Hi bro, you may find on this site

General information about Iridium spark plugs.

Iridium is an extremely hard metallic element, related to platinum, which is thought to occur on earth primarily due to an enormous meteor impact millions of years ago. Other than it's hardness, the main property which makes Iridium attractive as an electrode material for spark plugs is its extremely high melting point (almost 2,500 deg C).

Since late in the 20th century Iridium has been used in alloy form as material of choice for construction of Spark plug and industrial igniter electrodes. Pure Iridium is difficult to work with, very brittle and does not have great electrical conductivity hence alloys are used to give the best combination of these properties. An Iridium alloy electrode is able to deliver good conductivity and extreme hardness. The result is that an Iridium electrode can be manufactured with an extremely small diameter, when compared to a traditional copper or even a platinum tipped electrode, without compromising the useful life of the electrode or spark plug. The narrow diameter concentrates the electrical charge and therefore a much lower voltage is required to jump the spark gap. This is beneficial in several ways:

A lower voltage is required, this reduces load on a vehicle's ignition system (less strain = less chance of failure)
A larger gap can be supported without increasing load on the ignition system (Larger gap = larger spark = more efficient combustion)
A more precise spark every time, delivered in the correct position and with the correct timing (More efficient combustion)

Assuming a suitable Iridium plug is available, benefits you are most likely to see are:

Improved throttle response
Improved economy (though this depends largely on how much you enjoy the improved throttle response!)
Increased plug service life (Depending on design, an Iridium plug could last up to ten times the life of a standard plug with little reduction in efficiency over the plug's lifespan)
Increased engine power (Don't expect to double your horsepower but a 1 - 3% increase is possible)
Improved (reduced) emissions.

Well it is clear that iridium plugs are good enough to stand the extra heat from your super duper ultra kuat firestorm (as i heard that firestorm reduce the life of traditional plug significantly due to extra heat it generates)....but whether is adds additional benefits on the already kuat plug is questionable...

belum cuba belum tau.

Thanks for the link

I'm not sure what kind of Iridium plugs the Preve is using, but suffice to say many Preve owners have installed it with positive feedback. I'd like to hear what they have to say as well.

Anyway, If you have read previous discussions on this product, you will see that it has been clarified by the Penang distributor that Firestorm does not generate extra heat in your ignition systems.

Preve CFE stock uses NGK Iridium ILKAR7G7 size

Preve Exec using same as all normal Campro... Bosch HGR7DQI, Denso IT20...

haha glad to know that u are happy with the add on~~
mind to share the experience in details?

coz i also read some where which a guy claim that his plug was toast after a few months of use ~~~cannot recall what car model~~and the discussion goes on recommending him other type of plugs~~

hmm but it is hard to believe 5x stronger spark (as it claims) does not add additional heat~~ possible?

Thanks

My experience not in a Preve (was a Saga FLX SE and Fiesta), so irrelevant to tell here also. If you are a member of PREVOC, maybe you can ask in their fb?

I'm not savvy in how electronic works, better ask the seller (flashaholic) instead of me

Still keen to know is there any other aftermarket plug for CFE.. it seems like only NGK produces it.. that's why it's overpriced.

Most Iridium we see @ the market will cost less than RM200..
CFE's being RM400 is just way overpriced... but if there's not enough numbers to justify for other makers to participate.. then we will forever need to live with it.

I went to few Proton showrooms, there was no manual Preve test drive unit. Any member here has Manual Preve? Need some feedback on the NVH, build quality and driveability. Thanks.

may i know wat is super firestorm? i only know got normal one..

official registered test drive unit for all proton showroom is premium spec, unless they use unregister unit for test .
can try to join member TT on preve club maybe u will have chance to hear what owner say

I haven't had the chance to look around Preve's headlight. Just a question, is it simillar to other cars where we only need to unplug the power cord and cover, and unclip the light bulb?

I sat in Preve CFE few times, so i roughly know the NVH level. But i want to know is the manual version NVh better or worse than CFE.

Haven't tried too

Preve Exec CVT will be noisier than CFE due to its CVT whining...

But Preve Manual is better than Exec CVT for sure and probably could be better than CFE as long as the soundproofing materials/level are same...

It's like normal Firestorm, but product size is bigger and sparks stronger.

coil mat

rm170 same price with ori wor..

I am not here to sell you stuff. I am here just to correct you and to crush the "what I heard" rumors.

the 3rd plug need to change ad,lol...

memang dah change pun. so cheap oni. lol
