the Denso Iridium Power IT20 spark plugs can optimally last for how much mileage?

Denso recommended 30K for optimal performance. Ppl here using like what is mention above.

I'm going for 40K instead of 30K coz pocket no money...might ask technician to check if plug is still good at 30K (optimal), coz if gap is already large enuf to degrade performance noticeably, I will change early.

ok thanks for the infos, after changing the spark plugs need to do tuning?

why they dont apply this cvt on persona sv?

sure will.. coz i couldnt find one persona jibais who've given a review of it. 
but expecting more or less with stock..

Hi all, I'm back...just to update my iafm module is kantoi ady... Clocked 120k km today...

Hi..anyone aware of the new Persona executive? Look like previous persona H-line with reduced price.


Proton Persona Executive (MT / Solid) : RM49,938.00
Proton Persona Executive (AT / Solid) : RM52,938.00
Proton Persona Executive (MT / Metalik) : RM50,388.00
Proton Persona Executive (AT / Metalik) : RM53,388.00

if getting used persona, the earlier persona SE (with leather seat and chrome door handle), vs persona elegance b-spec, which one better? both price almost same...

actually i thought the persona SE version looks better than elegance b-m line version.
just that side mirror on the persona SE too small. my dad keeps complaining when he drives my gen2. need to replace side mirror to elegance model for him if really getting the SE version...

Screeching noise during braking is usually brake pad worn out. Looking at your mileage, so fast the brake pad worn out? 
However, do check if the brake pad is worn out.
Other possibilities have to wait for other sifus.

Fairly new car, i dont think the brake pads wear out in 5k mileage? Thats got to be pretty serious. I mostly day to day driving to office and home, no hard braking. I went to another SC also told me its a norm for persona. I just cant accept that its a norm when other cars can drive normally. I remember my previous Iswara drove for more than 80k mileage still no sounds.

Even changing to other pads, it might still come back after a while. Mine does. Now getting louder. The pads at rough looks still have at least 50% left...

Used to ignore the screech sound (H-Line sound insulation lessen it in the cabin) but now getting more frequent and louder. Will have to re-check it when I change tyres somewhere next month.

Warped and uneven will cause sound ke? I kena mine, no sound at all. Only braking to stop, the steering vibrates.
Btw, my brakes got no screeching sound since new *touch wood*

guys, i wan to ask. last time i service my car at authorized SC my meter was 1200km. now my meter is 4570km.
i checked the sticker the SC stick at my car is 5000km.

my question: should i service my car:
1. when my meter reach 5000km
2. when my meter reach 6200km (1200km + 5000 km)

Which one? if the answer is number 1, i need to service by tomorrow before balik kampung. if the answer is number 2, i will service after balik from kampung.

This 1 need to drill right?

Cuz what i afraid is. If i put the clip, and accidentally hit it. Then the fender might spoil too.

Then is better. The picture you have on your signature is your car?
r3 bumper also have the gap problem?
Do u know the price with paint?

lama dah tak jump gambar keta hantu air jin choo bee in your siggy. blom juai ka?

Guys, Any good rim to recommend?

almost 2k for 1 set. and the tyre sure not cheap haha
