Go Denso website. Also read all over the net...can't remember. The 0.4mm recommended mileage is 30K, so converted to KM is 40K.

0.4mm meant for performance but shorter life. 0.7mm is the longer life 120K mileage version.

like that i need ask refund from zeng ady.. haha

Iridium Power range is purely for performance freak and FC freak. The long life version is normal OEM manufacturer version that can last longer but uses platinum tip. You want pure performance improvement, Iridium Power is the one to go but only can last twice as long as our normal spark plug.

normal plug last for 10 k only la. u go sc service.. every 10k. they change your plug

How come our service 20K only change spark plug?

Hi All.. I'm New Here..

tak tao lo... but mine is change every 10k. but now at iridium ady. and wont change plug untill the plug is burn. last time i use nissan sunny. i never change my plug for so long also nvm.

then our Original car paint is 2K paint??
else i go buy this 2K paint diy kit also no use...

Found u like to do a lot of reseach

The older iridium plug that you use might be longer life wan...120k. The one we're having is performance iridium, not long life iridium. So will wear out way faster.

Nice to meet u....

look like is it GEN2

Bingo

for the statement tat i post b4,do u think 300km for half tank petrol is makan minyak ??

my engine light suddenly light up... dunno whats prob......

anyone know what caused?

enigne burn signal?? haha.. jocking.. need disgnose 1st. baru tahu ma

Sometimes birdshit drop from the sky onto ur head.. U kena first prize mah.. "zhong tou jiang".. But no money to collect..

Code is IT20.. Although some sellers will tell u that IK20 also can use, but the heat range is different.. So stick to IT20.. IT20 was specially made for Campro.. But the specs as in gap, socket size are the same except for operating heat range.

OKOK.. i placed order for 10sets ady.. So going to start the bulk here lah.. XD

Not lurking lah.. haha.. Class started ady.. So only will be online at night.. Morning im busy looking at my new hot lecturer. XD She is an indian mix singh but omg hu-ge clea-va-ge.. Damn slim somemore.

For savings purely on FC is to install grounding cable, air filter, denso iridium spark plugs, and lightened crank pulley and lightened cam pulley.. For performance, install full exhaust system first b4 going for lightened crank and cam pulley.

Haha later sure kena pecah window..

Yeah read that too.. its 30k miles.. so around 48k km.. But the 48k km is when performance starts to drop due to the head starting to become rounder instead of the pin like sharpness.. Lifetime of the plugs is still ~100k km. But advisable to change at 70-80k km.

Welcome.. Whats ur car color, line and transmission?

Added on July 7, 2011, 6:50 pmExcerpts taken from the Denso website FAQ

Q. How long will Iridium Last?
A. Iridium use represents the most significant technological advance in automotive spark plug manufacturing, since platinum was introduced in the early eighties. As vehicle manufacturers produce increasingly complex and efficient automobiles, there is a greater need for long-life plugs that can tolerate leaner fuel mixtures and improved combustion processes.

DENSO has responded to this need by developing its Iridium alloy, originally for OE applications. For example, many newer Lexus’ and Toyota models carry an ultra long-life Iridium plug variation (.7mm with platinum tipped ground) that is capable of up to 120,000 miles of service.

DENSO Iridium Power plugs, with their .4mm center electrode, have been developed for performance applications. Because gradual wear will “round-off” firing points over time, the concentrated firing power and voltage requirement benefits will be reduced. For this reason, DENSO advises replacement after 30,000 miles.

As for the voltage requirement benefit, stock car ECU have a compensation feature to increase Voltage to the spark plug when the spark plug starts to wear out and the bridging voltage increases. Therefore performance difference will be minimal except in extreme cases where high revs are applied all the time.

FYI P2 SC also offer Iridium Power plugs in their service centre and if u change to those denso plugs they will stamp in the booklet that the plugs are valid for 100k km according to my friends service booklet.

my persona milage about 1900km...the FC i think very bad... telan minyak betul.. but, some friends told me that the FC of persona will be better after 5k service..is it true????
drive to kedai about 3 km can see the fuel meter drop veryyyyy crazzyyyy...huhuhu

if u drive all short short journey and have a lot start and stop engine in a day, SURE makan minyak.

Is it your right foot or AIFM kong? My FC is getting by the day. Even slightly below your mileage. 65/35 highway/city...getting abt 8.2l/100km. Very light footed. Slow and steady acceleration.

no... i not drive a lot..just once a day and usualy at nite..coz i go to work by motocycle...

i dont know la..IAFM can kong hah? ermm...i drive slow n steady too.. btw..my car manual...i think at highway my fc better..long journey ofcourse rite..
