NGK Platinum plugs - use how long?

[Bigtoothpick]

hi all - my NGK Platinum plugs hav been used about just under 20,000km (my car mileage about 23K km). Do i need to inspect / replace the plugs? last time I told my mech, he said no need to change, and he didn't take out to check... thanks for any advice....

When I did my 40+k servicing, the mech took out my stock NGK (or denso??) Platinum and said that they are allright. I guess platinums really last a long long time.

For Singaprean car owners. Pt plugs can most likely last the lifetime of the car ownership. They go up to 160k km if they are double Pt. Normal Pt should go 100k. After that is grace.

[Zrun]

I think rated to last nearly 150k km.

damn. the alpine mech said no need to take out and check the plugs unless car experience some jerking or whatsoever. mine is inside for abt 40k liao.

[Genie47]

Yours are the Pt ones? Must still take out to check.

Wah!!! 150000km!!!

 

What about denso iridium? which can last longer?

[Genie47]

Ir plugs can last long but they are damn overpriced. Pt plugs should actually be more valuable than Ir because Pt as a precious metal is more valuable.

yeah lor. maybe go another workshop ask them help me check

OIC... wah, like that quite worth leh... i paid only $36 for 4 pcs. My car usage so low, if can tahan till 100K km, i think will outlast my COE

[Bigtoothpick]

Any sparkplug can easily last 50K.... be it platinium, iranium or copper spark plug, but the performance will degrade after 10K..

 

I used to own a splitfire sparksplug and use it for 40K, according to the manufacturer, it can last 100,000 miles.... nothing wents wrong, just that my backside itchy and I bought a set of denso copper plug at $10...

 

upon changing my splitfire sparkplug to the copper plug, i can feel additional immediately. I believe that it is not becos that the denso cooper is good... just that my platinium plug was worn and although it is still usable, the performance drop... I dun feel anything wrog with the platinium plug becos the degrade in the performance is so slow over 40K....

 

Try it yourself and u'll know what am i trying to say... its only $10 anyway...

[Genie47]

It's not that the Pt plugs are worn. Any copper plug has better sparking efficiency compared to a brand new rare earth metal plug.

[Seanboi]

where u got those copper plugs?

Hi,

 

what do we actually check / look for so that it's still considered good and usable?

hi,

 

read that iridium plugs are actually more efficient (why?) that's why it's more expensive. is this true?

 

thanks.
