my vehicle has always required a Starter, even in the summer months).
2) Warm starting performance
This also makes no difference (my vehicle is "Cell One Shot." (It's not possible to do this, but if you agitate the Axel a little, you can start one).
3) Runaway feeling after warm-up
BuRisk has a "Fan!" But in this Windshield IRIDIUM, there was a scene that made me feel like I was completely burnt out. "Van!" Yes
4) Clutch meat feeling at start etc.
Both of them are well connected, but...
Even when I was about to stall, the BuRisk stuck to its task well and I had no worries, but I did have a few close calls with the Windshield IRIDIUM.
5) A sense of puffiness
There was a soft, fluffy rise in BuRisk.
This Windshield IRIDIUM is not that great, but it wipes beautifully with a sheer and even grain.
6) Running low rpm from near Idol
There was no jitteriness in the Idol keep running if both were low GEAR.
Even at 40-50km/h in 5th gear at around 1500-2000rpm, the Axel revs up smoothly, which is the same for both.
With the way I run, the most pleasing characteristic is that I feel good here.
7) Embracing characteristics
"Pan! Pan! accompanied by the flashy After Fire. "Ngh! Gah!" and a vehicle that was emblazoned with...
By strengthening the ignition system and the B-Risk "ParaParaPara..." It was improved to a gentle After Fire and a large embrasure that seemed to pull a thread.
With this Windshield IRIDIUM, it's not quite that bad. "Kark." I'm not complaining about the gentle embrace of the "I'm not complaining".
8) General Comment
My impression is that the DensoIX24 is nowhere near as good as the BuRiskDR14ZC in terms of ignition performance.
However, I felt that the difference between new and degraded is too large for BuRisk.
That's one of the reasons I decided to replace it, so I'll be watching to see how well Iridium Power maintains its performance.
If the performance drops to the point where you can feel it, it is a cheap and reliable OEM designated D (R) Maybe I'll go back to 8EA.
Considering the ignition, durability, quality... and Cost.

[Points to note]
Some people do not recommend Iridium plugs for older cars.
The reason for this seems to be that it is not easy to revive a vehicle with engine or ignition system problems when it is CUBed. View detail

My first DENSO, my first Iridium plugs

How it was purchased.
Before the ignition system was strengthened, it was NGK D8EA of OEM specification for more than 30 years, but now it is using Brisk ZC.
I was looking for a JAPAN high performance Plug to replace it in the near future.
Originally, I wanted to try the Moto DX with D-Shape electrodes that claimed long life because I was a day special.
Screw diameter 12mm and Screw length 19mm are not available in the lineup.
Large difference between DR8EIX and IX24 seems to be the grounding electrode structure.

Was the one you received as per Image?
YES, I was happy with the resin Cap of the electrode protection because it is an expensive Plug.

Was the installation difficult?
I haven't installed it yet, but I'm sure it won't be difficult since it's a consumable removal.
Since it is the first time to remove and install the plug in 30 years, I will try to do it after checking the setup properly.

How was your experience with it?
Please let me evaluate the use in the future.

[Included Parts:were they on?
If I had to pick one, I'd say Terminal nut.... It was attached properly.

[Was there anything that disappointed you?
JAPAN's industrial products!!! We are confident that it will not fail to meet your expectations.

Mr. Manufacturer is "Excellent ignition performance without increasing the spark gap. 、 "Don't adjust the gap.
It is claimed to be 0.65mm, but it was 0.65mm when it arrived (all four bottles I bought were perfectly aligned).
1.I spread it to 1mm〜1.2mm (Ignition system is Uotani Full power + Nagai Denshi Ultra code. (Uotani's specified value is allowed up to 1.3mm).
Although it is not used yet, it is expected to be a large flame core that the U-groove ground electrode produces.
I would like to impresion after use later. View detail

It is satisfied.

It is the second purchase.
Although it is a little expensive, I bought it again because it was OK with a single cylinder 1 pc.
I feel Idling has stabilized, I feel like Power got up ... I felt.
