hiye all, pls come and share your opinions about these 2 types of plugs

welcome for all who are using it already..your comment is very much appreciated

Pls post your true experience only..dont post fact that u heard

to those who want to upgrade to these plugs..pls tell which 1 is your choice and why?

i saw some previous post sayin that platinum can perform better than iridium

while iridium can last longer than platinum and has higher melting point..

pls share

iridium..coz it is very very expansive..but can u tell me what engine?

planned to put it on my s4ph...campro

btw u're using it?

from what i had read iridium can last longer than platinum. performance wise, iridium should be better than platinum as well since the centre electrode is finer.

personally i never tried platinum. i used hks iridium, so far so good, never had any plug issue even on high rev 9k rpm. the only downside i can think of is the price tag...

oh hks iridium..any improvement felt?..did u changed spark plug cable too?

btw how much u bought for hks plugs?

Both iridium and platinum plugs do not improve performance directly. They are suppose to complement the modifications done to the car. These plugs can be purchased in a variety of heat ratings to cater for the modifications of the car. They are also meant to be durable to withstand the punishment of modded engines. I used NGK IRIWAY 7 and 9 iridium for my previous Satria 1.8 turbo and currently using NGK Laser Platinum for my WRX.

Durability is evident as I've used the IRIWAYs to about 50k km before changing, whereas I'd usually blow standard plugs by about 5-10k km. Based on the service records, the original Laser Platinums that came with the WRX lasted till 80k km before the car was sold to me.

what's the brand of plugs which have been designed to last 100k kms again ah jason?

i've been on the factory plugs until now (25k kms) and really have to change them lest ruining the engine looking for a model that can last me up to 125k kms if possible

Denso iridium can last 100K if I am not mistaken
Volker iridiums stated 160k instead

agreed with sleepwalker, u can't expect hp gain just from iridium spark plug. if u have hp gain by just adding iridium plug on stock engine, then ur previous plugs must had fouled out.

so overall do u prefer to use back laser platinums or iriways the next time u changed plugs?

That's going to be another 55k km away for me to think but since the stock plugs are NGK Laser Platinums, so will continue using the Laser Platinums.

bro wats the meaning of laser platinums?...how much ar?

woot gonna change to NGK. i'm not sure volker has the proper heat range for my car though. summore some P2 mechs say NGK (jap) more compatible with jap engines than other foreign brands, although im not sure whether its true or not la.

thanks again fly away again

always does..

That's just the name for that particular NGK model. Average cost is about RM45 each, so 4 for about RM180.

Added on September 6, 2007, 6:38 pmWell, Volker claims that they have the conversion charts for the heat range and from the looks of the chart, they have matched their heat rating according to NGK, the higher the number the colder the plug. However, their heat range is only from 6 to 9. If you need anything hotter than 6, don't think you can use Volker.

i'm using NGK g-power platinum... lower grade than the laser platinum i guess.... serves me well so far... performance more or less like bosch super4.... iridium havent try before... no money lar....

tried denso iridium b4?

Does denso iridium go so hot? Most iridium and platinum plug heat ranges are from 6 to 9 (based on NGK).

then what are denso iridium heat ranges?

Opps.. actually they have from 5 to 10, so you might still be able to find one for your car. However, in their website they have Proton but not Perodua but you can most probably use your equiv Daihatsu model to check.

still on factory plugs la, meaning i have not changed them since i got the car

hmmm im using the same plugs as a wira or something, gotta check back with my dad 1st.
