Iridium Netzstecker IU27A

I've been using this Iridium power plug ever since I switched to my previous RSV4 Factory and then RSV4 RF (2016).
In the case of RSV4, NGK's Windshield IRIDIUM is not compatible, so I think Denso is the natural choice.
For gasoline engine, good mixture, good compression and good spark are important, so we expect good spark by replacing with this Plug.
As the effect of Iridium plugs, there are low fuel consumption by the increase of combustion efficiency, improvement of engine power, improvement of acceleration, improvement of startability, carbon does not accumulate easily, etc., but I think that the difference to the extent that it can be felt is not obtained, and in my case, I do not know the difference from the OEM RPlug from the beginning. I don't know the difference from OEM RPlug because I have changed to Windshield IRIDIUM.
But for now, I think the engine power is out when I run Circuit, and the starting is very good even in the morning of winter, and the mileage may be a little better than other RSV4 when I go Touring.
Well, when it comes to fuel economy, it's pretty muchQuantity on how you ride.:Pair (for Left and Right) It may not be helpful because it is done.
By the way, when I did the dyno measurement before, it was 187ps at the rear axle, so I guess there is some power coming out. (Iridium power plug, DNAAir Filter, AKRAPOVICFull Exhaust System, measurement at the beginning of autumn with the RACINGMap attached to the Full Exhaust System)

Next time I'm going to replace it with an Iridium racing plug.

By the way, changing the plug in the RSV4 is quite a hassle, especially changing the front bank.
When ECU, variable Air Intake Funnel, Air cleaner box are removed as shown in the photograph, it pulls out the Brown pain Brown long Plug cap and removes the Plug which is considerably in the back of the Head, but when Extension is attached so that the Plug wrench may reach to the Plug The part of the Head of Frame interferes and does not enter, and even if somehow it enters, when Plug is removed, this time it does not remove. 。 It may not be able to be removed without using the technique that the Extension and the Plug wrench are pulled out separately by removing the Plug wrench from the Extension once when combining the Extension and the Universal joint of the exquisite length (about 13cm) and pulling it out. It may not be possible to remove it unless you use the following technique 。 So I decided to use the middle for the work's Kill.

Motorcycle reacts to Linear to Axel who knows that Pickup and Torque are going up. Becoming Peeky If it says badly Replacing it As the thinness of the fuel in the low and middle speed region became particularly concerned, it was mostly a matter of concern
Unfortunately the startability deteriorates with about 3000 approx. Installation Engine Stall when opening Axel near Idol
EngineStall may be fuel thin as well?

I used Denso's Plug for the first time.
IU 27 A, not IU 27's polarity, is unipolar.
Iridium plugs had never been put in MONSTER
I'm looking forward to it but startup ability and dandruff rise are listed.

It exchanged for the iridium of the denso from pure NGK.
a form is completely different first -- ~ -- Why is different like this? it is wonderful.
Although engine oil and an air filter are exchanged simultaneously, a response is sharp too! If it exchanges from an authentic positive one, it will be an iridium plugs too!! It is a five stars!

It exchanged for iridium power at about 3000 km after purchase with the new car.
Since WR is an injection, there is no change about engine startability.
There is no change to the extent that power up and improvement in fuel consumption are also astonished.
although it did not expect that the engine performance would rise only by one plug changing since it was a motorcycle of the one cylinder, of course -- an axel -- attaching -- it is thought that it became good.
With consumable goods, since it is moreover a one cylinder, I hear that it ends with one and it uses, being convinced.
