We bulk one is IT20 and not IK20.
Just you. U no makan nasi ah?

obviously not me coz i'm at the driver's seat

that fellar no makan nasi

or the door no makan nasi

I think it applies to all Iridium Power range.

Just read up 1 guy uses IT20 12K mileage = 20k kilometer. Spark center conductor habis.....

So I suggest not using our Denso Power IT20 more than 20K kilometer max.

Maybe yours is new. Mine closes very easily, but that was previously before I added some extra rubber to make its closing sound sound much more pleasant.

Mana link itu? Like that change also have to follow same interval.

From this link mentioned that the interval should be 30K miles for Denso Power.

what i saw is that it is designed to last 100k km under normal driving, but recommended to change at 35k km for optimum performance as it is high performance plug. if can only last 20k km, then i will just stick to campro oem plug and change it every 10k km. i still can accept if change at every 35k km. reasonable for the price too.

After reading more articles from denso overall (they never give exact life span)...I come to conclude in general Denso Iridium Power plug should be able to last maxed 50K mileage. By then probably performance degraded to max.

Most vendor recommended 30k to 40K change. I think I will either go for 30K if got $$$ or 40K if no $$$. Don't think I want it to go 50K...the eroded performance and fc probably did not worth that 10K mileage.

The post indicated eroded 20K is over 10 years old....so I guess technology has advance greatly. However global denso STILL list Denso Power IK20 as 15K to 20K kilometer vs oem/tough 100K. So.....up to your interpretation.

Then it is not 20K lah?
Yalo, better dun stretch it past 50K since SP problems will make car stalling, performance down and FC high.

if you believe denso, then the interval will be 30k miles which = approx 48k km.
so changing at 35k-40k km like i mentioned is reasonable.
previously i wanna buy tough, but it seems not much people selling. so i just take the power.

Denso global STILL give comparison of Power IK20 as 15K to 20K kilometer vs OEM/tough 100K kilometer....so...

true true. i wonder when is the time i installed it. my fc still high now.

Manada? That one is basic requirement for spark plugs and did not specify that it is for Denso Power.

Then dunno lah. Too heavy, tyres not pumped properly, no Firestorm.
Here is the pdf for the Denso recommended SP.

Mine sound exactly the same. How come they never solve the GB problem? Only changed your wheel bearing? O.o
I'm planning to send to CoSE during my sem break for the GB problem too.

They change bearing first. Because if gearbox needs to be repaired, it takes 2 weeks. So far no more whining after changing 2 bearing.

Oh! Means they changed the gear bearing? And I thought it's wheel bearing. Pai seh pai seh.
